Harmattan season in Ghana

What you notice first

The first sign of harmattan is not dust but the temperature at five in the morning. You wake up cold in a country where you did not pack for cold, and the fan you left on all night now feels like a mistake.

The second sign is your lips. Within a day or two of arriving into a proper harmattan, they crack. The inside of your nose dries and may bleed a little. Your throat feels scratchy at the back in a way that is not quite a cold. Skin goes pale and tight and shows white lines where you scratch it, which is why Ghanaians carry shea butter through these weeks and why every shop has a wall of it.

Then you notice the sky. It is not cloud and it is not fog, though at a distance it behaves like both. It is a pale grey-brown wash across the whole horizon, thickest in the morning, that makes the sun readable with the naked eye at noon and turns a view that should run for kilometres into a view that stops at the next ridge.

Everything gets a film on it. A car washed in the evening is dusty by mid-morning. Laptops, kitchen surfaces, the inside of a window left ajar, the top of a suitcase — a fine, pale, gritty layer arrives on all of it and cannot be kept off. You wipe things twice a day and stop caring by the third day.

What harmattan actually is

Harmattan is a dry continental wind that blows from the north-east, out of the Sahara and across West Africa towards the Gulf of Guinea, carrying fine desert dust with it. It replaces, for a few weeks, the moist south-westerly air that comes off the Atlantic for most of the year.

The mechanism is the seasonal north-and-south migration of the band where those two air masses meet. Through the middle of the year that boundary sits well north of Ghana and the country is under moist ocean air, which is what produces the rains. Towards the end of the year it slides south, the dry continental air takes over, and the north-east wind runs unopposed down to the coast.

The dust it carries is extremely fine — finer than beach sand, closer to talc — which is why it hangs in suspension rather than settling, and why it gets past window seals and into electronics.

Humidity falls hard, which is the relief, and the day-to-night swing widens sharply, because dry cloudless air loses its heat quickly after sunset. That is why harmattan nights in the north can be genuinely cold while the same afternoon was punishing.

The wind is also why this is burning season in parts of the country. Dry grass, dry bush and deliberate land clearance mean smoke joins the dust in many rural areas, particularly in the savannah belt, and the two together are what makes the air feel heaviest.

When it arrives and when it leaves

Harmattan generally reaches Ghana around December and eases through February, but it does not run to a calendar and you should not plan as though it does. Some years it arrives in late November and the whole of December is hazy. Other years the coast barely registers it until January and it is gone by the end of the month.

The season also comes in pulses rather than as a continuous state. A thick spell of several days gives way to clearer air, then returns. People in Accra talk about harmattan arriving and leaving two or three times over a season, which is exactly what happens.

The north gets it earlier and keeps it longer. Tamale and the Upper regions can be under dust while Accra is still humid and clear, and the north can still be hazy when the coast has moved on. If your trip runs south to north, you may effectively travel into the season.

Nobody can tell you in advance how strong a given year will be. That is an honest limitation, not a hedge. If dust genuinely matters to what you are planning — a photographic trip, a chest condition, an outdoor event — the workable response is to build flexibility into the itinerary rather than to search for a forecast that does not exist.

The wider picture of how this season sits against the rest of the Ghanaian year is set out in our guide to the best time to visit Ghana, and the month-by-month detail in our Ghana weather by month breakdown.

Where in Ghana it actually bites

Harmattan intensity falls off steeply from north to south, so where you are matters more than when you go. The Upper East and Upper West, around Bolgatanga, Navrongo and Wa, sit closest to the source and get the thickest, longest dust. Tamale and the Northern Region are close behind.

The middle belt — Kumasi, Techiman, Sunyani and the Ashanti towns — gets a real but moderated version. Mornings are hazy, the air is dry, the evenings are pleasant, and the dust is noticeable rather than oppressive. Kumasi in January is one of the more comfortable places in the country.

Accra and the coastal strip get the mildest version because the ocean moderates everything. Some years the capital gets a pale sky, cool nights and dusty cars and little else. Other years the dust reaches the coast properly and Accra genuinely hazes over. The Western Region, wetter and more forested, tends to feel it least of all.

The temperature pattern deserves its own note. In Bolgatanga and Navrongo, harmattan nights can be cold enough that people sleep under blankets and children go to school in jumpers, while the same day's afternoon is fierce. Visitors who packed exclusively for tropical heat find this genuinely uncomfortable, and a fleece for the north in January is not an overreaction.

Flights, visibility and what to do about it

Harmattan dust can reduce visibility enough to delay or divert flights, most often early-morning departures and arrivals, and most often on the domestic routes into the north. It is not a routine occurrence, and in most seasons most flights run normally, but it happens often enough that it belongs in your planning.

