The dew point is the temperature at which air becomes saturated with moisture, leading to the formation of dew. When the air cools to this temperature, it can no longer hold all the water vapor present, causing condensation. This is why dew often forms on grass and other surfaces during the night when temperatures drop. Understanding the dew point is important in meteorology and can help predict weather conditions. A higher dew point indicates more moisture in the air, which can lead to a muggy feeling and increased chances of precipitation. Conversely, a lower dew point suggests drier air and clearer skies.
