Detailed representative-point climatology of annual temperature, precipitation, and daylight patterns.
This climate profile provides a twelve-month record of average temperature, precipitation, relative humidity, wind speed, and daylight hours for Réserve naturelle régionale d'Errota Handia. Measurements derive from NASA POWER satellite data for the 1991 to 2020 climatology period at a single representative coordinate. These statistics offer a baseline for understanding the annual atmospheric cycle at the reserve, distinct from daily weather forecasts or local microclimate variations found across the protected landscape.
