Long-term environmental averages based on a representative coordinate in Nevada.
Review twelve-month climate patterns for Jimbilnan Wilderness, including average temperatures, daily precipitation rates, relative humidity, wind speeds, and daylight hours. These records reflect long-term meteorological averages from 1991 to 2020 at a representative site. Please note that data represents specific-point climatology rather than whole-park conditions or current 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.
