The angler tradition for major/minor fishing windows: major ≈3-hour windows around moon transit and opposition; minor ≈2-hour windows around moonrise and moonset. Times are Pacific/Guam local. Folk tradition, not a scientific forecast.

Last spring tide on Tue 19 May (range 1.0m). Next neap on Fri 22 May.

Spring tides cluster around new and full moons (biggest swings). Neap tides land on quarter moons (smallest swings). See the spring tide and neap tide glossary entries for the why.

Pago Bay opens on Guam's east coast toward the Philippine Sea, facing northeast with direct exposure to the trade wind swell that wraps around the island's northern tip and arrives from the open Pacific. The bay is framed by steep basaltic and limestone headlands — the mixed volcanic and coral limestone geology of central Guam — and backed by the Talofofo River drainage, which runs south from the central plateau through jungle to reach the sea at the bay's southern end. Talofofo Falls, 3 km up the river from the bay, is a multi-tiered waterfall accessible through the Talofofo Falls Park: a gondola lift from the parking area descends into the river valley, a water wheel marks the historical milling operation, and a swimming hole at the base of the falls is fed by the river year-round. The trail from the gondola terminus to the falls passes through the kind of jungle cover that hid Japanese soldier Shoichi Yokoi until his discovery in 1972 — 27 years after the war ended — in this same Talofofo River drainage. The discovery site is marked and interpreted in the park. The Gef Pago Cultural Village sits on the ridge above the bay and reconstructs the pre-contact and early colonial Chamorro way of life: latte stone house foundations (the characteristic ancient Chamorro limestone support pillars), traditional weaving and pottery demonstrations, and a historical narrative of the Chamorro people's experience through the Spanish colonial period, the American administration, and the Japanese occupation. Gef Pago is an active community organisation, not a static museum, and the programme changes seasonally. Sea turtle nesting occurs on the east coast beaches adjacent to Pago Bay — green and hawksbill turtles use the sandy sections of Talofofo Beach, primarily from May through October. The nesting is managed by the Guam Department of Agriculture Wildlife Division; nest markers are placed when nesting is confirmed and the marked areas should be kept clear. The east coast exposure makes Pago Bay Guam's most consistent surf environment. Northeast trade swell arrives from November through April; December through February sees the largest consistent northeast swell. The Talofofo Beach section produces the most rideable break, best at mid to high tide. In the flat summer months (July through September), the bay is calm enough for paddleboarding and kayaking. The Talofofo River mouth changes character with the tide — at spring high, saltwater influence reaches several hundred metres upstream; at spring low, the river dominates the mouth and the estuarine fishing zone is most active. Guam's mixed semidiurnal tidal regime produces a spring range of 0.5 to 0.8 m here. Predictions on this page come from Open-Meteo Marine (gridded model, ±45 min / ±0.2–0.3 m). The Talofofo Falls Park gondola lift is one of the more practical ways to descend 120 m into the Talofofo River valley without the steep trail. The gondola operates on fixed hours (check the park schedule before visiting); the descent gives views into the jungle canopy and the river valley that the trail does not provide. The swimming hole at the base of the falls is fed by the river year-round, freshwater and cool. Pago Bay is the largest bay on Guam's east coast, sheltered by headlands on both the north and south sides. The Pago River empties into the bay and the estuary carries significant flow after heavy rain from the limestone plateau inland. The combined effect of river discharge and tidal movement creates a brackish zone in the inner bay that is highly productive for certain fish species, particularly juvenile stage fish that use estuarine habitat. Shore casting from the rock points on both sides of the bay mouth is a popular local activity; anglers typically fish the last two hours of the incoming tide when baitfish are concentrated at the river plume edge. The bay's outer section is exposed to the northeast trade swell and sees moderate wave action on most days; swimming is better on the south side of the bay where the headland provides lee. The reef extending south from the north headland is accessible by snorkel from the north beach access track; visibility is best in the early morning flood before river discharge and suspended sediment reduce clarity. Kayakers from Talofofo Bay to the south sometimes paddle around the southern headland into Pago Bay on the flood and return on the ebb.
