Monthly averages for temperature, precipitation, wind, and daylight at a representative coordinate.
Comprehensive climatology for Sintra-Cascais Natural Park based on NASA POWER measurements collected from 1991 to 2020. Monthly tables provide standardized data for mean, minimum, and maximum temperatures alongside precipitation, relative humidity, wind speed, and daylight duration. These metrics represent fixed atmospheric conditions at a specific elevation point and reflect annual climate rhythm rather than daily weather or seasonal forecasts.
