💰 Budget
Guam is priced like the US, with sales-style taxes on some services and tipping expected in restaurants. The Tumon hotel strip is the expensive option; guesthouses, the Chamorro Village market, and roadside barbecue and Filipino eateries keep costs down. A rental car is close to essential.
- Daily Budget Midrange
- USD 180–350 (Tumon hotel, restaurants, rental car and fuel, a boat or dive trip)
- Daily Budget Shoestring
- USD 70–120 (guesthouse, market and barbecue-plate food, shared rental car)
Eat at the Wednesday Chamorro Village night market in Hagåtña and the local BBQ and Filipino spots, and rent a car to reach the southern villages and the north.
✈️ Visa Requirements
Guam is US territory, so US entry rules apply, with one addition: Guam (and the Northern Marianas) operate a Guam-CNMI Visa Waiver Program that admits several extra nationalities, mainly for tourism. Visa Waiver Program travellers still need ESTA; others need a US visa. Arrivals from the US mainland or Hawaii are domestic.
- Typical Stay
- As for the US (ESTA/visa), plus the Guam-CNMI Visa Waiver Program for some additional countries (up to 45 days)
Check whether your nationality qualifies under the US Visa Waiver Program (with ESTA) or the separate Guam-CNMI program; otherwise get a US visa.
🛡️ Safety
Guam is generally safe, with petty theft, car break-ins at trailheads and beaches, and some alcohol-related trouble in the nightlife area the main concerns. Ocean hazards are significant — strong currents and surf outside the reef, and drownings occur. North Korea has periodically named Guam in missile threats, but this does not affect daily life or travel.
- Health
- Tap water is treated and generally safe; dengue can occur; the sun and the reef currents are the main hazards; there is a full hospital
Swim inside the reef and heed current warnings, don't leave valuables in cars at beaches and trailheads, and take normal night-time precautions in the Tumon bar district.
🌦️ Climate
Tropical, hot and humid year-round, around 28–32°C. The dry season runs roughly December to June and the wet season July to November, which is also the peak of the western Pacific typhoon season — Typhoon Mawar struck Guam directly in May 2023.
- Dry Season
- December–June
- Wet Season
- July–November (typhoon season)
🚆 Transportation
A. B. Won Pat International Airport at Tamuning has flights from Japan, South Korea, the Philippines, Micronesia, Hawaii, and the US mainland. A rental car is the standard way around the island; there is a limited public bus service and hotel shuttles along the Tumon strip.
Rent a car to see anything beyond Tumon; drive on the right, and note that large areas in the north and around Apra Harbor are military land and off-limits.
📅 Best Time to Visit
December to June, the drier season, has the most reliable weather and the calmest sea for diving and boat trips. July to November is wetter and carries the typhoon risk. Temperatures barely change through the year.
- Events
- Liberation Day (21 July), marking the end of the Japanese occupation, with a parade and carnival; the Guam Micronesia Island Fair; village fiestas for patron saints throughout the year; the CHamoru month of March (Mes CHamoru)
💱 Currency
The currency is the US dollar. Cards are accepted almost everywhere; carry small bills for the village markets, buses, and tips.

💬 Language
English is the language of government, business, and schooling and is spoken by nearly everyone. CHamoru, the indigenous Austronesian language, is co-official and the focus of revitalisation efforts. Filipino languages, chiefly Tagalog and Ilocano, are widely spoken given the large Filipino community.
