Average hourly UV index in Libertador General San Martín
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.
Libertador General San Martín receives about 4.7 kWh/m² a day of solar energy on average — bright — with a clear seasonal swing between 3.3 and 5.8 kWh/m².
The brighter stretch of the year lasts 6.6 months, from around Aug 14 to Mar 3. The brightest month is December, averaging about 5.7 kWh/m² (bright).
The dimmest month is May, down near 3.4 kWh/m² — roughly 40% less than the December peak.
