Hagatna Weather in September

September weather in Hagåtña

September feels hot, sticky and very wet. Days reach 29°C, and nights barely cool down. Rain falls on 29 days, with thick cloud and little sunshine, so expect showers to interrupt outdoor plans.

You can still visit Plaza de España and the Dulce Nombre de Maria Cathedral-Basilica between showers. Keep city sightseeing flexible, and leave time to duck into a café. Beach time may work in a dry spell, but don't count on a full sunny day. Long hikes and tightly timed outdoor plans are poor bets.

Events and local days

US Labor Day falls in September, and Guam observes it too. It's a public holiday, so some offices and services may close, though the date changes each year. September isn't one of Hagåtña's main festival months; Guam's Liberation Day celebrations take place in July.

If you hate crowds, September may suit you better than the busier February-to-April period. It's a wetter, quieter time to visit, and accommodation rates may be lower than in those popular months. Exact prices and crowds vary, though, and rain can make a quiet trip feel less convenient.

Making the most of your visit

Travelling with kids? Keep a rainy-day stop in mind, such as the Guam Museum near the Skinner Plaza area. It gives you a break from the heat and showers without leaving central Hagåtña.

For a local meal, try kelaguen, a Chamorro dish often made with chopped meat, lemon, onion and chilli. If you're heading to Latte Stone Park, go when the rain eases; the stones are outdoors, and muddy paths can make a quick visit less pleasant. Check local opening details for indoor sights around Labor Day.
