The Lowdown
Alright, Rusty here. Let’s see what this place is serving up.
Honestly, the first week and a half is pretty flat and messy. The water at Triangulo is sitting at 71°, which is far warmer than normal for this time of year – that’s a solid 9° above average, so it’s noticeably warm to the touch. But the surf… it’s mostly marginal, with a lot of cross-chop and poor conditions. Swell energy is weak to moderate, hanging in the 400s and 500s for days, with short-period windswell around 8 to 14 seconds. Nothing really worth paddling out for until we see a change.
The first real glimmer comes on Monday, August 10th. That morning, we see a nice jump in energy reading 1049 (moderate), with a clean, cross-off breeze. Swell is 3ft from the SW, but the period jumps to 18 seconds – that’s proper groundswell energy, offering some shape and power. It’s on the smaller side, but with those clean winds, it’ll be your best bet in this whole window. Triangulo is a sheltered reef, inconsistent, and often crowded – so if you want a piece of that Monday morning glass, get in early. The afternoon holds similar energy at 1006 but with a shorter 13-second period.
After that, it’s back to mediocrity through the middle of the month. There’s a bump in energy around Friday, August 14th, with readings pushing 1176 in the morning and 1048 in the afternoon, but the winds are cross-on, making it messy. Swell sits around 4ft from the SW, period 16 seconds. It’s a bit of a tease – there’s some grunt, but the quality isn’t there.
Monday, August 17th, shows another spike in energy: 1132 in the morning with 4ft SW swell, 16 seconds, but the wind is onshore from the W. Clean it ain’t. The afternoon drops a little to 1032, period 15 seconds, but the wind swings cross-on from the SW. Still, if you’re really desperate, there might be a few that stand up, just won’t be pretty.
Forget the rest of the second week – it’s back to light cross-shore junk and poor surf. The best on offer in this entire 16-day run is that Monday, August 10th morning session. It’s not big, but it’s clean, and at a location like this, that’s the standout.
Rusty, signing off.

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.
