Guam

Climate & when to go

Guam has a uniform climate: warm and humid throughout the year. Daily temperatures average a low of 22°C and a high of 30°C. The dry season (January to late April) provides the most pleasant weather, with slightly lower humidity and a monthly rainfall average of just 114mm.

Ominously, Guam is in a sector of the Pacific Ocean known as 'Typhoon Alley'; typhoons are said to hit the island once every eight years, usually during October and November. The most recent occurrence was in 2002, when Supertyphoon Pongsona stalled over Guam for a full day, with wind speeds of 180km/h that levelled over 1000 homes and killed four people.
