PRISM is a set of monthly, yearly, and single-event gridded data products of mean temperature and precipitation, max/min temperatures, and dewpoints, primarily for the United States. In-situ point measurements are ingested into the PRISM (Parameter elevation Regression on Independent Slopes Model) statistical mapping system.
Dew point temperature is a measure of moisture in the air and is contoured here every 5 degrees. When the dew point temperature is close to the temperature of the air, the air is nearly saturated. However, nearly saturated air is not always humid. Only when the temperatures reach above 70 degrees Fahrenheit and dew points rise nearly as high ...
The dew point is the temperature at which the air would be fully saturated (100% RH) and capable of forming dew (or frost, if it's cold enough). In the summertime, dew points are a useful measure of humidity (much more so than Relative Humidity). Dew points below 50 are dry, dew points between 50 and 65 are sticky but not unbearable and ...
maritime-Polar (mP): An air mass that brings chilly conditions, but has relatively high dew point temperatures (that are often close to the air temperature). mP air masses typically originate over high-latitude bodies of cold water, and in the United States, mP air masses regularly spread from the Pacific Ocean into the Pacific Northwest states ...

This map displays the observed dew point at a given point in time. The dew point is the temperature at which the air would be fully saturated (100% RH) and capable of forming dew (or frost, if it's cold enough). In the summertime, dew points are a useful measure of humidity (much more so than Relative Humidity).
Sep 20, 2023 · The highest dew point ever recorded, 95°F (35°C), was recorded at Dhahran, Saudi Arabia, on July 8, 2003. With an air temperature of 108°F (42°C), the heat index was 178°F (81°C). In looking at the basic climate regions around the world, we can see that there are some places where the weather is considered hot.
