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.

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.

Djibouti receives about 5.8 kWh/m² a day of solar energy on average — bright — with a clear seasonal swing between 4.9 and 6.6 kWh/m².

The brighter stretch of the year lasts 3.3 months, from around Feb 28 to Jun 6. The brightest month is May, averaging about 6.4 kWh/m² (intense).

The dimmest month is January, down near 4.9 kWh/m² — roughly 23% less than the May peak.
