The Lowdown

Alright, let's get into it. This 16-day stretch is a bit of a mixed bag, so let's break it down.

We're starting off with a bit of a wait on Saturday the 8th. There's swell in the water around Triangulo, but it's messy and the tide's not playing nice. You'll see some 3ft of SW swell with a 13-second period, but the wind is cross and it's just not coming together for a proper surf. The wave energy is sitting around the 500 mark, which is moderate, but it's not doing us any favors. It's a no-go for a proper session, so maybe save your energy for later.

Sunday the 9th isn't much better. The morning's got a poor surf call with a shorter period, 9 seconds, and that's just not gonna have any push. The afternoon sees a bit more life with a 15-second period and 3ft, but the wind is still cross-onshore and it's keeping things lumpy. This is Triangulo, and it's an inconsistent reef, so we're really relying on conditions to line up. It's just not happening yet.

The real window starts to open up on Monday the 10th. The morning's still marginal, but the energy jumps way up into the 1038 range, which is moderate to strong. The swell is 4ft from the SSW at 14 seconds. It's a long-period groundswell, which is great for a reef like this, but the cross-shore wind is still putting a little chop on it. It's a scoreable wave, but you'll be fighting the texture a bit. The afternoon is similar, a touch smaller at 4ft.

Tuesday the 11th is where things start to get more interesting. The morning has a clean 4ft SSW swell at 15 seconds, but still, that cross-shore wind is there. The afternoon, though, bumps up to 6ft and the energy climbs to 1127. The wind is still cross-onshore, but the size and the period are starting to make Triangulo's shape shine. It's a big, powerful reef wave, and if you're comfortable on a bigger day, this is when it starts to get fun.

Now, Wednesday the 12th is the standout of the first week. The morning is the best we're gonna see for a while. The call is for good surf conditions. The wind shifts to a cross-offshore, cleaning up that 5ft SSW swell with a 13-second period. The energy is at 807, which is solid, and the clean face is going to make it proper. This is the one to point the car at. It's not huge, but it's clean, and on an inconsistent reef, that makes all the difference. This is your best bet for a proper session.

After that, it's a bit of a letdown. Thursday the 13th brings a long, 19-second period swell, but it's only 3ft and the wind is cross-onshore. The energy is moderate, but it's just not gonna have enough size to do much on this break. The rest of the week into the weekend is a series of marginal, small, and windy days. The size stays around 3-4ft, the wind stays cross, and the energy drops back down. There's a bit of a pulse on Sunday the 16th with 5-6ft and a clean cross-offshore wind, but the energy isn't as high as Wednesday, and the period is a bit shorter. It's worth a look, but it's not the same quality.

The second week is looking weaker. From Monday the 17th onwards, it's a drop-off. The swell stays around 4-5ft, but the winds get messier, and the energy starts to fade. There's a bit of a pulse around Tuesday the 18th, but the wind is onshore and it's just poor. By the 21st and 22nd, the energy is down in the 300s, which is weak, and the surf is poor. The long-range call for the 23rd shows a little bump back to 4ft and 667 energy, but it's still cross-shore and nothing to get too excited about.

So, to wrap it up: your clear standout is Wednesday morning, the 12th. That's the one with the clean, offshore wind and the solid groundswell. The Sunday the 16th afternoon has some potential if you're not fussy about the texture, but Wednesday is the day. The rest is a waiting game, and with Triangulo being as inconsistent as it is, you have to pick your moments. The water temp is about average for this time of year, so a good wetsuit is all you need.

Stay stoked, and pick your days.

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.
