🏖️ Recommended Activities

Sea swimmingExcellent

At low tide the waters tend to be calmer.

📸
Natural PoolsExcellent

Access only within the 2 hours near the lowest tide.

Ask the skipper about the conditions.

🎣 Solunar Table

★★★★★
🌊A major period coincides with high tide today — excellent activity window.
🌗Last Quarter

Major Periods (2h)

17:40 – 19:40Moon overhead
06:11 – 08:11Moon underfoot

Minor Periods (1h)

11:25 – 12:25Moonrise
00:55 – 01:55Moonset

Based on the Solunar Theory (John Alden Knight): fish and wildlife tend to feed more during the periods when the moon is overhead or underfoot (major) and at moonrise/moonset (minor). The score considers the lunar phase and the crossing of major periods with the local high tide.

📘 About Guam Tide Forecast

With geographic coordinates of 13.43° N, 144.65° E, Guam is a key coastal reference in United States. Its tidal pattern is semi-diurnal (two high and two low tides per day), with a mean tidal range of 0.7m and spring tides reaching up to 0.8m. Oyster and shellfish farmers exploit the 0.5–1.5m range to alternate aerial exposure and submersion in their culture beds. Mariners in semi-diurnal areas benefit from two high-water windows each day to cross shallow bars or enter marinas. The speed and direction of tidal currents here vary seasonally with the region's prevailing winds. Check the official 2026 tide forecast for Guam here, including detailed monthly schedules, peak times, and daily metric swings. In September, Guam is in its autumn season, a key period for water sports, fishing, diving, and coastal navigation. Astronomical tables for this site are processed using tidal harmonic algorithms and adjusted for regional bathymetry.
