Humidity comfort

DryComfortableHumidMuggyOppressiveMiserable

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 Colinas do Tocantins, how humid it feels changes dramatically over the year.

The more humid part of the year lasts 8.8 months, from around September 25 to June 18. The muggiest month is January, when the air feels humid, muggy or worse about 100% of the time.

The most comfortable stretch runs from around June 19 to September 24, and August is the most comfortable month — the air is dry or comfortable 49% 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.

Colinas do Tocantins receives about 5.3 kWh/m² a day of solar energy on average — bright — with a clear seasonal swing between 4.7 and 6.3 kWh/m².

The brighter stretch of the year lasts 4.7 months, from around Jul 2 to Nov 20. The brightest month is September, averaging about 6.2 kWh/m² (intense).

The dimmest month is March, down near 4.8 kWh/m² — roughly 23% less than the September peak.
