April weather forecast
Guam, USA

April in Guam marks a definitive shift towards the warmer spectrum of the year. The temperatures during this month vary between 78°F (25.6°C) and 87°F (30.6°C). Notably, the higher end of this range approaches the all-time record for the island, which was 96°F (35.6°C) set on April 18, 1971. This makes April one of the warmer months in the Guam calendar.

Despite the island's small size ensuring uniform climatic conditions across its regions, the warming trend is felt island-wide. As a direct contrast to the milder temperatures of March, April brings a tangible increase in warmth, hinting at the impending peak of summer.

The month of April still benefits from the tail end of the dry season, ensuring rainfall remains relatively low, though it starts to increase compared to the preceding months. The ever-present northeast trade winds, flowing between 10mph (16.1km/h) and 20mph (32.2km/h), play a crucial role in moderating potential heat spikes, providing relief, especially during midday.

The ocean temperatures rise in parallel with the land, making it conducive for extended marine activities. With May on the horizon, the anticipation of the wet season's onset becomes evident, as April acts as a bridge between the relatively cooler dry season and the hot, humid months to follow.
