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

Average hourly UV index in Santo Antônio da Patrulha
Modeled clear-sky UV for every hour of every day — when in the day sun protection actually matters.
The whole year hour by hour: each column is a day, each row an hour, and the color is the modeled clear-sky UV index — the midday peak scaled down as the sun sits lower in the sky. Darker overlays mark night, lighter ones the civil-twilight hours around sunrise and sunset.

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.
Santo Antônio da Patrulha receives about 4.4 kWh/m² a day of solar energy on average — bright — with a clear seasonal swing between 2.4 and 6.4 kWh/m².
The brighter stretch of the year lasts 5.9 months, from around Oct 1 to Mar 28. The brightest month is December, averaging about 6.4 kWh/m² (intense).
The dimmest month is June, down near 2.5 kWh/m² — roughly 61% less than the December peak.