The mechanism is straightforward. Visibility is at its worst in the hours around dawn, before the day's heating lifts and disperses some of the haze. A morning flight into Tamale is therefore more exposed than an afternoon one, and an aircraft may hold, return or divert if conditions at the destination fall below minima.

The practical responses are the boring ones and they work. Do not book the last possible connection. If you are flying domestically to catch an international departure from Kotoka the same day, you are taking a risk that a night in Accra would remove entirely. Book the earlier flight out of the north and sleep in Accra before a long-haul.

Check with your airline directly rather than relying on a booking site or a weather app, and keep the airline's number saved rather than buried in an email. Schedules, minima and rebooking rules are the airline's to state, and they change.

Consider the road as the fallback. Kotoka to Kumasi is around four and a half to five hours by road in reasonable conditions; Tamale is considerably further. Knowing in advance whether a driving alternative is realistic for your route turns a cancelled flight from a crisis into a long day.

What the haze does to photographs

Harmattan flattens distance. Anything more than a few hundred metres away loses contrast and colour, the horizon disappears into a pale wash, and the wide landscape shot you travelled for simply will not be there. This is the single most common disappointment of a January trip.

The subjects that suffer are predictable: the view out over the forest from the Kakum canopy walkway, the escarpment at Mole, the hills of the Volta Region, anything shot across water, and sunsets, which go from gold to a dull orange smear. The sun itself can often be looked at directly through the haze, which tells you how much light is being scattered.

The subjects that work are close ones. Markets, faces, cloth, food, weaving, drumming, doorways, animals at close range, anything within about fifty metres holds its colour and its detail. Harmattan light is also very soft and directionless, which is flattering for portraits and forgiving at the middle of the day when normal tropical sun is brutal.

Shoot early. The first two hours after sunrise are the most workable, partly because the light is low and partly because there is often slightly less airborne dust before the day's traffic and wind stir more of it up. Late afternoon is second best.

Protect the equipment. Fine dust is the enemy of lens mechanisms and sensors, so change lenses inside a vehicle or a bag rather than in the open, carry a blower and a microfibre cloth, and keep the camera in a sealed bag when it is not in use. Bring more cleaning cloths than you think you need — they come back grey.

Skin, chest and eyes

Harmattan dries out everything with a mucous membrane, and the discomfort is real rather than cosmetic. Expect cracked lips, dry and tight skin, a scratchy throat, gritty eyes, and a dry nose that may bleed slightly, especially in the north.

The response is unglamorous and effective. Drink considerably more water than feels necessary, because you lose moisture through your skin and breath without sweating visibly. Use a heavy moisturiser rather than a light lotion — Ghanaian shea butter is sold everywhere, works extremely well and costs very little. Lip balm in a pocket, not in a suitcase. A saline nasal spray helps more than most people expect.

Eyes need attention if you wear contact lenses. Dust and dry air make lenses uncomfortable within hours, and rubbing grit into an eye is how a minor irritation becomes an infection. Bring glasses as well as lenses, and lubricating drops either way.

Respiratory conditions are where this becomes medical rather than inconvenient. Asthma symptoms commonly worsen in harmattan, and anyone with asthma, COPD or a similar condition should travel with their full medication, including a preventer and a spare reliever, and should speak to their own doctor before travelling rather than taking advice from a travel page. Children and older relatives are more affected than healthy adults.

Harmattan also coincides with a season of raised respiratory and meningitis risk in the belt across northern West Africa, which is a matter for a travel clinic and current public health advice, not for us. Ask about it at your pre-travel appointment along with your routine vaccinations.

Driving through the dust

The dangerous hours are dawn and dusk, when low visibility, low sun and a dusty windscreen combine. That combination is far more likely to cause a problem on a Ghanaian road than the dust itself.

What happens is this. The windscreen picks up a film of fine dust. You clean it with the wipers, the wipers smear it, and then you drive east into a low sun and the screen turns opaque. On a two-lane road where oncoming traffic overtakes into your lane, that is not a small thing. Stop and clean the glass properly with water and a cloth before you set off, keep washer fluid topped up, and pull over if you are blinded rather than driving on hopefully.

Unsurfaced roads throw up dust clouds behind every vehicle, and following a truck on a laterite road in harmattan means driving into a solid wall of orange. Hang back a long way. On the roads into Mole and across rural districts this is the norm, not the exception.

The main corridors are surfaced and hold up well in the dry season. The Accra–Kumasi road, the Accra–Cape Coast road through Kasoa and Winneba, and the route north to Tamale are all driveable, and the dry season is when road travel in Ghana is at its easiest. Night driving is a different matter and I would avoid it in harmattan more than at any other time, because the dust scatters oncoming headlights and haloes them.

