The Lowdown
G’day, Rusty here. Let’s talk about Triangulo. It’s an inconsistent reef break, so it needs everything to line up, and this 16-day window is a mixed bag. The water temp is sitting at 72°, which is way warmer than usual for this time of year—more than 9° above average, so it’s pretty unusual. Initially, there is a brief moment of hope right at the start, on Wednesday 29 July afternoon. We’ve got a SW swell around 5 ft, period 13 seconds—that’s a nice groundswell—with combined swell energy at 740 (moderate). The wind is light cross-shore at 6 mph. It’s rideable, but the forecast calls it marginal due to tide. It’s not a standout, but it’s the only session that gets anything close to okay early on.
Then we hit a long gap. Thursday 30 July morning cleans up a little—same SW swell, 4 ft, 12-second period, with light S winds at 6 mph going cross-offshore. That’s clean. Combined energy at 589 (moderate). This is the only window in the first week that scores well for conditions. The swell direction matches the optimum SW direction, and the wind is light and favourable. It’ll be small but tidy, and since the break is inconsistent and often crowded, you might have company. That Thursday morning is the best on offer for this entire outlook.
From Thursday afternoon onward, it goes downhill fast. Through Friday, Saturday and Sunday, the swell drops and the wind picks up, with moderate breezes and cross-chop messing things up. There’s not much to get excited about.
The second week has more swell energy but it’s plagued by cross-winds and marginal conditions. On Thursday 6 August morning, we see a big jump in combined energy to 1078 (strong)—a SW groundswell at 4 ft with a very long period of 17 seconds. That slow, powerful energy is best for a reef break like this, but the wind is a gentle cross-shore, not offshore, and the tide conditions are questionable. It’s promising but uncertain—worth watching if the wind shifts. Friday 7 August morning has 5 ft SW swell at 14 seconds, combined energy at 1071 (strong), with light cross-shore winds. Still marginal.
Honestly, the only session I’d paddle out for without hesitation is Thursday 30 July morning. Everything else is either too small, too choppy, or too marginal. Keep an eye on that long-period pulse around 6–7 August, but don’t clear your schedule yet. The break is inconsistent and this stretch shows why. Still, the water is warm and the forecasts can always change.
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.
