The Lowdown

Alright, Rusty here again. Let’s look at it in feet and miles per hour.

The next two weeks at Triangulo look like a total bust. We’re looking at a long stretch of tiny, weak swell and poor conditions. The first real chance to get wet is on Thursday the 10th, but even that’s a stretch.

Thursday the 10th brings a 4ft SW groundswell with a 15-second period. That’s proper energy, coming in at a 774 combined energy. The water temp is 69°, a lot warmer than usual. The wind is a light cross-shore in the morning, turning to a clean cross-off in the afternoon. It’s an inconsistent reef, so you’ll be waiting between sets.

Friday the 11th and Saturday the 12th get worse. The swell is a bit bigger at 5ft to 5ft, but the period drops to a weak 8 seconds. That’s junky windswell with onshore wind. Skip it.

Then we hit a real flat spell. From Sunday the 13th through Saturday the 19th, it’s tiny. Swell runs from 2ft to 4ft, but the wind is messy and the conditions are constantly poor. Hardly any clean windows.

Sunday the 20th offers a slight pulse. A 5ft S swell with an 8-second period and a clean cross-off wind in the afternoon. It’s marginal, but it’s the best you’ll see in that whole week.

The final week, from Monday the 21st onward, is more of the same: 2ft to 3ft SW groundswells with long periods (up to 21 seconds). The energy is low, and a long-period groundswell this small won’t break with any power. It’s more of a ripple than a wave.

The one true standout? There isn’t one. The Thursday the 10th afternoon is your closest bet if you’re desperate. The 4ft wave is small, but with clean conditions and a long period, you might get a few good ones if you’re patient.

Honestly, this is a long, dry run. A lot of us will be sitting on the beach watching the tide come in and go out. Forecasts can change, but for now, this is about as quiet as it gets.

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.
