Detailed average temperature, precipitation, and wind measurements for a representative coordinate location
Explore the multi-decade climate record for Sleeping Bear Dunes National Lakeshore, derived from NASA POWER measurements for the period between 1991 and 2020. The provided data profiles the annual rhythm of the area through monthly averages for minimum, mean, and maximum temperatures, alongside daily precipitation rates, relative humidity, wind speed, and daylight hours. Each value represents climatological patterns at a specific park coordinate rather than current weather or forecasts.
