Dew Point

The dew point is the temperature to which air must be cooled for saturation (100% relative humidity) to occur, providing there is no change in water content. In simple terms, it’s the temperature at which dew can form. When the dew point temperature falls below freezing, it is often called the frost point, as frost is more likely to form at these temperatures. The dew point is an important aspect of weather forecasts as it is a measure of atmospheric moisture. It’s particularly significant in weather conditions involving precipitation, humidity, and visibility. Higher dew points indicate higher moisture content in the air, which can contribute to a feeling of stickiness or discomfort on hot days.
