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.

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.
Viçosa do Ceará receives about 5.7 kWh/m² a day of solar energy on average — bright — with a clear seasonal swing between 4.8 and 6.9 kWh/m².
The brighter stretch of the year lasts 5.1 months, from around Jul 25 to Dec 26. The brightest month is October, averaging about 6.9 kWh/m² (intense).
The dimmest month is April, down near 4.8 kWh/m² — roughly 29% less than the October peak.
