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 Salamá, how humid it feels changes dramatically over the year.

The more humid part of the year lasts 6.2 months, from around May 4 to November 8. The muggiest month is September, when the air feels humid, muggy or worse about 95% of the time.

The most comfortable stretch runs from around November 9 to May 3, and February is the most comfortable month — the air is dry or comfortable 97% of the time.

Wind

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.

Wind in Salamá is steady company: average speeds sit near 5 km/hcalm — in every month of the year, with no meaningful windy or calm season.

Best time to visit Salamá

TravelBeach/poolTemperatureCloudsPrecipitation

To characterize how pleasant the weather is in Salamá throughout the year, we compute two travel scores — one for general sightseeing, one for beach and pool weather.

Around mid March, Salamá is still near the tail of its best-weather window — great conditions with the peak-season crowds already thinning.

Inferred from the travel-score curve; month-by-month visitor numbers are a planned addition.

The travel score favors clear, rainless days with daytime highs between 18°C and 28°C. Based on this score, the best time of year to visit Salamá for general outdoor tourist activities is from mid November to late March, with a peak score in the second week of January.

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 April 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.

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.

Salamá receives about 5.2 kWh/m² a day of solar energy on average — bright — with a clear seasonal swing between 4.2 and 6.3 kWh/m².

The brighter stretch of the year lasts 7.0 months, from around Feb 14 to Sep 15. The brightest month is April, averaging about 6.2 kWh/m² (intense).

The dimmest month is November, down near 4.2 kWh/m² — roughly 32% less than the April peak.
