About Guam
Guam is a tropical Pacific gem that offers year-round warm water and consistent wave opportunities across its diverse coastline. With ten quality spots spread across two distinct regions—South & East Guam featuring a mix of reef and beach breaks, and West & North Guam dominated by powerful reef formations—the island caters to surfers of all levels. The surrounding coral ecosystems create unique wave characteristics, though they demand respect and proper footwear.
The waves here are typically smaller than what you'd find on mainland breaks, with regional averages hovering between 0.7 and 1.2 meters. Don't let the modest numbers fool you though—Guam's reef breaks pack punch and offer quality over quantity. The best scoring days can reach into the 80s, particularly in January, March, April, and July, giving you plenty of standout sessions to chase. Water temperatures stay beautifully warm year-round, ranging from 28.3°C to 30°C, meaning you'll rarely need more than boardshorts and a rash guard.
Winter months (December through March) offer the most consistent swell and best scores, with January hitting an average score of 40 and February staying strong despite slightly lighter average conditions. Summer (June through September) sees the smallest waves and lightest winds, making it ideal for learners or those seeking mellow, forgiving conditions. The windiest periods come in February and December, which can chop up faces but also signal incoming swell energy.
Access is straightforward for most breaks, and the local vibe is welcoming to respectful visitors. The island's compact geography means you're never far from alternative spots if conditions don't match your skill level. Tourist infrastructure is solid, with good accommodation and food options throughout.
Based on WeWave data, Guam's peak season runs December through April, when average scores range from 37 to 40 and best-day potential reaches the low 80s. Summer offers the gentlest conditions with averages around 40 but much smaller waves averaging 0.7-0.8 meters, making it perfect for progression. Plan your visit around winter swells for the most exciting sessions, or come in summer for warm, manageable waves and uncrowded lineups.
