Guam Overview: Weather & Attractions

Guam lies in the western Pacific, where steady trade winds keep average sea‑level temperatures near 27 °C / 81 °F year‑round. A short, pleasantly dry season (roughly December – May) alternates with a wetter, more humid monsoon stretch (June – November) that can bring brief but intense downpours and occasional typhoons. Against this lush tropical backdrop you’ll find soft‑sand beaches such as Tumon Bay, dramatic limestone cliffs at Two Lovers Point, colourful reefs in the Piti and Tumon marine preserves for snorkeling and diving, hiking trails that tunnel through jungle to World War II sites and waterfalls, and cultural stops like Chamorro Village night market and the Guam Museum in Hagåtña that spotlight Chamorro dance, food, and history.

Best Times to Fly to Guam

Most visitors target the dry months—late December through early June—when skies are clearer, humidity is lower, seas are calm, and daily highs hover in the low to mid‑80s °F (about 29 °C). April and May often hit a sweet spot of reliable sunshine with slightly lighter crowds before summer holidays begin, so airfares and hotel rates can be more forgiving. Budget travellers who don’t mind afternoon showers or a higher typhoon probability sometimes choose September or October, when visitor numbers and prices dip, but they trade off with heavier humidity and cloud cover.

Guam Airport Information

The territory’s single commercial gateway is Antonio B. Won Pat International Airport (GUM) in Tamuning/Barrigada, about 5 km east of the capital. It has two long runways capable of handling wide‑body jets and serves as a hub for United Airlines’ Micronesia network as well as cargo carrier Asia Pacific Airlines. Recent authority statistics show passenger throughput rebounding to nearly four million travellers in fiscal‑year 2024 as tourism continues its post‑pandemic recovery. Ground transport options include taxis, hotel shuttles, app‑based rides, and rental cars; central Tumon hotels are a 10‑ to 15‑minute drive.

Major Departure Cities to Guam

Direct international links concentrate in Northeast Asia and the western Pacific. Tokyo (Narita and Haneda) and Seoul (Incheon) provide the highest seat counts, followed by Manila, Osaka, Nagoya, Fukuoka, and Hong Kong. Regional routes include daily hops from Saipan and regular service from Koror (Palau) and Rota. Guam’s longest nonstop from the United States is Honolulu (about seven hours), while itineraries from Australia, New Zealand, or the mainland U.S. typically connect through these Asian hubs.
