Chumash Heritage National Marine Sanctuary: Twelve Month Climate Normals and Atmospheric Data

Name: Chumash Heritage National Marine Sanctuary monthly climate normals
Creator: NASA POWER

Review the long-term climate profile for Chumash Heritage National Marine Sanctuary based on 1991 to 2020 NASA POWER measurements from a single representative coordinate at an elevation of 0.96 meters. Examine how monthly temperature, average daily precipitation, relative humidity, wind speed, and daylight duration shift throughout the calendar year. These records provide a consistent look at atmospheric averages rather than current weather or short-term forecasts for the marine protected area.
