Visiting Hagatna in December

December weather in Hagåtña

December feels warm and sticky, with little change between daytime and night. Rain falls on many days, but showers don't usually rule out a whole day outdoors. You can explore Plaza de España, visit the Dulce Nombre de Maria Cathedral-Basilica, or take a coastal walk when skies clear.

The sea and beaches are still inviting, but don't count on every afternoon being sunny. If you're planning a long hike or a full day at the beach, keep a flexible option for rain. December is drier than November, though January gets more rain.

Christmas and New Year

Christmas is an important holiday in Guam, where many people are Catholic. You'll see festive decorations, and churches hold Christmas services. New Year brings another reason for families to gather, though specific public events can vary from year to year.

Travelling with kids? A visit to the cathedral and a stroll around central Hagåtña make an easy outing between showers.

Crowds and local tips

Holiday travel can make the period around Christmas and New Year busier than a quieter month. Flights and hotels may cost more then, while February to April are the best months overall for weather. December's conditions are still good for a city break, but it isn't the clearest time of year.

For a practical rainy-day stop, head to the Guam Museum near Plaza de España. You can spend time indoors, then see the nearby historic sites if the weather lifts. If you hate crowds, visit Hagåtña's central sights outside the main holiday days.
