G’day, I’m Rusty. Let’s have a look at what’s coming up for Triangulo over the next fortnight and a bit.

Right off the bat, Thursday morning 2 July looks like your only real standout, and it’s a bit of a ripper. We’ve got a clean 5 ft SSW groundswell rolling in with a long 15-second period, and the wind’s a light cross-offshore from the SSE at 9 mph, so the surface will be glassy. The water’s sitting at 69°, which is a whopping 6° warmer than normal for this time of year – that’s very unusual, so it’ll feel like a tropical treat. The combined swell energy is pumping at 1370 (strong). This is a reef break, and with that long-period groundswell, the waves will have real shape and push, plus long lulls between sets making the paddle-out easier. It only breaks rarely though and is inconsistent, and it’s sheltered, so you need the right tide – but when it’s on, it’s on. Expect it to be too big for beginners at 5 ft. Crowds are often a thing here, so you might have company.

After that morning high, Thursday afternoon stays clean with the same 5 ft SSW swell and cross-off wind, but conditions become more marginal, likely due to tide. By Friday 3 July, the swell drops to 5 ft SSW at 14 seconds, but the wind turns cross-onshore and the combined energy drops to 975 (moderate) – the surf gets poor.

Saturday 4 July is smaller again at 4 ft SSW, with light cross-on winds and energy down to 844 (moderate), only marginal. Sunday 5 July sees a new 3 ft SW swell, but with a very long 20-second period and combined energy at 1341 (strong) – that long period will make it clean but maybe a bit straight at this reef break. The wind is cross-onshore in the morning, then cross-shore in the afternoon with clear skies. Still, the overall quality is only marginal.

Monday 6 July bumps back up to 5 ft SW at 17 seconds on the morning with offshore WSW wind at 6 mph, and the combined energy hits 1754 (very strong). This is a good window – offshore wind, solid swell – but it’s still only rated marginal, so something’s off (likely tide or break consistency). After that, the trend fades. From Tuesday 7 July through to the end of the forecast, we see a slow decline: swells hover between 3 ft and 5 ft, periods shorten into the 12-16 second range, and the combined energy drops to mostly two-digit or low three-digit numbers (weak to moderate). Winds stay mostly cross-shore or light cross-onshore, and nearly every session is marked as marginal or poor.

There’s a long gap from Friday 10 July right through to about Wednesday 15 July where nothing really offers any quality. On Wednesday 15 July morning, a tiny 2 ft SSW groundswell at 12 seconds shows up with a cross-off SSE breeze at 9 mph and energy at just 320 (weak) – surfable but very ordinary. Thursday 16 July brings a slight increase to 4 ft SW, but still only marginal.

Honestly, for this region, a blank run like this is more normal. Triangulo is an inconsistent, rarely-breaking reef that needs a lot of things to line up. The one bright spot is that Thursday 2 July morning window – if you can get on it, that’s the pick of the whole outlook. After that, you’re waiting a long time for anything decent.

Stay salty,
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.
