December marks the return of Guam's dry season — clear blue skies, minimal rain, and excellent beach conditions. Christmas and New Year celebrations bring a festive atmosphere across Tumon hotels. Crowds and prices rise through the month as Japanese and Korean tourists arrive for the holidays.

travel tips
Book hotels and restaurants for Christmas and New Year's Eve at least 3 months in advance — December 24–31 fills up faster than almost any period.
Christmas Day (December 25) is a public holiday — many smaller restaurants and shops will be closed. Stick to hotel dining if you haven't planned ahead.
Misa de Gallo (novena of midnight masses before Christmas) begins December 16 — a beautiful cultural tradition to witness at local Catholic churches.
common questions
Yes — December is one of the best months to visit Guam. The dry season has returned, weather is excellent, and the Christmas atmosphere in Tumon is festive and vibrant. The trade-off is peak season prices and holiday crowds, especially in the last week of December.
CHamoru Christmas centers on family gatherings, traditional food (CHamoru tamales, red rice, roast suckling pig), and the Misa de Gallo — a series of midnight masses held from December 16 to Christmas Eve. Village churches are beautifully decorated and the community atmosphere is warm and welcoming.
Pack light summer clothing — December is dry season and excellent beach weather. Evenings can feel slightly cooler (24–25°C), so a light layer is useful for outdoor dinners. A nicer outfit is worth packing for Christmas and New Year's Eve dinners, which are often formal at resort hotels. Sunscreen is essential. Book beach equipment (sun loungers, snorkel gear) in advance during the Christmas week as availability tightens.
Book as early as possible — ideally 3–6 months in advance for December 24–31. This period is one of the most in-demand in the entire year. Hotels sell out first, then restaurants for Christmas Day and New Year's Eve dinners, then sunset cruise and activity slots. If you're planning to visit during the holiday week, early booking is essential. The first three weeks of December are easier to book and still have excellent weather.
