The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the cards for the next couple of weeks.
We're looking at a stretch that starts with a bit of a pulse, but honestly, it's gonna be a long grind for anything truly clean. The standout window is this weekend, Friday the 28th of August right through to Sunday the 30th, with a solid drop in energy after that. The water is sitting at a very unusual 68°F, which is a whopping 6° warmer than normal for this time of year – you'll feel that difference for sure.
The only break on the menu is Triangulo, a sheltered reef setup that's inconsistent and often crowded. It needs a south-west swell, and it's getting it. The best bet is gonna be Friday the 28th afternoon. We've got a 7ft south-west swell (strong wave energy at 1960) with a very long 15-second period. Winds are a gentle cross-shore, so it'll be a bit chop-ridden, but that's the biggest push of the window. It's over 5ft, so it's not for the learners, but the long period means proper groundswell lines. The quality is a bit marginal, but it's the biggest.
Saturday the 29th is your next best call. Early morning will see a 6ft south-west swell (strong energy at 1325), still a long 14-second period, and a light cross-shore wind. That light wind is a big positive, making it cleaner than the day before. It's still solid, but the energy is dropping. Saturday afternoon holds up with 6ft, and Sunday morning with 5ft, but the wind stays cross-shore and the period drops, so the shape gets a little less special.
After that, the swell drops below 5ft and the energy drops into the hundreds (from 753 down to 400). The period stays long, which is nice for shape, but the size is just weak. There's a gap of a few days in the middle of the week where it's really thin, but the light winds keep things surfable, just not exciting. The whole second week is a slow slide of small, inconsistent swell with very few standout moments. The window from September 1st to 12th is a long, flat-feeling grind with poor surf conditions on many afternoons. The best you'll find in that second week are the mornings of the 4th and 5th of September, with a 6ft and 5ft swell, but the consistency is just not there for a real score.
Overall, don't sleep on this weekend. It's the only real punch of the whole outlook.
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.
