Long-term atmospheric patterns featuring temperature, precipitation, and daylight data
Annual climate averages for Sea Wolf Island National Wildlife Area derived from 1991 to 2020 NASA POWER datasets. Measurements reflect a specific representative coordinate at 114.84 meters elevation. Data includes average monthly minimum and maximum temperatures, mean precipitation rates, relative humidity, wind speed, and daylight hours to characterize long-term atmospheric cycles.
Analysis of average monthly minimum, mean, and maximum temperatures alongside daily precipitation rates
Analyze long-term temperature bounds, average daily precipitation, humidity, wind, and calculated daylight across 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.
