Gray's Reef National Marine Sanctuary Monthly Climate Normals, 1991 to 2020 Data Profile

Name: Gray's Reef National Marine Sanctuary monthly climate normals
Creator: NASA POWER

The climate profile provides a comprehensive twelve-month view of long-term weather averages for a representative coordinate within Gray's Reef National Marine Sanctuary. Captured from 1991 to 2020 NASA POWER data, this record focuses on monthly mean temperature, average minimums and maximums, daily precipitation rates, relative humidity, wind speed, and daylight duration. These measurements establish a baseline for understanding the annual atmospheric patterns at this marine protected area, distinct from seasonal forecasts or daily weather reports.
