Central African Republic weather by month

In Bangui, 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 November 18 and lasts for 3.5 months, ending around March 3. The clearest month is December, when the sky is clear, mostly clear, or partly cloudy 55% of the time on average.

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 Bangui is typically calm, near 6 km/h, and varies little with the seasons.

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.

Bangui receives about 5.4 kWh/m² a day of solar energy — bright — and it stays remarkably steady, holding between 4.8 and 6.1 kWh/m² all year. For solar panels, output here is a flat line, not a seasonal wave.
