Twelve-month climate dataset for the Kermadec Islands based on representative-point measurements

Kermadec Islands Climate Normals: Annual Patterns of Temperature and Atmospheric Variables

Climate records for the Kermadec Islands provide an annual overview of temperature, precipitation, humidity, wind speed, and daylight duration. These figures represent long-term averages for the period 1991 to 2020 at a specific coordinate within the nature reserve. By tracking monthly fluctuations, the data enables an understanding of annual atmospheric cycles rather than current daily conditions or broader regional weather trends.
