Forum posters generally name January through March, alongside September through December, as favorable weather windows for Ghana, with the main rainy season running roughly March or April through August. Posters flag the December-January Harmattan winds as a distinct feature of the earlier part of this dry stretch, bringing dry, dusty conditions from the Sahara, though by February that effect should be easing. Posters discussing nearby Cape Coast note a February-March visit felt extremely hot, suggesting heat rather than rain is the more relevant discomfort factor for this window along Ghana's coast. Posters generally rate February as one of the better, drier months to visit Accra, with heat and humidity the main planning consideration rather than rain.

August sits at the end of Ghana's rainy season — roughly March or April through August — and the forum's framing is that you will likely get rain at some point on most days, but it is neither constant nor torrential. The record backs the frequency: about sixteen wet days. Temperatures barely move, near 27°C by day and 23 overnight, with humidity the forum puts at 70–80%, and the thermometer drops only three or four degrees around a downpour. You will not be sunbathing much. The dry, dusty harmattan that defines northern Ghana's winter runs December to March — the opposite end of the year entirely.
