Long-term monthly climate normals spanning temperature, precipitation, wind, and daylight hours.
The climate profile provides a technical overview of long-term atmospheric variables at a representative coordinate within Apalachicola National Estuarine Research Reserve. Based on NASA POWER data from 1991 to 2020, the data tracks monthly trends in mean, minimum, and maximum temperatures alongside precipitation rates, relative humidity, wind speed, and daylight duration. These records offer a consistent annual baseline for understanding the environmental conditions characteristic of this protected area in Florida.
