Ivory Coast weather by month

In Abidjan, the average share of the sky covered by clouds shows significant seasonal variation over the course of the year.

The clearer part of the year begins around September 30 and lasts for 5.4 months, ending around March 12. The clearest month is January, when the sky is clear, mostly clear, or partly cloudy 67% of the time on average.

The cloudier part of the year begins around March 13 and lasts for 6.6 months, ending around September 29. The cloudiest month is May, when it is overcast or mostly cloudy 78% of the time.

This is the average sustained wind speed at the standard 10 metres above open ground — the steady flow a weather station reports, not the sharper gusts that come and go, which can run half again as fast. It's the number that says whether a place is generally breezy or calm.

Across the year, average wind speed in Abidjan is typically light breeze, near 14 km/h, and varies moderately with the seasons.

The windier part of the year lasts 4.0 months, from around Jun 12 to Oct 10. The windiest month is July, averaging about 16 km/h (light breeze).

The calmer part of the year runs from around Oct 11 to Jan 24, with November the calmest month at about 11 km/h.

Solar energy is how much sunlight actually reaches the ground each day, measured in kilowatt-hours per square metre (kWh/m²) — the combined effect of how long the sun is up, how high it climbs, and how much cloud gets in the way. It's the raw fuel a solar panel has to work with: for scale, 1 kWh/m² a day is dim and wintry, while 7+ is desert-bright.

Abidjan receives about 5.0 kWh/m² a day of solar energy — bright — and it stays remarkably steady, holding between 4.3 and 5.8 kWh/m² all year. For solar panels, output here is a flat line, not a seasonal wave.
