The Overall Best Time to Visit Guam

The best time to visit Guam is in the late winter/spring, from January through May, since the weather is temperate and rainfall is lighter.

During this season, you can snorkel, dive, hike, climb, visit, explore, and shop without worrying about the heavy rains or intolerable summer heat.

From January through May, average temperatures range between 74 and 89 degrees Fahrenheit, allowing you to enjoy outdoor activities without worrying about the heat.

This is also the dry season in Guam, with average rainfall ranging between 3.9 and 4.2 inches of precipitation a month. The water temperature is also warm — it averages 86 degrees Fahrenheit but isn’t so warm that a jump in the ocean doesn’t feel refreshing.

There are also many festivals and activities during this season. Guam Discovery Day is the first day of March and marks the finding of Guam in 1521 by Spanish colonizers.

The Malojloj Festival, one of the most anticipated days of the year, is held in May and consists of a three-day-long festival commemorating the patron saint San Isidro. There are often many parties along the street and in front of the local church.

In the winter, you can enjoy arid conditions, which improve visibility for underwater sports like diving or snorkeling. Additionally, you can hike through the ancient protected limestone forests, which are lovely and rare worldwide.

Prices may climb in winter as crowds thicken in January and February. However, prices will typically be lower later in the season as the year progresses. If you’re looking to maximize your finances, you can choose to go in April or May.

The cheapest time to visit Guam is in November since this month is the peak of the winter season before the holidays.

Flights are cheapest in November, and food, accommodations, and transportation prices are lower than average since fewer people are there.

Additionally, fewer people are traveling in November, as it is the end of the rainy season and does not correspond with Western holidays. November is typically warm and rainy since it is the end of the rainy season in Guam.

You can typically plan for activities, but you may need to reschedule if there is heavy rainfall. Temperatures range from 77 to 88 degrees Fahrenheit, and rainfall is relatively high at 8.08 inches per month.

Because heavy rains can make for turbulent oceans and rivers, you may not be able to engage in underwater sports like scuba diving or snorkeling.

Remember to plan and remain flexible and open to accommodation if necessary. November is an excellent time to visit Guam. Because it is an unincorporated U.S. territory, the people of Guam celebrate some of the same holidays.

You can go to Guam for Thanksgiving and enjoy the local celebrations or visit All Souls Day on November 2nd and enjoy religious processions and cultural and culinary experiences.

The churches in Guam are beautiful and open to visitors so that you can visit during and outside of religious holidays.

The least busy time to visit Guam is in September and November, since this period represents the peak of the rainy season, and temperatures reach 90 degrees.

Additionally, most people work during these months, as they do not correspond with significant holidays or summer seasons, so there are likely to be fewer people traveling.

Since there are fewer international travelers, prices are relatively low later in the season, towards November and early December. The winter months will likely afford you the most bang for your buck if you are on a budget.

In September-November, the temperature in Guam ranges from 88 degrees to 76 degrees Fahrenheit. Rainfall is exceptionally high at an average of roughly 8-13  inches per month.

High rainfall can mean limited ocean visibility should you choose to go scuba diving or snorkeling, and rain could impede your plans to go hiking or climbing.

However, Guam has many things to do during the autumn season. First, you can explore one of the island’s many beautiful cave systems, including Gadao’s Cave and Pagat Cave.

Guam is known for its beautiful caves full of wildlife and ancient drawings — an excellent activity for any history buff. There is also a local festival called Pastries in Paradise that features desserts and confections crafted by the best chefs in Guam and beyond.

The Guam Hotel hosts the event, and the Restaurant Association hosts the event and is sure to offer an incredible experience for anyone attending.

The worst time to visit Guam is in June or July, as the temperature rises to 90 degrees and rainfall is relatively high for the area at 7-12 inches per month.

Additionally, these months correspond with the Western/Northern summer months, during which millions of families travel worldwide. As a result, Guam, which is a relatively small island, can get quite crowded during these months.

If you choose to visit Guam during June or July, there is still plenty you can enjoy! Conditions are often favorable for most activities, and you can enjoy relatively low prices at shopping malls and storefronts.

Guam Liberation Day is the second week of July, with many more festivals, concerts, and events. Many people prefer to visit Guam in the summer as they can enjoy the island’s rushing waterfalls and gorgeous thunderstorms, both of which contribute to the island’s romance.

Remember that accommodation can get booked quickly due to the summer crowds, so you’ll need to make reservations ahead of time.
