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 Sawang Daen Din, how humid it feels changes dramatically over the year.
The more humid part of the year lasts 7.8 months, from around March 9 to October 31. The muggiest month is April, when the air feels humid, muggy or worse about 99% of the time.

Average hourly UV index in Sawang Daen Din
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.

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.
Sawang Daen Din receives about 5.0 kWh/m² a day of solar energy on average — bright — with a clear seasonal swing between 4.2 and 6.1 kWh/m².
The brighter stretch of the year lasts 4.0 months, from around Jan 25 to May 25. The brightest month is April, averaging about 6.0 kWh/m² (intense).
The dimmest month is September, down near 4.4 kWh/m² — roughly 27% less than the April peak.
