Angola weather by month

In Luanda, 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 May 6 and lasts for 5.2 months, ending around October 11. The clearest month is June, when the sky is clear, mostly clear, or partly cloudy 85% of the time on average.

The cloudier part of the year begins around October 12 and lasts for 6.8 months, ending around May 5. The cloudiest month is April, 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.

Wind in Luanda is steady company: average speeds sit near 10 km/h — calm — in every month of the year, with no meaningful windy or calm season.

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.

Luanda receives about 5.0 kWh/m² a day of solar energy — bright — and it stays remarkably steady, holding between 4.5 and 5.7 kWh/m² all year. For solar panels, output here is a flat line, not a seasonal wave.
