When Is the Best Time To Visit Guam?
The answer to the question of what is the best month to visit Guam depends on what you are interested in doing during your stay. Here you can see an overview of each month and its typical weather conditions.
Climate of Guam
Guma is located in a humid equatorial climate zone tempered by the northeastern stripes. The weather is characterized by high temperatures ranging from 25°C - 32°C and humidity levels of up to 70%. Water temperature also remains consistently high at around 28°C. Precipitation varies and oscillates between 2000 mm - 3000 mm per year.
On the island we can distinguish between the dry and rainy seasons.
The rainy season covers the time from July to December. The frequency and intensity of rainfall and thunderstorms increases, and it is also hotter and more humid, although at the same time there is no shortage of sunny and bright days.
The dry season lasts from January to June, bringing the most favorable weather. Slightly cooler and sunny days attract tourists, and the precipitation that occurs in no way impedes leisure activities.
