The Lowdown
Alright, Rusty here. Let’s talk about Triangulo for the next couple of weeks.
We’ve got a slow start, with nothing worth mentioning until Thursday the 13th. That’s when we finally see some energy. The water is running much warmer than usual for August, sitting at 71°, a pretty wild difference from what’s normal around here.
The best bet of the whole run is Friday the 14th. There’s a 1.3m SW groundswell with a 16-second period, so it’s got some long, clean lines. Winds are clean cross-off from the SSE, making the surface glassy. The combined energy is moderate at 1030 (moderate wave energy), and the swell direction is bang on what this reef wants. It’s not too big, and the consistency should be solid—this is the one to aim for.
We get another bump Tuesday the 18th, with waves hitting 2.1m from the SSW. The period drops to 13 seconds, and the wind turns cross-shore, creating a bit of chop. The energy is strong at 1490 (strong wave energy), but it’s not as clean as Friday the 14th. That size will also be for experienced surfers only.
From Saturday the 22nd, things fall off a cliff. Waves drop to 0.4m and stay there for days, with combined energy down in the 100s (weak wave energy). From the 22nd through the 25th, it’s basically flat and poor. You’re looking at a four-day dry spell.
There’s a small revival on Wednesday the 26th, and by Friday the 28th, we’re back to a 1.6m SW swell with combined energy hitting 1006 (moderate wave energy). Winds stay light and cross-shore, so the end of the period might actually offer a few decent, clean waves again.
Triangulo is always a bit inconsistent and rare to break, so when it does fire, it’s a special spot. But you gotta be patient and pick that Friday the 14th slot.
Rusty.

Information about the Triangulo Surf forecast
The above surf forecast table for Triangulo provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Triangulo can be found by selecting the local surf guide option on the grey menu. Our Triangulo surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Triangulo) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Triangulo may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
Triangulo is 7 km (4 miles) from the city of Lima. If you plan a holiday in Lima, look for hotels and other accommodation in Lima. Lima has rooms for a wide range of budgets as well as car hire and transport links.
