Rock Islands Annual Climate Normals: Twelve Month Atmospheric and Meteorological Trends

Analyze the long term climate profile of Rock Islands through representative atmospheric data from 1991 to 2020. This documentation details monthly normals for mean, minimum, and maximum temperatures alongside precipitation rates, relative humidity, wind speed, and daylight hours. These measurements provide a consistent baseline for understanding the annual rhythm of the environment at a specific representative coordinate within the marine protected area.
