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.
Presidente Sarney 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 January, when it feels muggy, oppressive or miserable about 100% of the time. Even in January, the mildest month, the air is dry or comfortable only 0% of the time.

Average hourly UV index in Presidente Sarney
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.
Presidente Sarney receives about 5.0 kWh/m² a day of solar energy on average — bright — with a clear seasonal swing between 4.0 and 6.0 kWh/m².
The brighter stretch of the year lasts 5.5 months, from around Jul 17 to Dec 30. The brightest month is October, averaging about 6.0 kWh/m² (intense).
The dimmest month is April, down near 4.0 kWh/m² — roughly 33% less than the October peak.
