Guam is the largest island of the Mariana archipelago in the western Pacific and is home to about 190,000 inhabitants on an area of about 340 square miles.

As this is a so-called non-incorporated US foreign territory, Head of State Guams is the current US President Barack Obama. Guam has internal autonomy, so that although the inhabitants are Americans, they are not allowed to vote in the US elections, for example.

The island is located on a flat lime plateau about 1300 miles east of the Philippines and about 1500 miles south of the Japanese island Honsh?. This situation has always given Guam a high military significance for the USA.

But Guam is also a very popular tourist destination and the second most visited destination in the Pacific after Hawaii. The highest elevation is Mount Lamlam, 406 meters high.

The official language of the office is English, paid in US dollars. Many inhabitants speak Chamorro, the language of the original wine inhabitants, and Filipino language variants are also very common.

Climate in Guam

Due to its proximity to the equator, Guam has high temperatures all year round and a typically tropical South Sea climate. The island is one of the wettest regions in the world, but its breathtaking beauty is impressive. Basically two travel times can be distinguished on Guam:

The dry season runs from about mid-December to the end of June, has a lower humidity and somewhat more moderate day temperatures. December is still quite humid as a transition month, especially in the first half of the month.

At the beginning of July at the latest, the rainy season starts on Guam, trade winds now carry moist Pacific air to the island and heavy rainfalls and often thunderstorms occur almost every afternoon and evening. The risk of typhoons is quite low, but statistically Guam is affected about every 8 years during the rainy season.

When is the best time to travel in Guam?

The two different seasons already give an idea of the best time to travel on Guam, it is of course recommended to prefer the much more pleasant dry season on the island. Around Christmas it is already getting very friendly, but also traditionally very crowded and expensive in Guam.

We therefore recommend the period from mid-January to the end of May as the best travel time for the island paradise in Micronesia (South Seas). The dry season offers the best conditions for diving, snorkelling, swimming and all kinds of water sports. February is ideal for active holidaymakers, as it is not yet getting so hot.

Highlights and Sights

Even if the American culture has become very formative for Guam today, impressive remnants of the Spanish occupation can still be found on the island. Especially the Latte Stone Park, Two Lovers Point and the Plaza de Espana are worth a visit.

The two old shelters Fort Santa Agueda and Fort Nuestra Senora de la Soledad are also popular attractions in Guam. But the main attractions of the island are of course its beautiful beaches and the impressive underwater world, which made Guam a popular honeymoon destination and dream destination for divers.

The best beaches in Guam are Ritidian Point, Tumon Beach and Gun Beach. The latter passes directly into the neighbouring Ypao Beach Park at the Hilton Hotel. Under water, both the colourful diversity of species and the impressive wrecks on the seabed inspire with fantastic diving conditions.
