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 San Lorenzo Acopilco, the air stays dry or comfortable essentially all year. Even in May, the muggiest month, it feels humid or worse only about 0% of the time — humidity is not something you need to plan around here.

Average hourly UV index in San Lorenzo Acopilco
Modeled clear-sky UV for every hour of every day — when in the day sun protection actually matters.

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.
San Lorenzo Acopilco receives about 5.7 kWh/m² a day of solar energy on average — bright — with a clear seasonal swing between 4.9 and 6.9 kWh/m².
The brighter stretch of the year lasts 4.3 months, from around Feb 11 to Jun 20. The brightest month is April, averaging about 6.9 kWh/m² (intense).
The dimmest month is December, down near 4.9 kWh/m² — roughly 29% less than the April peak.
