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 Nova Alvorada do Sul, how humid it feels changes dramatically over the year.

The more humid part of the year lasts 7.0 months, from around October 2 to May 2. 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 May 3 to October 1, and August is the most comfortable month — the air is dry or comfortable 83% 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.

Nova Alvorada do Sul receives about 5.1 kWh/m² a day of solar energy on average — bright — with a clear seasonal swing between 3.5 and 6.2 kWh/m².

The brighter stretch of the year lasts 7.0 months, from around Sep 1 to Apr 1. The brightest month is December, averaging about 6.1 kWh/m² (intense).

The dimmest month is June, down near 3.6 kWh/m² — roughly 42% less than the December peak.
