Weather in August

August is the wettest month of the year in the Northern Mariana Islands with an average of 12.4" (315mm) of rainfall. It rains cats and dogs, yet there are clear, extended periods of bright sunshine that last up to 5 hours a day.
Day temperatures scale up to an average of 84°F (28.9°C), while nights register up to 75°F (23.9°C). The increase in humidity is the time for wearing sweatshirts and rain jackets for the remaining population on the islands.
Sightseeing tours often face challenges with the decrease in visibility due to cloud cover and rain. Beach and snorkeling activities are best on sunny days. The American Memorial Park in Garapan draws a considerable number of visitors during rainy days. Always carry rain protection in the wet season when outdoors. It is prudent to avoid August if a trip to the Northern Mariana Islands is on the radar.
