Twelve month analysis of temperature, precipitation, and atmospheric conditions at a representative coordinate.
Cabbage Tree Island (John Gould Nature Reserve) climate data provides a twelve month profile based on NASA POWER records from 1991 to 2020. This analysis focuses on monthly climate normals including mean, minimum, and maximum temperatures alongside precipitation rates, relative humidity, wind speed, and daylight duration. These measurements reflect conditions at a single representative elevation of 40.29 meters and do not account for microclimate variations across the entire reserve.
