1. Location and geography

Guam only covers about 549 square kilometers (212 square miles) of land. To give you a better idea of its size, Rhode Island is almost five times bigger than Guam, and RI is the smallest US state by landmass.

Where is Guam located, you ask? This island is situated in the Western North Pacific Ocean, over 2,500 kilometers (1,550 miles) east of Manila and some 6,350 kilometers (3,945 miles) from Hawaii, which is almost an 8-hour flight. Location-wise, Japan and the Philippines are closest to Guam, and both are only four hours away by plane.

2. History

Small as the island might be, it has a rich and fascinating history that dates back to 2000 BC. Before it became an unincorporated US territory, Guam was inhabited by Austronesians - now called the Chamorro people - who migrated from Southeast Asia.

Portuguese explorer Ferdinand Magellan came to the island in 1521 to stop for provisions, and although history records this visit as Guam’s first contact with Europe, the island wasn’t officially colonized by Spain until 1668, with the arrival of the Spanish Jesuits. In 1898, during the Spanish-American War, the United States took over Guam. Years later, during World War II, Japan briefly occupied the island, but they were defeated by the Americans in 1944.

3. Language and culture

The people of Guam speak Chamorro and English, but some of the older generation - those who were alive during World War II and the Japanese occupation - also speak Japanese. Chamorro language, similar to other languages spoken in Southeast Asia, is an Austronesian language that has been influenced by Spanish, English, and even Japanese.

Phrases such as “good morning” in Spanish and Chamorro are nearly the same, with Chamorro being “buenas dias”. Other phrases you might hear on the island that sound Spanish include “pot fabot” (please), “ki ora?” (what time is it), and “kuånto este?” (how much is this?).

4. The Chamorro people

The Chamorro people in the Mariana Islands, including Guam, can trace their ancestry back thousands of years - they came from Southeast Asia and were known to be seafarers. Early Chamorro society was divided into castes: there was a lower caste and a higher caste. The latter, however, was also divided into an upper-middle class and a ruling class.

Besides having a caste system, the Chamorro people were matriarchal, with women serving as clan and spiritual leaders. Today, most Chamorro families still continue their matrilineal practices, with the mother being the head of the household.

Weather in Guam

11. General climate and seasons

As a tropical island, Guam enjoys warm weather year-round. Much like other tropical destinations, there are only two seasons: dry from January to May, and rainy from July to November. The average temperature is typically around 80 degrees Fahrenheit (26 degrees Celsius), and while it’s quite humid for most of the year, it tends to cool down from November to March.

Storms and typhoons

Due to its location in the Pacific Ocean, Guam is no stranger to typhoons and tropical depressions. The island usually experiences three typhoons per year, but their typhoon season is known to last year-round, with most of them developing sometime between May and November.

Locals are well-prepared for such weather, and they stay tuned to forecasts on the radio or use social media to track any oncoming typhoons. Communities are also familiar with the term “COR” or Conditions of Readiness, which tells them what to look out for. As a safety precaution, Guam is always on COR 4, which stands for “always ready”.

12. The best time and season to visit Guam

Mid-January is the best month for a Guam travel, as the weather is still warm but not as humid, and you’re more likely to avoid the rain. Keep in mind, however, that peak tourist season in Guam is often around February, with January and June following close behind. Beaches will be a bit more crowded and hotel rates will likely be more expensive. However, the pleasant weather and opportunities to snorkel, swim, and lounge on the beach can’t be beaten!

18. Guam's cuisine

When it came to food, the early Chamorro people relied on their fishing skills and also harvested from the island. Their diet consisted of food made with ingredients such as coconuts, yams, bananas, fowl, fresh fish, and rice. Today, Guam’s cuisine is a mix of early Chamorro cooking practices and influences from other countries, including the Pacific Islands. Some of their best dishes include rice and coconut, so you can expect a delicious and filling meal every time!

19. Best dishes in Guam

Being an unincorporated US territory, you’ll definitely find familiar fast-food chains in Guam. But you’ll want to skip these places in favor of restaurants serving delicious local cuisine.


Kelaguen is a traditional Chamorro dish that might remind you of ceviche, as it’s a raw protein - such as shrimp or fish - marinated in lemon juice, green onions, pepper, and coconut. Chicken kelaguen is also popular, but the chicken version is usually grilled beforehand. This dish is best eaten over rice or with a soft tortilla.

Red rice

Rice is a staple in Guam, and you can’t leave the island without enjoying a meal served with red rice. The rice is cooked with achiote seeds or paste, which gives it the bright orange color and flavor.


Many tourists have come home from a trip to Guam singing praises about the local food - especially the barbeque. They marinate their meat a day before it hits the grill, so the meat has hours to soak in all the flavors from the soy sauce, vinegar, and garlic. Chicken and spare ribs are popular, and it’s grilled using a local wood called tangan-tangan. Eat this with red rice and some finadene sauce (a local soy sauce mix) and you have the perfect meal!


If you’ve got a sweet tooth, wrap up your meal with dessert and order some latiya. This is a cinnamon custard with a cake base, either sponge or yellow cake - but some recipes use angel cake or pound cake, too. A thick custard made with butter, evaporated milk, and cornstarch is poured over the cake base and topped with cinnamon.
