Rules in force · 9Bags go from the car to the hotel door
  • Oceania ↗Oceania's island states guard their farms and reefs at the border: tick 'yes' on the arrival card for any food, plant, animal product, soil or used outdoor gear, and let the officer decide.
  • Oceania ↗Across the tropical South Pacific, cyclones are possible from November to April: choose insurance that covers weather delays and keep one spare night before a long-haul departure.
  • Micronesia ↗Micronesia runs on a handful of weekly flights, so one cancellation can cost several days: build slack into every connection between islands.
  • Guam ↗US entry rules apply: visitors need a US visa, ESTA under the US Visa Waiver Program, or eligibility for the Guam–CNMI Visa Waiver Program. Check US Customs and Border Protection for your passport; the Guam–CNMI waiver does not allow onward travel to the rest of the US.
  • Guam ↗Guam is outside the US customs territory: complete the Guam customs declaration on arrival and declare food, plants and animal products.
  • Guam ↗Drive on the right, as in the mainland US; a valid foreign licence is accepted for short visits.
  • Tumon and Hagåtña ↗Buses are infrequent and a hire car or a tour is the practical way to the south; book it for the dry months if you can.
  • Tumon ↗Bags go from the car to the hotel door; the strip is flat but hot and the crossings are far apart.
  • Tumon ↗Plan the south and Hagåtña as one hire-car day: the strip has taxis but the sights beyond it do not.

Know before you go

  • The whole bay is a marine preserve: fishing and taking coral or shells are banned.
  • Guam law keeps beaches public; you can walk to the sand between hotels, but hotel chairs and umbrellas are for guests.
  • Water is warm all year; the calm months are roughly Feb–May.
  • Waves and rip currents rise in the wet season (Jul–Nov) and after storms: swim only with the flag down.
  • UV is strong from about 09:30; use reef-safe sunscreen and a rash vest.
  • There are showers at some public access points and at hotels; carry a towel from your room.

Best time of day

Go before 10:00. Plan 60–90 min inside.

  • Closing buffer is measured against a planning close of 18:30. The beach is open all hours; plan to be out of the water before dusk.

How to do it well

  1. 1Walk down from your hotel to the sand before 09:00 and swim inside the reef.
  2. 2Rent or bring a mask and snorkel; swim parallel to the shore, not out to the reef edge.
  3. 3Take a shaded break from 11:00 to 15:00 and come back for the sunset walk.
  4. 4If the sea is rough (wet season, swell days), swap to the pool or the aquarium and try again the next morning.

Questions and answers

answered by Voykit editors · dated
Is the water calm all year?

No: it is calmest Feb–May; Jul–Nov swell and storms make it rough.

Checked 2026-09-29 · Voykit desk

Are the beach chairs free?

Only for hotel guests; check fees for non-guests.

Checked 2026-09-29 · Voykit desk

When is the best time to swim in Tumon Bay?

07:00–10:00 on a calm day, before the sun and the wind pick up. Wet-season swell (Jul–Nov) can make it rough.

Is Tumon Bay good for snorkelling?

It is a shallow reef inside a marine preserve. The north end near Gun Beach and the south end near Ypao have the best reef close to the sand; look, do not touch.

Do I have to pay for the beach?

No. Guam beaches are public. You pay only for gear, chairs or tours.

Are there lifeguards?

Cover is patchy. Some hotels post lifeguards at their stretch; otherwise swim with a buddy and heed the flags.

Is the beach safe at night?

The promenade is lit and busy near the hotels, but do not swim after dark and keep valuables in the room.

What should I wear in the water?

Reef shoes, a rash vest and reef-safe sunscreen; check current Guam rules on sunscreen ingredients.
