Long term atmospheric patterns featuring temperature, wind, and precipitation measurements
Detailed monthly climate profiles for Val Marie Reservoir Migratory Bird Sanctuary represent a singular geographic point based on 1991 to 2020 NASA POWER data. These statistics detail the annual rhythm of average minimum, mean, and maximum temperatures alongside relative humidity, average daily precipitation rates, wind speeds, and daylight hours. Such metrics provide a scientific baseline for understanding local environmental conditions without reflecting real time weather or current meteorological forecasts.
