Dive Travel / Guam
Guam is known as the gateway to Micronesia and provides a range of exciting activities that are complementary to its closest island neighbors. A trip to Guam can encompass many activities, including diving in the Marianas Trench, the deepest water in the world; snorkeling in amazingly diverse coral reef areas; jungle trekking to secluded beaches, historic sites and pristine waterfalls; sea kayaking the coast and swimming with the dolphins and experiencing the rich Chamorro culture and warm hospitality that is distinctly Guam. Guam also offers top-level golf courses designed by golfing greats such as Jack Nicklaus, Gary Player, and Sam Snead. The island also has a pleasing selection of Asian, European and Chamorro-influenced dining establishments, luxury resorts and moderately priced hotels.
There's little seasonal variation, so Guam's climate is always warm and humid. Nighttime lows hover around the mid-70s while average daytime highs approach the mid-80s. Guam's mild rainy season extends from September to December.
Due to its proximity to the equator, Guam's water temperatures remain in the low to mid-80s year-round.
The visibility varies at dive sites around Guam, but you can usually count on triple-digit vis on outer reefs, while Apra Harbor sites are usually in the 30- to 60-foot range. The calmest months are usually April through August.
Because it is a U.S. territory, there are no restrictions for U.S. citizens traveling to and from Guam. The traveler must, however, carry proof of U.S. citizenship. A certified birth certificate will suffice. Non-U.S. citizens must have valid passports issued by their respective governments and appropriate visas issued by a U.S. embassy or consulate.
