Read all twelve months at a representative 0.01 m coordinate
Mili Atoll’s sampled mean temperature is 27.86 °C in February and 28.20 °C in November. Daily precipitation averages 5.84 mm in February and 9.05 mm in April, while wind speed measures 4.19 m/s in August and 7.74 m/s in February. These 1991–2020 NASA POWER values come from one near-sea-level coordinate and are not simultaneous observations across Mili’s long reef, islands, and lagoon.

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.
