The Lowdown

Alright, listen up. Rusty here. Let’s talk about what’s on offer for this stretch.

We’re looking at a break called Triangulo, a sheltered reef that’s inconsistent and rarely works. Over the next 16 days, it’s a long, slow grind of small, average waves. The swell never really fires, and the wind is a constant pain. There’s a gap at the start, with the first real surfable bit not showing up until Monday, July 27th. Before that, it’s all knee-high and messy.

The water is warm – 72°, which is far warmer than usual for this time of year. That’s a strange one, but you’ll be comfy in a shorty.

The first week is mostly a wash. From Thursday the 23rd through Sunday the 26th, it’s all waist-high slop with cross-shore and cross-onshore breezes. The combined energy is weak, between 566 and 888 (moderate), but the quality is just not there. It’s a tease.

The best of the bunch is Monday, July 27th. The afternoon session sees the swell push to 5ft from the SW, with a period of 16 seconds. That’s real groundswell – long, powerful lines. The combined energy jumps to 1224 (strong), and the wind goes light and cross-shore, which will clean things up nicely at a sheltered reef. This is the one to aim for. It’s too big for beginners, and because it’s an inconsistent reef, it’s one of those rare days where it might actually line up. Crowds are often a problem here, so expect company.

Tuesday the 28th holds similar size at 5ft from the SW, period 15 seconds, with a clean cross-offshore breeze in the afternoon. Another solid day, but by Wednesday the 29th, the period drops back to 13 seconds and the size starts to fade. The rest of the week into early August is a slow downhill slide. The swell drops back under 3ft, periods get shorter, and the wind goes onshore or cross-onshore again. By Saturday, August 1st, it’s flat and poor.

The second week is a waiting game. There’s a little pulse of energy on Thursday, August 6th – 4ft from the SW with a period of 13 seconds, but the wind is tricky. And then on Friday, August 7th, we see a longer period swell (18 seconds) from the SW, with combined energy of 1147 (strong), but the wind is a moderate cross-shore, likely creating some chop. It’s a distant hope, not a sure thing.

Bottom line: The surf is generally poor for most of the window. The only real standouts are the afternoon of Monday, July 27th, and Tuesday, July 28th. If you’re not an expert, skip the bigger days. This is a spot that’s usually quiet, so when it does get a pulse of long-period groundswell with light wind, it’s a rare treat. But don’t count on the long-range stuff.

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.
