Monthly analysis of temperature, precipitation, humidity, wind, and daylight averages
Examine the twelve-month climate profile for Great Australian Bight Marine Park, derived from NASA POWER atmospheric data for a single representative coordinate. These records present long-term monthly averages for minimum and maximum temperatures, daily precipitation rates, relative humidity, wind speed, and daylight hours from 1991 through 2020. Understanding these atmospheric patterns provides essential context for the environment of this significant marine protected area.
