Long-term atmospheric averages derived from a representative coordinate for 1991 to 2020
Brush Island Nature Reserve in New South Wales provides a consistent climate profile across twelve months of observation. This dataset aggregates representative point measurements for average temperatures, daily precipitation rates, relative humidity, wind speed, and daylight hours based on the 1991 to 2020 climatology period. These values serve as a baseline for understanding the annual rhythm of the protected landscape without reflecting real-time weather fluctuations or park-wide variability.
