Twelve month analysis of temperature, precipitation, and wind patterns from 1991 to 2020
Wisconsin Shipwreck Coast National Marine Sanctuary exhibits distinct annual climate cycles defined by long term atmospheric measurements. This analysis provides monthly averages for air temperature, precipitation rates, relative humidity, wind speed, and daylight hours derived from representative NASA POWER data. These figures characterize regional climatology between 1991 and 2020, offering a stable reference for environmental conditions at a single coordinate rather than real time meteorological forecasts.
