Guam in January | New Year's Day, MLK Day, and the Tumon Fiesta

Guam Has Two Holidays in January: New Year's Day and MLK Day

Check Guam's government calendar for January and you'll find two holidays: New Year's Day on January 1, and Martin Luther King Jr. Day on the third Monday of the month. In 2026, that puts them on Thursday, January 1 and Monday, January 19. Few months carry two holidays, which makes January a busy month for Guam right out of the gate.

New Year's Day itself isn't a uniquely Guam holiday — it's shared with the rest of the United States. During the Spanish colonial era, the day was reportedly marked more by Mass and blessings for the year ahead than by big celebrations. After Guam became a U.S. territory in 1898, mainland customs like countdowns and fireworks blended in, shaping the holiday into something closer to what it looks like today. Fireworks now light up spots like Tumon Bay and Hagåtña from New Year's Eve into the early hours of January 1, with families gathering to see the year in together. Guam's population includes a large Filipino community alongside Chamorros, and that shows on the table too — round fruits and bunches of grapes hung by the doorway are said to reflect Filipino New Year customs that have taken root on the island.

The second holiday, Martin Luther King Jr. Day, honors the birthday of the civil rights leader. President Reagan signed it into federal law in 1983, and it was first observed in January 1986 — making 2026 the 40th anniversary of that first observance. Because the holiday falls on the third Monday of January rather than a fixed date, it shifts year to year; in 2026 it's January 19. Martin Luther King Jr. Day is specifically listed on the Government of Guam holiday calendar. Guam's observed-holiday calendar is not identical to the federal calendar, so travelers should use the GovGuam list rather than assume every U.S. federal holiday is observed locally. We couldn't confirm any large annual parade on the scale of those held in mainland cities, but local coverage suggests some schools hold lessons on King's legacy in a given year — a quiet occasion for reflection more than a day of big public events.

Tumon Fiesta, a Village Celebration in Central Guam

Throughout the year, Guam's villages hold fiestas honoring the patron saint of their parish church, and January is no exception. In Tumon — better known these days as the island's tourist hub — the village fiesta honoring Blessed Diego Luis de San Vitores traditionally falls around January 10, at the Blessed Diego de San Vitores Church on San Vitores Road.

Across Guam, a fiesta typically follows Mass with a village-wide feast — neighbors and relatives bring dishes to share, and even passing visitors are often welcomed to the table. It's the same spirit of a genuine, faith-rooted community celebration you'll find at the San Dionisio Fiesta in Humåtak in October. January is unusually packed with these: Barrigada (around January 4), Chalan Pago (around January 17), Mongmong (around January 24), and Maina (around January 31) all hold fiestas in quick succession, making it one of the busiest "fiesta months" on the calendar.

Why Tumon Carries the Memory of a 1672 Martyrdom

Tumon honors Father San Vitores because it's where his story ended. The Spanish Jesuit missionary Diego Luis de San Vitores arrived on Guam in June 1668 and named the archipelago the "Mariana Islands" after the Spanish queen regent. He built the first Catholic church in the islands, baptized many Chamorros starting with Chief Kepuha of Hagåtña, and founded schools for boys and girls — laying much of the religious and educational groundwork of the island.

On April 2, 1672, San Vitores and his Filipino assistant Pedro Calungsod were killed in Tumon. Accounts of the events leading to the killing come largely from missionary records and later religious tradition, so it is better not to present a single motive as uncontested fact. San Vitores was beatified in 1985; Calungsod was beatified in 2000 and canonized in 2012.

A shrine still marks the spot where San Vitores is believed to have died, near the Outrigger and Reef hotels on the north end of Tumon Bay, with a statue depicting the baptism scene. Separately from January's fiesta, an annual commemorative procession is held near the anniversary of his death each April (in 2026, it falls on April 4). Keep that history in mind next time you're walking through Tumon — beneath the resorts and storefronts is a site that's carried this memory for more than 350 years.

Exact fiesta dates and details can vary by year, so check the Guam Visitors Bureau's official site before you go.

January Weather and Driving Tips

January sits at the start of Guam's dry season, its driest stretch of the year. Average temperatures run roughly 26–29°C, humidity trends lower than other months, and monthly rainfall averages around 80mm — a fraction of October's 150–250mm. Clear skies are common, making it one of the more comfortable months to be outdoors.

Tropical cyclones can affect Guam in any month. NWS Guam’s long-term climatology found that 66% of tropical storms and typhoons passing within 180 nautical miles occurred from August through November, with October the most active month; January is comparatively quieter. Even in the dry season, check the latest forecast before driving, and allow extra time around busy Tumon areas when visitor traffic is heavy.

• Watch for pedestrians stepping into the road around Tumon and slow down more than usual
• Rental inventory and rates swing more during peak season, so lock in your booking early
• Around New Year's and the MLK Day long weekend, roads and attractions get busy — build extra time into your schedule
• Even on clear days, low afternoon sun can cut visibility, so keep sunglasses handy

Planning to Visit Guam in January? Compare Rental Car Rates Early

January through March offers some of the best weather of the year, but it's also peak tourist season, and popular vehicle classes book up fast. If your trip falls around New Year's or the MLK Day long weekend, it's worth comparing rates and vehicle options early and booking with some breathing room.
