Weather and Climate of Guam Island
Guam’s climate is tropical, with year round warm weather. Temperatures range from 21 to 32?C, with high humidity. Two clearly defined seasons exist: a dry season and a rainy season. The period from January to May constitutes the dry season in Tumon (the center of tourist activity) and the peak tourist season. Although this time is called the ‘dry’ season, the humidity is still quite high, and light cotton clothing is recommended.
The rainy season runs from July to November; and the months of June and December are variable – some years dry and sometimes rainy. Both seasons are affected by the easterly trade winds, which sometimes evolve into dangerous tropical storms.
Typhoons also can occur, so it is advised that you keep aware of weather forecasts. Source
