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.

See two months side by side and how much they differ. Both use the same 1991–2020 climate normals and NASA POWER data point as the table above, so they show typical conditions, not a forecast.
