Visiting Hagatna in January

January weather in Hagåtña

January feels warm and very humid, with daytime highs around 28°C and nights barely cooler. Rain falls on many days, often as showers, and cloudy skies can interrupt the sunshine. The month gets more rain than December, though February is usually drier.

You can still explore Plaza de España, the Guam Museum and the cathedral between showers. Short walks around central Hagåtña work better than committing to a long, exposed hike. For beach time, keep your plans flexible; rough, rainy spells can spoil a full day by the water.

What's on

New Year's Day is a public holiday, so some shops and services may close or keep shorter hours. January isn't known for a major annual festival in Hagåtña. For a lively local evening, the Chamorro Village Wednesday Night Market brings food stalls and crafts together. Rain can make the outdoor market less comfortable, so check the forecast before you go.

Travelling with kids? The Guam Museum offers an indoor break when showers roll through.

Crowds and local tips

January can be busy across Guam, with winter visitors adding demand after the year-end holidays. Hagåtña is quieter than the main resort areas, but popular sights and restaurants may still feel busier than in the calmer summer months. Prices can be higher during the holiday period; after New Year, they may ease, though exact deals vary.

At Chamorro Village, try kelaguen, a tangy Chamorro dish often made with chicken or seafood. Carry a small umbrella for the walk between stalls, and use the market's covered areas when showers pass. If sunshine matters most, February to April generally brings better weather than January.
