Long term atmospheric averages based on NASA POWER measurements from 1991 to 2020
Annual climatic patterns for Sint Eustatius National Marine Park are analyzed through representative-point measurements, covering monthly averages for minimum and maximum temperatures, daily precipitation rates, and relative humidity. These records provide a consistent look at environmental conditions like wind speed and daylight hours, reflecting long term trends rather than current weather or forecasts. Each measurement reflects the baseline climatology for a singular coordinate point at an elevation of 3.25 meters.
