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.
Comparing long term thermal variations alongside daily precipitation rates through the year
Analyze twelve months of average temperature bounds, daily precipitation rates, and calculated daylight.

See two months side by side and how much they differ. Both use the same 1991–2020 climate normals and NASA POWER data point as the table above, so they show typical conditions, not a forecast.
