Detailed atmospheric records including temperature, precipitation, and daylight for annual analysis
Piopiotahi (Milford Sound) Marine Reserve climate profiles provide essential long-term averages for temperature, humidity, wind speed, and precipitation rates. Data is derived from NASA POWER measurements for a representative coordinate at 643.19 meters elevation, covering the 1991 to 2020 climatology period. These monthly values illustrate the persistent atmospheric patterns throughout the calendar year, supporting precise geographic comparison and landscape research.
