Average Relative Humidity

Bureau of Meteorology Relative humidity (RH) is the quantity of moisture present in the air as a percentage of the quantity the air can really grasp. Warmer air has the capacity to grasp extra moisture than cooler air, which means that for a certain amount of atmospheric moisture, RH will be low if air is warm than it would be if the air is cool. Bureau of Meteorology can be noticed by evaluating the daily 9am maps (higher RH values) with the every days 3pm maps (lower RH values) for any month of the year.
