Météo à Cotonou en juin

Forum posters describe Lagos, Nigeria weather as usually hot and humid with tropical rain that arrives heavy rather than as a light drizzle, and one resort review specifically warns the property isn't well suited to a rainy-season visit given how operations there are affected once the rain sets in. Posters generally note temperatures well over 90F (32C+) under scorching sun as typical, with air conditioning genuinely valued indoors given how few outdoor spaces offer any relief. Given the limited destination-specific detail for June exactly, this note leans on that broader pattern: June sits within Lagos's rainy season, so expect frequent, heavy downpours layered on top of persistent heat and humidity, with indoor plans and flexible scheduling around storms the more reliable approach than counting on dry days.

Forum posters describe Benin's coast as having two rainy seasons, April through July and September through mid-October, both generally recommended to avoid given unstable weather and a rougher sea. Posters instead point to late December through mid-February as the better overall window for a Cotonou visit. Given July falls within the first of those two rainy stretches, posters' framing implies hot, humid conditions with substantial rain and choppier coastal waters typical of this part of the West African coast. Posters generally rate July as one of Cotonou's weaker weather windows, with the December-February dry stretch a clearly better-regarded alternative.

Forum posters describe the Harmattan winds - dry Saharan air carrying a lot of dust - as a defining feature of this stretch of the West African coast from roughly late December through mid-February, meaning January sits squarely within that hazy, dust-laden but comparatively dry window. Posters specifically flag February through April as the hottest months of the year here, implying January itself, while still warm and humid on the coast, runs a touch more moderate than the peak heat still to come. Posters generally recommend light, breathable clothing regardless of the Harmattan's dry-air reputation, since the dust itself - rather than rain - is the main practical annoyance travelers report for a January visit to Cotonou.
