La Pedrera, Uruguay tide times

Predictions: Open-Meteo Marine (MeteoFrance SMOC, 0.08° grid) — heights relative to MSL (not chart datum / LAT). Model-derived.

Model-derived from a global ocean grid. Useful indication; expect about ±45 minutes on average vs. a local harmonic gauge, individual stations vary widely. See /methodology for per-region detail. Not for navigation.

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 America/Montevideo local. Folk tradition, not a scientific forecast.

Next spring tide on Wed 20 May (range 1.1m). Last neap on Tue 19 May. Next neap on Mon 25 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.

La Pedrera occupies a clifftop above a long sandy beach between La Paloma to the west and Cabo Polonio to the east — a stretch of Rocha department coast that has remained less commercially developed than either neighbour. The village sits on a low headland of dark rock, and the road from the main highway arrives at a cluster of houses, small posadas, a handful of restaurants, and an unobstructed view southeast over the Atlantic. The appeal is deliberate simplicity: no large hotels, no nightclub strip, no organised beach concessions, and a local community of Uruguayan beach-goers who return each summer specifically because those things are absent. The beach below the cliffs runs for several kilometres in both directions. The eastern section narrows between the headland base and the dunes, creating a sheltered concave section that holds calmer water on most swell directions. The western section opens into the broader arc toward La Paloma and is more exposed to the prevailing south and southeast Atlantic swell. The cliff-base intertidal zone on the headland itself exposes rock platforms and boulder fields at low water, with tide pools holding the standard Atlantic South American fauna: limpets, mussels, small blennies, and occasional octopus in the deeper crevices. The tidal regime at La Pedrera follows the Rocha department pattern: a mixed regime with a spring range typically 0.5 to 1.0 metres. Two tidal cycles per day, but the signal is strongly modified by wind and barometric pressure. Southwesterly winds push Atlantic water up the coast, raising water level above astronomical tide predictions; strong norther winds (viento del norte) draw the water offshore and expose bottom well below predicted low water. The wind effect on water level routinely exceeds the tidal signal by 0.3 to 0.5 metres in either direction. For practical planning — rock platform access, vehicle beach driving, low-tide angling — the wind forecast matters as much as the tide table. Surfing is the activity most associated with La Pedrera. The headland creates a sheltered zone on its eastern lee side that allows light-wind conditions even when the coast opens to south swell, and the western beach section picks up the full south-southeast groundswell that travels north from the Southern Ocean. The point break off the headland tip works on a south to southeast swell with low-tide to mid-tide water level; the beach break to the west is more consistent across tidal states but less defined. The waves at La Pedrera are Uruguayan in character: not big (2 to 3 metres on a good swell day is notable), not perfect, but available consistently enough to sustain a year-round surf community. The natural environment between La Pedrera and Cabo Polonio to the east is one of the least-altered coastlines in Uruguay: active dune systems 10 to 20 metres high, seasonally inundated lagoons behind the dune line, and the south Atlantic forest coastal scrub. The Laguna de Rocha, a large coastal lagoon 15 kilometres west of La Pedrera, is a protected wetland with significant water bird populations accessible by kayak. Offshore, the Banco de la Paloma reef system supports artisanal fishing from La Paloma and La Pedrera, targeting sea bass (corvina negra), mullet, and shark. For photographers, the headland at sunset provides an unobstructed west-facing view with the beach in the foreground and Atlantic horizon behind. The cliffs below the village are 15 to 20 metres of dark volcanic and sedimentary rock, and the contrast between the dark cliff face and the white foam of the surf below is at its best in the two hours before sunset when the light comes from the west and rakes across the rock face. Tide predictions for La Pedrera come from Open-Meteo Marine, a global gridded ocean model. Accuracy is within plus or minus 45 minutes on timing and 0.2 to 0.3 metres on height. Given the wind dominance of water level variation on this coast, the actual water level on any given day may differ from the astronomical prediction by more than the stated model accuracy; treat the predictions as a tide phase guide and observe actual conditions.
