Nicaragua weather by month

In Managua, 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 November 12 and lasts for 5.6 months, ending around May 1. The clearest month is February, when the sky is clear, mostly clear, or partly cloudy 90% of the time on average.

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.

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.

Managua receives about 5.6 kWh/m² a day of solar energy on average — bright — with a clear seasonal swing between 4.7 and 6.7 kWh/m².

The brighter stretch of the year lasts 3.6 months, from around Jan 28 to May 18. The brightest month is April, averaging about 6.6 kWh/m² (intense).

The dimmest month is October, down near 4.7 kWh/m² — roughly 29% less than the April peak.
