Why Visit Guam?

Guam, a United States territory in the Western Pacific, is an island paradise renowned for its stunning landscapes and unique culture.

Hagåtña, also known as Agana, serves as the capital, while Tumon Bay is a popular tourist area. Guam’s culture is a rich fusion of indigenous Chamorro traditions and American influences, evident in its language, cuisine, and celebrations. The island’s strategic location and strong U.S. military presence make it a key hub in the Pacific.

When Is the Best Time to Visit Guam?

The best time to visit Guam is during the dry season, which runs from December to May. During these months, the weather is generally sunny and warm, with little rainfall. This makes it ideal for enjoying the island’s many outdoor activities, such as swimming, sunbathing, snorkeling, and diving.

Benefits of visiting Guam during the dry season:

  • Sunny weather: Guam has a tropical climate, with warm temperatures and humidity year-round. However, the dry season offers the best chance of sunny weather, with less rainfall and more sunshine. This makes it ideal for enjoying the island’s many outdoor attractions.
  • Clear waters: The dry season is also the best time to visit Guam for its clear waters. This is because there is less rainfall and runoff during this time of year, which means that the water is more visible and there is less chance of algae blooms.
  • Fewer crowds: Guam is a popular tourist destination, but the dry season is less crowded than the peak summer season. This means you’ll be able to enjoy the island’s attractions without having to deal with large crowds.
  • Lower prices: Prices for flights, accommodation, and activities are generally lower during the dry season than during the peak summer season. This means you can save money on your trip without having to sacrifice quality.

Specific examples of how you can enjoy the most of Guam during the dry season:

  • December to January: The weather in December and January is typically sunny and warm, with occasional showers. This is a great time to visit Tumon Bay, Ritidian Point, and Asan Beach. You can go swimming, sunbathing, snorkeling, and diving.
  • February to May: The weather in February to May is also typically sunny and warm, with occasional showers. This is a great time to visit Two Lovers Point, Talofofo Falls, and the War in the Pacific National Historical Park. You can go hiking, biking, and explore historic sites.

While it is possible to visit Guam at any time of year, the dry season of December to May offers the best combination of sunny weather, clear waters, fewer crowds, and lower prices.
