Long term atmospheric averages for a representative coordinate at 27.7 meters in elevation.
Review twelve months of consistent climatological data for Southern Kangaroo Island Marine Park based on the 1991 to 2020 NASA POWER dataset. This profile features month by month averages for temperature, precipitation, humidity, wind speed, and daylight hours. These records offer a precise look at local atmospheric patterns without accounting for short term weather shifts or wider geographic variation across the marine protected area.

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.
