Twelve-month climatology based on representative coordinate data for Nevada wilderness terrain
The climate profile for Fortification Range Wilderness provides a consistent look at long-term atmospheric patterns using 1991 to 2020 NASA POWER datasets. Each monthly metric covers average minimum and maximum temperatures, daily precipitation rates, relative humidity, wind speed, and daylight hours measured at a representative elevation of 2001 meters. These historical records offer a clear reference for the annual environmental rhythm of the landscape, distinct from short-term weather forecasts or current conditions.

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.
