Ecuador weather by month

In Quito, the average share of the sky covered by clouds shows significant seasonal variation over the course of the year.

The clearer part of the year begins around June 5 and lasts for 3.6 months, ending around September 22. The clearest month is August, when the sky is clear, mostly clear, or partly cloudy 30% of the time on average.

The cloudier part of the year begins around September 23 and lasts for 8.4 months, ending around June 4. The cloudiest month is March, when it is overcast or mostly cloudy 99% of the time.

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 Quito is steady company: average speeds sit near 4 km/h — calm — in every month of the year, with no meaningful windy or calm season.

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.

Quito receives about 4.4 kWh/m² a day of solar energy — bright — and it stays remarkably steady, holding between 4.2 and 4.8 kWh/m² all year. For solar panels, output here is a flat line, not a seasonal wave.
