Scan straight down any date to read that day across every measure at once; the score climbs highest around mid October to early April.

Humidity comfort
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 Allende, how humid it feels changes dramatically over the year.
The more humid part of the year lasts 5.8 months, from around April 26 to October 18. The muggiest month is August, when the air feels humid, muggy or worse about 98% of the time.
The most comfortable stretch runs from around October 19 to April 25, and January is the most comfortable month — the air is dry or comfortable 98% 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.

Average hourly UV index in Allende
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 July the burn window is concentrated in the middle of the day: about 8.5 hours a day reach index 3 (protection recommended), and 6.5 hours reach 6 or more. Mornings and late afternoons stay comparatively gentle year round.

Growing degree days
Growing degree days tally heat above 10°C: each day adds however many degrees its average temperature runs over that threshold, and cold days add nothing. Allende banks about 4,725 degree days a year, and the running total — which growers use to time plantings and predict maturity — climbs fastest around August.

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.
Allende receives about 5.1 kWh/m² a day of solar energy on average — bright — with a clear seasonal swing between 3.2 and 6.9 kWh/m².
The brighter stretch of the year lasts 6.3 months, from around Mar 17 to Sep 25. The brightest month is July, averaging about 6.8 kWh/m² (intense).
The dimmest month is December, down near 3.2 kWh/m² — roughly 53% less than the July peak.
