Review long-term averages for temperature, precipitation, and humidity trends by month
Review atmospheric measurements for Kaw-Roura Marshland Nature Reserve based on NASA POWER climatology records from 1991 to 2020. These long-term averages provide a twelve-month overview of mean, minimum, and maximum temperatures alongside precipitation rates, wind speeds, and daylight hours sampled at a specific representative coordinate. Note that these values reflect long-term trends rather than current weather or forecasts for the entire reserve area.
