Scan straight down any date to read that day across every measure at once; the score climbs highest around late May to late September.

Humidity comfort
Share of days at each humidity comfort level, based on the dew point — the measure that tracks how muggy it actually feels.
Humidity comfort is graded by the dew point — the temperature at which the air would be fully saturated — because it tracks how muggy it actually feels far better than relative humidity does. A low dew point feels dry and crisp; a high one feels sticky and oppressive no matter the reading on a humidity gauge.
Garissa is humid all year round — on a typical day the air feels at least humid, and there is no real dry season to wait for.
The stickiest month is March, when it feels muggy, oppressive or miserable about 88% of the time. Even in July, the mildest month, the air is dry or comfortable only 2% of the time.

Wind
Average wind speed through the year, banded into plain-language speed zones so a number reads as 'breezy' or 'calm' without knowing the scale.
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 Garissa is typically light breeze, near 16 km/h, and varies a lot with the seasons.
The windier part of the year lasts 6.1 months, from around Apr 21 to Oct 23. The windiest month is July, averaging about 23 km/h (breezy).

Average hourly UV index in Garissa
Modeled clear-sky UV for every hour of every day — when in the day sun protection actually matters.
The whole year hour by hour: each column is a day, each row an hour, and the color is the modeled clear-sky UV index — the midday peak scaled down as the sun sits lower in the sky. Darker overlays mark night, lighter ones the civil-twilight hours around sunrise and sunset.
UV falls off far faster than brightness as the sun drops, so even in March the burn window is concentrated in the middle of the day: about 8.5 hours a day reach index 3 (protection recommended), and 6.5 hours reach 6 or more. Mornings and late afternoons stay comparatively gentle year round.

Solar energy
Average daily shortwave solar energy reaching the ground, banded into brightness zones so the number means something at a glance.
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.
Garissa receives about 5.7 kWh/m² a day of solar energy on average — bright — with a clear seasonal swing between 4.7 and 6.7 kWh/m².
The brighter stretch of the year lasts 4.5 months, from around Dec 10 to Apr 26. The brightest month is February, averaging about 6.7 kWh/m² (intense).
The dimmest month is July, down near 4.7 kWh/m² — roughly 30% less than the February peak.
