Round Island Nature Reserve Climate Normals: Monthly Temperature, Precipitation, and Atmospheric Patterns

The climate profile for Round Island presents monthly averages for temperature, precipitation, humidity, wind, and daylight hours from 1991 to 2020. Data reflects specific representative-point climatology rather than current daily weather or island-wide variations. Monthly observations trace the annual cycle of thermal patterns and moisture levels to provide a consistent basis for understanding the local environment.
