Port Royal National Park Annual Climate Normals: Monthly Temperature, Precipitation, and Wind Data

Monthly climate data for Port Royal National Park presents long-term averages for temperature, precipitation rates, relative humidity, wind speed, and daylight hours. Derived from NASA POWER records covering 1991 to 2020, these measurements provide a consistent baseline for understanding annual atmospheric patterns. The data reflects a single representative coordinate within the park rather than the full range of microclimates across the entire protected landscape.
