Twelve-month atmospheric normals derived from representative coordinate data in Western Australia
Annual climate cycles at Charles Darwin Reserve provide a consistent view of regional atmospheric patterns. These records detail monthly average minimum and maximum temperatures, daily precipitation rates, relative humidity, wind speed, and daylight hours based on 1991 to 2020 NASA POWER data. Measurements represent long-term climatology at a single point rather than real-time conditions, allowing for accurate year-round comparison of local meteorological trends.

See two months side by side and how much they differ. Both use the same 1991–2020 climate normals and NASA POWER data point as the table above, so they show typical conditions, not a forecast.
