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.
In Al Mash‘ilīyah, the air stays dry or comfortable essentially all year. Even in April, the muggiest month, it feels humid or worse only about 2% of the time — humidity is not something you need to plan around here.

Average hourly UV index in Al Mash‘ilīyah
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 April 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.
Al Mash‘ilīyah receives about 6.5 kWh/m² a day of solar energy on average — intense — with a clear seasonal swing between 5.4 and 7.6 kWh/m².
The brighter stretch of the year lasts 7.3 months, from around Mar 5 to Oct 13. The brightest month is May, averaging about 7.5 kWh/m² (intense).
The dimmest month is December, down near 5.4 kWh/m² — roughly 28% less than the May peak.
