Average hourly UV index in Cachoeira do Sul
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.
Cachoeira do Sul receives about 4.5 kWh/m² a day of solar energy on average — bright — with a clear seasonal swing between 2.3 and 6.6 kWh/m².
The brighter stretch of the year lasts 5.8 months, from around Oct 1 to Mar 27. The brightest month is December, averaging about 6.6 kWh/m² (intense).
The dimmest month is June, down near 2.4 kWh/m² — roughly 64% less than the December peak.
