Annual patterns in temperature, precipitation, humidity, and daylight at a representative coordinate.
Annual atmospheric cycles for Three Islands Group National Park are characterized through representative-point measurements of average temperatures, daily precipitation rates, relative humidity, and wind speeds. These figures provide a consistent 30-year climatology baseline from 1991 to 2020. Understanding these seasonal trends helps define the long-term regional environment and provides a stable, data-driven reference for comparing month-to-month climate variance.
