September weather forecast
Micronesia

September in Micronesia represents the height of the tropical wet season and is typically the rainiest month of the year. It is also the period when the region is most vulnerable to typhoons and other severe weather events.

The average temperatures during September range from 28°C (82.4°F) to 31°C (87.8°F), similar to those experienced in August. This consistent warmth, spread across the islands of Pohnpei, Kosrae, and the northern outer islands, contributes to the prevailing humidity during this period.

Rainfall in September often exceeds the high levels seen in the preceding months. The average precipitation across the country varies from 450mm (17.72") to 500mm (19.69"), although localized amounts can be considerably higher. Pohnpei, with its unique climatic conditions, often records rainfall well above the national average.

When compared to August, September maintains similar temperature ranges but experiences a marked increase in rainfall. Given its position in the peak of the typhoon season, September carries a heightened risk of typhoons and other severe weather phenomena. The combination of high temperatures, heavy rainfall, and the potential for extreme weather events encapsulates the climate characteristics of September in Micronesia.
