Long-term atmospheric averages for temperature, precipitation, humidity, and daylight cycles
Detailed twelve-month climate analysis for Nguthungulli Julian Rocks Nature Reserve, based on NASA POWER data from 1991 to 2020. This profile presents representative monthly averages for minimum and maximum temperatures, daily precipitation rates, relative humidity, wind speed, and daylight hours at a specific reserve coordinate. These figures provide a standardized climatology record, distinct from real-time weather forecasts or short-term meteorological observations.
