The Lowdown
Alright, Rusty here. Let’s look at what’s cookin’ for the next couple of weeks.
Honestly, it’s a slow start for Triangulo. This reef is always a bit inconsistent, and the first few days are pretty rough. The water is 72°F right now, which is way warmer than normal for this time of year, so that’s a bonus.
The first chance is Sunday afternoon, July 26th, with a 3ft SW swell, but it’s crossed-up with a moderate breeze, combined energy at 823. Looks ugly. I’d stay on the beach.
Monday the 27th and Tuesday the 28th we get a bump to 4ft to 5ft from the SW, with a long period around 15 to 19 seconds. That’s classic groundswell for a reef, but the wind is cross-shore, keeping the waves bumpy. The combined energy hits 1110 on Monday afternoon, but it’s still only marginal.
The rest of the first week and into early August is flat-ish. The swell drops to 2ft to 3ft, energy sinks into the 300s and 400s. Not much to get excited about.
But here’s the one to wait for: Friday morning, August 7th. That’s the real deal. A clean 4ft SW swell, 14-second period, and the wind is glassy. Combined energy is 667, but that glassy surface will make it the best session of the whole run. That’s the standout.
After that, it’s back to the grind. Marginal waves, light wind, nothing special. But if you can wait for that Friday morning, it’ll be worth it.
Rusty out.

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.
