Twelve month analysis of temperature, precipitation, humidity, wind, and daylight norms.
Detailed climate normals for Hawea (Clio Rocks) Marine Reserve, derived from NASA POWER measurements spanning 1991 to 2020 at a representative coordinate at 580.73 meters. Data focuses on annual rhythm patterns of temperature, average daily precipitation, relative humidity, wind speed, and daylight duration. These records provide a consistent baseline for analyzing the atmospheric conditions within the marine protected area boundaries throughout the calendar year.

See two months side by side and how much they differ. Both use the same 1991–2020 climate normals and NASA POWER data point as the table above, so they show typical conditions, not a forecast.
