Cape Coast weather in December

Ghana's forum notes that this stretch of coast, Cape Coast included, runs extremely hot through February and March, with the destination's own numbers backing that up. It's also the calm-ish window before the main rains: Ghana's coast gets two rainy seasons, roughly March through June and again September into October, which puts February just ahead of the first one starting. Expect a real but not overwhelming chance of rain and generally hazy, hot conditions rather than the heavier downpours the coming rainy season brings.

Forum posters describe July and August as the coolest months of the year along Ghana's coast, with temperatures typically in the 70s-80sF rather than the 90-plus heat common the rest of the year. Posters are consistent that August sits toward the tail end of the rainy season, meaning some rain most days is likely, but posters describe it as intermittent rather than constant or torrential - a real contrast to what travelers might expect from a rainy-season label, provided the visit stays along the coast rather than heading north. Posters generally frame June through August as a genuinely comfortable window for coastal Ghana, with the cooler temperatures and manageable, non-relentless rain making Cape Coast and nearby Anomabo workable for a beach-and-history-focused stay.