Cabin air filters clog quickly, so ask for recirculation rather than fresh air in heavy dust. Our guide to driving in Ghana covers the wider road conditions and the licensing side.

Why the parks are at their best anyway

Harmattan coincides with the best wildlife viewing of the year at Mole National Park, and that is not a coincidence — the same dryness that cracks your lips is what concentrates the animals.

As the season progresses, seasonal pools and streams across the park dry up and the remaining water sources become the only option. Elephants, antelope, warthog and buffalo come to them on a schedule that guides know, which is why a walking safari in the dry months has a target rather than a hope. The grass is short and burnt back, so you can see through the bush instead of at it, and animals that would be invisible in tall wet-season grass are in plain view.

The haze does affect the long views from the escarpment, and it will take the drama out of your wide shots across the plain. The animals themselves photograph perfectly well because they are close.

Walking safaris in harmattan have their own rhythm. Early morning is cool enough to be genuinely pleasant, which is rarely true at other times of year, and the midday heat still arrives. Take a light layer for the first hour and remove it by nine.

The north in harmattan is a different trip

Northern Ghana in harmattan is the version of the north most worth seeing, dust included, because the roads are firm and the heat is survivable in a way it is not in March or April.

Larabanga's mud-and-stick mosque, the Paga crocodile ponds, the Sirigu painted houses, the Tongo hills and the Wa Naa's palace are all easier in the dry season. The laterite roads that link them hold together, the rivers are low, and a drive that would be a gamble in August is straightforward.

The cold surprises people. Harmattan nights in Bolgatanga and Navrongo can be genuinely cold, and rooms in the north are built for heat rather than for warmth. Guesthouse beds may have a sheet and nothing else. Ask for a blanket when you check in rather than at midnight.

The dryness is visible in the landscape as well as felt. The bush is pale and brittle, the baobabs are bare, and the smoke from bush burning drifts across the road in the late afternoon. It is a harsher, stranger and more memorable landscape than the green version, and photographs of it work best when you frame something close in the foreground.

A northern leg needs proper time. The drive from Accra to Tamale is a long day, and Mole is further again; doing it as a rushed add-on to a coastal trip is the sort of plan we generally talk clients out of. Our guided tour collections include multi-day journeys that take the north at a realistic pace.

What to actually pack

Pack for dryness and for cold nights, which is the opposite of what people expect to need in Ghana. A December or January trip to the north with only shorts and t-shirts is a genuinely uncomfortable trip.

• Heavy moisturiser or shea butter, and lip balm carried on your person
• Saline nasal spray and lubricating eye drops
• Glasses as well as contact lenses, plus sunglasses
• A fleece or warm layer for northern nights and early starts
• A light scarf or buff to pull over the nose and mouth on dusty roads
• Asthma or respiratory medication in full, including spares
• Microfibre cloths, a lens blower and sealed bags for camera gear
• A refillable water bottle, because you will drink more than you plan to

Clothes in light colours show dust less and stay cooler. Anything black or navy will look grey by the afternoon on a rural road, and white trainers are a decision you will regret in the north.

Our full Ghana packing list goes through the year-round essentials, including the documents and the medical items that matter regardless of season.

Pack for dryness and for cold nights. Nobody expects to need a fleece in Ghana.

Is it worth travelling in harmattan

Yes, for most trips, and for some trips it is the best window of the year. The honest accounting is that harmattan costs you long views and physical comfort, and gives you almost everything else.

What you gain is substantial. Humidity drops away, so the middle of the day becomes walkable rather than a slow ordeal. Nights are cool enough to sleep properly. Roads are dry and firm, which makes long drives and rural routes predictable. Wildlife viewing is at its annual peak. Forest trails are not slippery. Mosquito pressure, though never absent, is generally lower than in the wet months.

What you lose is the photographs you imagined and a few weeks of dry skin and irritated sinuses. For a photographer whose whole trip is landscape work, that is a serious cost and a different season may suit better. For almost everyone else it is an inconvenience managed with moisturiser.

The group I would think carefully about is anyone with significant asthma or a respiratory condition, along with very young children and frail older relatives, particularly for a northern itinerary. Harmattan will not stop the trip, but it should be discussed with a doctor and the itinerary should keep the northern leg short.

How we plan around harmattan

Ghana Travel & Tour plans trips around the season rather than pretending it is not happening. We will tell you honestly when a January photography trip is going to disappoint you, when a northern leg should be shortened, and when a domestic flight is worth swapping for a road transfer with a driver. We book flights and hotels, run Kotoka airport pickup with flight tracking and a driver waiting inside arrivals, and provide air-conditioned vehicles with drivers across all eight of our vehicle classes.
