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 Balneário Gaivota, how humid it feels changes dramatically over the year.

The more humid part of the year lasts 6.5 months, from around October 18 to May 4. The muggiest month is March, when the air feels humid, muggy or worse about 94% of the time.

The most comfortable stretch runs from around May 5 to October 17, and August is the most comfortable month — the air is dry or comfortable 76% of the time.

Average wind speed through the year, banded into plain-language speed zones so a number reads as 'breezy' or 'calm' without knowing the scale.

This is the average sustained wind speed at the standard 10 metres above open ground — the steady flow a weather station reports, not the sharper gusts that come and go, which can run half again as fast. It's the number that says whether a place is generally breezy or calm.

Across the year, average wind speed in Balneário Gaivota is typically light breeze, near 17 km/h, and varies moderately with the seasons.

The windier part of the year lasts 5.0 months, from around Jul 30 to Dec 28. The windiest month is September, averaging about 20 km/h (light breeze).

Average hourly UV index in Balneário Gaivota

LowModerateHighVery highExtreme

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.

UV falls off far faster than brightness as the sun drops, so even in January the burn window is concentrated in the middle of the day: about 9 hours a day reach index 3 (protection recommended), and 7 hours reach 6 or more. Mornings and late afternoons stay comparatively gentle year round.

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.

Balneário Gaivota receives about 4.7 kWh/m² a day of solar energy on average — bright — with a clear seasonal swing between 2.6 and 6.6 kWh/m².

The brighter stretch of the year lasts 5.8 months, from around Oct 2 to Mar 28. The brightest month is December, averaging about 6.6 kWh/m² (intense).

The dimmest month is June, down near 2.7 kWh/m² — roughly 59% less than the December peak.
