The Lowdown
Alright folks, Rusty here. Grab a coffee and let's have a look at what's on the cards for the next couple of weeks. We're looking at Triangulo, a reef setup that's a bit inconsistent and only really works when the swell direction swings to the southwest. Don't expect a whole lot of clear-cut winners, but there are a few windows worth paddling out for.
The first real chance of the period rolls in on Tuesday, the 14th. It's a morning session, and it's the standout of the whole forecast. You've got a clean 4ft of SSW swell rolling in at a long 13 seconds, which is a proper groundswell. The wind is a light 6 mph cross-off from the SSE, so the surface will be glassy. The water is a very unusual 70°, which is a massive 7° warmer than normal for this time of year – you won't need a thick wetsuit, that's for sure. The combined energy is moderate at 744. This is the best on offer, and it's in the morning, so be there early.
The rest of that first week is a bit of a grind. From Wednesday the 15th through to Sunday the 19th, the swell hangs around the 4ft to 5ft mark, but it's mostly cross-shore winds, and the forecasts are only marginal. The energy dips a bit, and while the size is okay, the conditions aren't quite coming together for a top-tier session. The morning of Saturday the 26th sees a drop to 5ft with a light cross breeze, which could be a nice clean session if you're keen.
Now, looking into the second week, things get a bit more interesting but also a lot more uncertain. The morning of Thursday the 23rd is a warning sign: a 6ft swell from the SSW, but with a short period of 9 seconds and onshore wind, that's a junky, messy wave. The afternoon of the 23rd jumps to a hefty 7ft from the S with a combined energy of 1308, but that's bigger than 5ft so it's getting into expert territory, and the moderate 12 mph cross-shore breeze will chop it up.
The real dark horse of the second week is the morning of Saturday the 25th. That's a solid 6ft SSW groundswell with a very long 13-second period, giving a combined energy of 1294. The wind is just a light 3 mph cross-on, so it'll be clean. At that size, it's a reef setup, so it could be a proper beast. But, it's a long-range call, so keep your fingers crossed.
After that, the swell fades. By the 28th and 29th, we're back to small 2ft to 3ft swells, and while the period is very long (up to 16 seconds), the energy is weak. It's not really worth the paddle.
So, the bottom line: the morning of Tuesday the 14th is your best bet for a clean, fun session. The morning of Saturday the 25th is the one to watch for the bigger stuff, but don't book the day off work just yet. For the rest, it's a waiting game.
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.
