Long-term atmospheric patterns featuring representative data from 1991 through 2020
The climate profile for Wainuiomata Regional Park provides twelve months of atmospheric averages, derived from NASA POWER measurements at a representative coordinate. This dataset includes mean, minimum, and maximum temperatures alongside average daily precipitation, humidity, wind speeds, and daylight duration. These records serve as long-term benchmarks for understanding the annual meteorological rhythm of this Wellington Region landscape without incorporating daily forecasts or visitor conditions.
