The Lowdown

Alright, Rusty here. Let's have a look at what's coming down the pipe for our local zone.

First up, the only break on the radar is Triangulo, a sheltered reef setup that's known to be inconsistent. Over the next 16 days, the surf window is pretty tight and honestly, most of it looks like a struggle. We've got a long stretch of poor conditions ahead, so don't expect any fireworks.

Things start off on Monday, September 7th, with a small SW groundswell. We're looking at a combined wave energy of 670 (moderate) in the morning, with a clean 3ft swell riding a long 16-second period. That long period is a good sign for a reef break like Triangulo – it'll produce some lined-up, shapely waves, but the sets will be widely spaced. The wind is light and cross-shore, keeping the surface clean, but the overall forecast is marginal with questionable tide. The afternoon pushes the swell to 3ft with energy at 704, still with that clean, light cross-shore breeze. It's not big, but for a beginner-friendly inconsistent spot, this is the most promising window we've got. The water temp is about average for this time of year.

Tuesday the 8th sees the swell bump up a touch to 4ft-4ft, period dropping to 14 seconds, but the wind stiffens from the south at 9 mph, putting a bit of a cross-chop on the surface. The morning is marginal, but the afternoon is rated as poor. By Wednesday the 9th, we're into the poor category with stronger cross-shore winds and a messy surface. The swell hangs in there around the 3ft mark, but the quality is gone.

From Thursday the 10th right through to the end of the forecast on September 22nd, it’s a bleak run. We bounce between marginal and poor surf conditions daily. The swell height fluctuates between 1ft and 4ft, but the wind is almost always from the south or southwest, leaving the surface chopped up or cross-onshore. Most of the combined energy drops into the 200-600 range (weak to moderate), and the period varies wildly from a short, weak 8-second windswell to some longer-period groundswells that never get a clean wind window.

There is no standout day here. The best you can hope for is to maybe catch a wave or two on Monday the 7th, either morning or afternoon, when the winds are lightest and the swell is cleanest, even if it's small. For the rest of the run, it's a wait-and-see game. Forecasts can always change, but as it sits right now, it’s a tough outlook for paddle surfing.

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.
