Ghana weather, month by month

How Ghana's weather works

Ghana sits just north of the equator, so it is warm throughout the year — usually between 25 and 33C — and it is humidity and rainfall, not temperature, that define the seasons. The country has two broad climate zones. The south, including Accra and the coast, has two rainy seasons and two dry spells; the north, around Tamale and Mole, has a single rainy season from roughly May to October and a long dry season the rest of the year.

Layered on top is the harmattan, a dry, dusty wind that blows off the Sahara from late December into February, lowering humidity and softening the light with a distinctive haze. It cools the mornings, dries the air and, in the north especially, can turn the horizon a pale, dusty gold.

Once you understand this rhythm, choosing dates becomes simple, because you are really choosing between reliable sun, lush greenery or the cooler harmattan light. Pair this guide with our best time to visit Ghana and, for what to pack in each season, our Ghana packing list.

December to March: the dry season

December opens the main dry season and the festive rush of Detty December. Days are warm and largely rainless; late in the month the harmattan arrives, bringing cooler, hazier mornings. January is many people's favourite month — dry, comfortable and pleasantly cool after dark, though the Saharan haze can mute distant views.

February stays dry as the harmattan eases and the heat begins to build, while March is typically the hottest month, increasingly humid and sticky as the first storms begin to threaten on the horizon. Northern Ghana is bone-dry through this whole stretch, which is prime time for wildlife at Mole as animals gather at the shrinking waterholes and the thinner bush makes them far easier to spot.

This is peak visiting season for good reason. Explore the parks with our Mole safari guide and Kakum canopy walk guide.

April to August: the major rains and a break

April marks the start of the southern major rains, tending to arrive as dramatic, refreshing afternoon and evening thunderstorms rather than the grey, all-day drizzle familiar in Europe. May and June are the wettest months in the south, with June often the peak; humidity climbs, the air smells of wet earth, and the landscape turns a saturated green. July stays wet but begins to ease off in places, particularly along the coast.

Then comes a welcome surprise: August brings the "little dry season", a cooler, drier and often overcast break in the southern rains that many locals quietly love. Temperatures dip, the humidity relaxes, and it can be a genuinely good, low-crowd time to travel the coast and the cities.

The far north keeps raining through this period as its single wet season runs from May into October, so a southern-focused itinerary makes sense in these months. Even so, showers rarely last all day — see our Ghana beaches guide for coast that still shines between the storms.

September to November: minor rains and drying out

September and October bring the south's shorter, minor rainy season — less intense than the major rains but still bringing regular showers and lush scenery. Temperatures are comfortable and the crowds are thin, so value is good if you do not mind a passing downpour.

By November the rains taper off across the south and the country begins drying out ahead of the festive peak. It is a lovely, green, uncrowded month with increasingly reliable sunshine and comfortable temperatures — one of the year's most underrated windows for visitors who want good weather without December's prices and crowds.

This is a fine time for the coast and the Volta Region. Our Volta Region and Wli Falls guide shows the waterfalls at their fullest just as the skies clear.

Choose your month and plan your trip

In short, there is no bad time to visit Ghana — only different flavours. Choose December to March for reliable dry-season sun and the best wildlife viewing at Mole, August or November for green landscapes, waterfalls in full flow and excellent value, and expect warm, welcoming weather whenever you come. The rains never last long enough to spoil a well-planned trip.

Whatever your dates, a little local planning ensures you catch the best of the weather and route around the rains. For a broader steer, read why to visit Ghana and check how many days in Ghana you will need.
