The Lowdown
Alright folks, Rusty here. Let’s have a good look at what’s coming down the pipe for Triangulo. It’s a bit of a slow burner, so patience is going to be key. The water is sitting at 69°, which is much warmer than normal for this time of year – you might not even need a full suit, just a springy.
Right now, we’re in a flat spell. The first few days from Saturday the 22nd through to Wednesday the 26th are a write-off for any decent waves. We’re talking tiny 1ft swell with weak energy (around 221), and the winds are mostly cross or cross-on, keeping things messy. You’d be wasting your time paddling out.
The first real glimmer of hope shows up on Thursday the 27th morning. The swell bumps up to 2ft, but the real story is the period jumping to 20 seconds – that’s proper long-period groundswell energy (478). It’s still marginal, and the light cross-shore breeze will keep the surface a little bumpy, but it’s a sign of things to come. This is a tricky one because that long period can make a sheltered reef like Triangulo stand up, but it’s inconsistent here, so don't expect a wave every minute.
Then things get serious. Friday the 28th is the standout. We’ve got a solid 6ft to 7ft SW groundswell rolling in with a 16-second period. The combined energy is pumping at 1960 to 2158 – that’s strong wave energy, and it’s gonna feel powerful. The wind is light and cross-shore, which is good for shape but not perfect. This is big enough that beginners should sit this one out; it’s in the expert zone at that size. The swell direction from the SW matches the optimum for this spot, so the reef should line up nicely.
The quality holds through Saturday the 29th with 6ft swell, still plenty of energy (1279), but the wind picks up a bit on the afternoon, adding some chop. By Sunday the 30th, the swell starts to dip, and a stronger SSE wind kicks in, so it’s getting sloppier.
Looking further out, there’s another promising pulse around Thursday the 3rd of September. We see another 6ft SW groundswell with an 18-second period, and light cross-shore winds. Energy is back up over 2000. It’s a similar setup to the 28th – big, powerful, and best for experienced surfers. This one’s a bit further away, so keep an eye on it, but the ingredients look tasty.
Overall, the first week is a bust, but the end of August and start of September offer two solid windows of proper, meaty SW groundswell. The standout is definitely Friday the 28th of August – that’s the day to circle on the calendar if you’ve got the skills for it.
Stay frothing,
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.
