Long-term monthly averages covering temperature, precipitation, humidity, wind, and daylight duration.
The climate profile for Mangere Island presents monthly averages calculated from a representative coordinate over the 1991 to 2020 climatology period. These figures detail mean, minimum, and maximum temperatures alongside precipitation rates, relative humidity, average wind speed, and daily daylight hours. By analyzing these data points, researchers and geography enthusiasts can compare seasonal atmospheric fluctuations within this nature reserve without conflating long-term trends with current daily weather forecasts or local microclimates.
