💰 Budget
Tumon is the most expensive place to stay on Guam, and prices follow US levels with hotel taxes on top. Rooms rise steeply around Japanese and Korean holiday weeks, Liberation Day and Christmas. Costs drop quickly for anyone eating at the plate-lunch and Filipino places behind the strip rather than in the hotels, and the beach, the reef and the bay cost nothing.
- Daily Budget Midrange
- USD 180–350 (Tumon hotel, restaurants, hire car and fuel, a boat or dive trip)
- Daily Budget Shoestring
- USD 80–130 (guesthouse or budget hotel behind the strip, plate lunches and food courts, the public bus or a shared shuttle)
A hire car pays for itself within a day or two for anyone leaving the strip; snorkelling gear is worth bringing or buying cheaply, as the best swimming is straight off the beach.
📅 Best Time to Visit
January to May, the dry season, has the most settled weather, the clearest water and the calmest sea for boat trips. July to November is wetter and more humid, and is also the typhoon season. Temperatures barely change, so the choice is really about rain, crowds and room rates.
⏳ Suggested Number of Days
Two or three days cover the bay, the reef and the capital nearby. Four or five suit anyone adding the southern villages, the northern beaches and a diving or fishing trip. Without a hire car, allow an extra day for slow bus and shuttle connections.

🚆 Transportation
Hotel and shopping shuttles and a trolley-style bus run up and down San Vitores Road, which is the only route most visitors need. Taxis wait at the hotels, and ride-hailing is limited, so a hire car is the usual way to reach the rest of the island. The island bus system is cheap but infrequent. Traffic drives on the right.
Large areas in the north of the island and around Apra Harbor are military land and closed to the public, which shapes any driving route.
🛬 Airport & Station Connections
A. B. Won Pat International Airport at Tamuning is about 3 miles south of the strip, roughly ten minutes by taxi or hotel shuttle. Flights arrive from Japan, South Korea, the Philippines, Honolulu, the US mainland and other Micronesian islands; arrivals from the United States are domestic. Nearly everyone reaches Tumon by air and is driven the short distance in.
🚶 Walkability
Unusually for Guam, Tumon works on foot. The strip runs about two miles with pavements most of the way, and the hotels, shops, restaurants and beach entrances sit along it, so a stay here needs no vehicle. Heat, humidity and heavy midday sun make shade and water matter more than distance. Anything beyond the bay involves a road built for cars.
🛡️ Safety
Tumon is generally safe, and the strip is busy and patrolled. The usual problems are petty theft, break-ins to parked cars at beaches and trailheads, and alcohol-related trouble in the bar area late at night. The sea deserves more respect than the streets: currents run strongly through the reef channels and drownings happen, mostly outside the reef line.
Swim inside the reef, watch for channel currents near Gun Beach and the bay mouth, leave nothing visible in a parked car, and keep to busy streets after dark. Check current official travel advice before travelling.
🌦️ Climate
Tropical, hot and humid all year, with highs usually in the mid-80s °F and nights in the mid-70s °F. The dry season runs from January to May and the wet season from July to November, when short heavy showers are common and typhoons are a real risk; and Typhoon Mawar passed close to the island in May 2023.
- Summer
- hot, humid and wet — highs near 87°F, frequent afternoon downpours and the start of the typhoon season
- Winter
- the dry season — highs near 85°F, lower humidity, steady trade winds and the calmest sea
🤝 Local Customs
Guam is US territory with CHamoru manners. Tipping is expected in restaurants, at about 15 to 20 per cent, and for taxis and hotel staff. Family and church come first, so Sunday mornings are quiet and village fiestas are open-house occasions. Elders are greeted respectfully, and the traditional mangnginge' — taking an elder's hand to the face to sniff it — is still practised. Swimwear belongs on the beach, not in shops or churches.
Ask before photographing people, fiestas or funerals; do not photograph military installations; and remember that ancient latte stones and burial sites are treated as sacred, not as climbing frames. The drinking age is 21.
💳 Common Payment Methods
The currency is the US dollar. Cards and contactless payment work in hotels, restaurants and shops along the strip, and ATMs are easy to find in the hotels and shopping centres. Small amounts of cash are useful for buses, market stalls, roadside barbecue and tips. Japanese yen and Korean won are not generally accepted.
