Annual patterns in daylight, humidity, and atmospheric conditions at a representative park location
These monthly climate normals provide a representative overview of the atmospheric conditions at Avon Valley National Park. The data presents long-term averages for temperature, daily precipitation, wind speed, relative humidity, and daylight hours, calculated from 1991 to 2020 NASA POWER measurements. These records reflect conditions at a single point and do not account for microclimates across the entire park landscape.
