Twelve month climatology based on NASA POWER representative point measurements
Review the long term atmospheric profile for Motuihe Island, covering the 1991 to 2020 climatology period. Data include monthly average minimum, mean, and maximum temperatures alongside precipitation rates, relative humidity, wind speed, and daylight hours. These measurements provide a consistent baseline for understanding the annual climate rhythm at this specific geographic coordinate in the Auckland region.
