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 1.4m). Next neap on Tue 19 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.

Punta del Diablo sits at the northeastern corner of Rocha Department, 20 kilometres south of the Brazilian border and about as far from Montevideo as you can get in Uruguay while still being on the Atlantic coast. It started as a working fishing village — the boats are still there, pulled up on the main beach — and over the past two decades it has added hostels, surf camps, and a summer economy built on budget travellers who can't afford Punta del Este or don't want it. The geography is straightforward: a small rocky point with beaches on both sides. The main beach (Playa de los Pescadores) faces northeast and is where the fishing fleet operates. The boats launch through the shore break and return the same way — the operation requires timing and muscle, and watching it in a larger swell is worth getting up early for. The southern beach (Playa Grande) faces east and south, picking up more swell from the South Atlantic. A reef break operates on the point itself in larger swells from the south and southeast, producing a right-hander that can be clean when the wind is offshore (from the west or northwest). This is not a consistent break — it requires swell size, direction, and tide to align — but when it works it is the best wave in the immediate area. The tidal range is 0.7 to 1.0 metres at spring tides. The mixed semidiurnal cycle means two sets of high and low water each day, though they are not equal. For surfers, the reef break on the point is most defined at mid-to-low tide, when the reef is shallow enough to shape the wave without it closing out. The beach break on Playa Grande works at most states of tide but is most consistent around mid-tide when the banks are covered but not drowned. The community has changed fast since the early 2000s. It was genuinely isolated until the late 1990s — unpaved roads, no consistent electricity, three months of summer and nine months of fishing. Now there is reliable electricity, a paved road in from Chuy, and enough winter visitors that a handful of places stay open year-round. January brings 20,000-plus visitors to a village whose permanent population is around 200. The infrastructure strains: water, waste, and beach access all show the pressure during peak weeks. In February after Carnival, the village empties fast and the beach returns to the fishermen. Santa Teresa National Park sits 20 kilometres north, and the Portuguese fort there (built 1762, captured by Spain in 1793) is one of the oldest preserved military structures on the Uruguayan coast. The park has a campsite, a swimming pool complex, and trails through native Atlantic Forest. It is operated by the Uruguayan army and is open year-round. The combination of beach, fort, and forest makes it a logical day trip from Punta del Diablo — bring a vehicle, as public transport between the two is infrequent. Accommodation ranges from hammock-in-the-hostel to basic posadas. Most places are within 200 metres of one of the beaches. In summer, booking ahead is mandatory; outside January the options open up and prices drop. The restaurants do fish well — the catch comes off the boats on the main beach and is in the kitchen the same morning. Chivito (Uruguay's national sandwich — steak, egg, ham, cheese, salad) is a staple at any hour. Water temperature runs 18 to 23°C in summer and 12 to 16°C in winter. The prevailing wind is from the southwest and south, which can be strong and cold in winter, but makes the east-facing beaches relatively sheltered from the worst of the weather. In summer, light thermal winds from the land in the morning give way to sea breeze in the afternoon. For transport, most people arrive by bus from Montevideo (4 to 5 hours) or by car via Ruta 9 and then the coastal road east. The bus drops at Chuy (23km north), and a connection or taxi covers the last stretch. Bicycle rental is available in the village in summer. Predictions on this page come from Open-Meteo Marine, a gridded global ocean model. Accuracy is typically within plus or minus 45 minutes on timing and 0.2 to 0.3 metres on height — model-derived, not from a local gauge. The nearest reference station is the Argentine Servicio de Hidrografía Naval (SHN) Buenos Aires gauge; Uruguay's DINAMA does not operate a local tide gauge at Punta del Diablo.
