Weather in June

June is a transitional period in Guam from the dry to the wet season. The average temperatures hover in the 77°F (25°C) to 88°F (31.1°C) range, with 6.5 hours of daily sunshine.
June is fit for people looking for comfortable weather and affordable rates on flights and hotels. Additionally, the crowds dwindle with the onset of the wet season by the end of the month. The average rainfall increases to register a significant 7.1" (180mm) within 25 wet days in the month. Trade winds, which were strong earlier, lose strength resulting in increasing cloud cover.
Mornings and evenings are the best times of the day to avoid a downpour and enjoy the beaches. Sunrays are intense from 11 a.m. to 4 p.m., and it is advisable to avoid open beaches during this time. An umbrella or a rain jacket is useful in Guam as the precipitation occurs almost every day in June.
