Temperature, precipitation, humidity, and wind averages based on a representative coordinate in Lower Saxony.
This climate profile provides a twelve-month overview of atmospheric conditions at Wurmberg, derived from NASA POWER datasets between 1991 and 2020. These figures represent long-term averages for a specific reference point at 357.57 meters in elevation, rather than current weather forecasts or site-wide conditions. Users can review data for average minimum and maximum temperatures, daily precipitation rates, relative humidity, wind speed, and seasonal daylight duration.

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.
