Weather in May

May is the last month of the dry season in Guam, with the average temperatures in the 77°F (25°C) to 88°F (31.1°C) range. The precipitation is to the tune of 4.3" (109mm) with 17 damp days in the month.
Afternoons can be hot, but temperatures rarely rise to extreme levels, and the humidity is tenable. Light summer clothing is the order of the day, and nights do not need extra layers. The water is the best remedy for the increasing heat and air-conditioners are in action indoors full time. Punta Dos Amantes is the most famous attraction of Guam with a spending view of the mountains, limestone plateaus, and reefs in the clear skies of May.
Expect moderate rainfall even on sunny days. However, it is still possible to be outdoors for long hours without rain protection gear. May receive an average of 220 hours of sunshine, the highest monthly amount of the year in Guam.
