Share of days at each humidity comfort level, based on the dew point — the measure that tracks how muggy it actually feels.

A low dew point feels dry and crisp; a high one feels sticky and oppressive no matter the reading on a humidity gauge.

Laranjal do Jari 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.

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.

Laranjal do Jari receives about 4.8 kWh/m² a day of solar energy on average — bright — with a clear seasonal swing between 3.8 and 6.3 kWh/m².

The brighter stretch of the year lasts 5.2 months, from around Jul 20 to Dec 23. The brightest month is October, averaging about 6.2 kWh/m² (intense).
