July weather forecast
Guam, USA

July in Guam is characterized by the heart of the wet season, presenting a fusion of warmth and consistent rainfall. Temperatures during this month are typically situated between 81°F (27.2°C) and 90°F (32.2°C), representing some of the year's hottest conditions. The consistent warmth combined with significant rainfall marks July as one of the most humid months on the Guam calendar.

The entire expanse of Guam experiences these tropical conditions. The island, already immersed in the wet season initiated by June, now sees its landscapes drenched in frequent showers, intensifying its lush green aura. The marked departure from the drier conditions of earlier months is palpable, as July epitomizes Guam's tropical rainforest climate.

Rain showers become even more frequent in July compared to June, with precipitation levels peaking for the year. However, the steadfast northeast trade winds, ranging from 10mph (16.1km/h) to 20mph (32.2km/h), continue to moderate the island's climate, offering periodic relief from the consistent humidity and rain.

The warm oceanic waters around Guam remain inviting, but the higher chances of rain and potential storms necessitate extra caution for those engaging in marine activities. As July ends and August beckons, the island readies itself for even more rain, with August historically being among the wettest periods in Guam.
