September 6, 2026
These two charts show the temperature and the moisture content of the air (as dew point temperature) for a selection of worldwide locations in the third month of meteorological summer this year

The higher the dew point temperature, the more moisture is in the air.

The combination of high air temperature and high dew point temperature is also an easy way to assess relative disease risk for cool-season grasses.
