Guam : climate and when to go to Agana

The climate of Guam is a pleasantly warm tropical climate all year round. The average annual and constant temperature is 82F as the temperature of the bathing water.

The coolest and least humid months (everything is relative), marked by the trade winds of the west, go from December to February. Although the warmest months go from March to August, refreshing trade winds blow regularly.

There are two seasons, the dry season, called "fanumnangan", begins in December and ends in June. The rainy season, called "fanuchanan", begins in July and ends in November.

Typhoons can strike Guam from July to mid-November and can sometimes cause heavy damage and flooding. However, this is rare because the typhoon roads are usually very far to the west to reach Guam.

We recommend light cotton clothing throughout the year, with an umbrella or a raincoat for sudden heavy showers. No matter where you go, be prepared for high temperatures and humidity.

When to go? The hottest month for the beach, lazing around and swimming is August. Check the precipitations because heavy showers may occur, otherwise other periods are possible. The coolest month is February, if you can not stand the heat too much. The driest month of the year is March, if you do not like the rain at all.

Weather uncertainties 2021 to go to Agana ?

Stormy risks under tropics

Risks of tropical rains and showers
In the tropics, these storm or rain pictograms indicate that tropical showers or stormy weather are possible. It is difficult to predict the exact local weather in the tropics. This is especially true by the sea and the beach. Consider that more than 180 mm of rain per month is the limit to enjoy the beach on vacation. So check this data provided for each month on the preferred destinations of this site.

When traveling in the tropics as a seaside, rain is not welcome. If you see this indicator, with possible storms, that does not mean that it will rain all day long. When we observe the local rainfall, it is either really zero or very weak. Meteorologists prefer to be pessimistic. So observe below, the skies photographed during a week announced stormy in Asia. It did not rain once. I invite you to integrate this parameter before going to Agana for a good trip to the sun!
