Review long-term climate normals spanning temperature, precipitation, and daylight duration.
Joyce Kilmer-Slickrock Wilderness climate normals provide a twelve-month overview based on NASA POWER data from 1991 to 2020 at a fixed representative coordinate. These records detail monthly average temperature, minimum and maximum ranges, daily precipitation rates, relative humidity, wind speed, and daylight hours. The values serve as a baseline for understanding the annual atmospheric cycle in this North Carolina protected area rather than representing localized microclimates or current daily weather forecasts.
