Detailed representative-point climatology covering temperature, precipitation, and wind speeds
Review twelve-month climate averages for Whakanewha Regional Park, derived from NASA POWER measurements between 1991 and 2020. Data includes mean, minimum, and maximum temperatures along with average daily precipitation, humidity levels, wind speed, and daylight hours. These figures provide a baseline for understanding the long-term annual atmospheric rhythm at a representative park location rather than reflecting current weather conditions.

Analyzing long-term average temperature ranges alongside monthly precipitation rates for targeted protected-area coordination
Track monthly temperature bounds, average daily precipitation, humidity, wind speed, and calculated daylight across the calendar year.
