Twelve-month average analysis of temperature, humidity, wind, and rainfall patterns
This profile presents long-term climate averages for Mare de Lassouri, derived from NASA POWER measurements between 1991 and 2020 at a specific representative coordinate. Records include monthly mean, minimum, and maximum temperatures alongside average daily precipitation, relative humidity, wind speed, and daylight hours. Observations reflect specific point-based climatology rather than localized microclimates or current daily weather forecasts.
Comparing twelve months of average minimum, mean, and maximum temperatures alongside average daily precipitation
Analyze long-term temperature bounds, average daily precipitation, humidity, wind speed, and calculated daylight across the calendar year.

See two months side by side and how much they differ. Both use the same 1991–2020 climate normals and NASA POWER data point as the table above, so they show typical conditions, not a forecast.
