Alright, Rusty here. Let’s talk about what’s on the menu at Triangulo for the next couple of weeks.

First thing: the water is sitting at about 70° right now, and that’s nearly 7° warmer than usual for this time of year. That’s a big deal—feels more like summer than winter.

The surf is starting slow. The first week is mostly "marginal" with light cross-shore breezes and waves around 4 ft to 5 ft. The swell is coming from the SW to SSW with periods between 12 and 16 seconds, so there’s some nice groundswell character—moderate energy, with numbers like 679 to 899 (moderate). But the conditions just aren’t coming together for a full-blown session.

The first real chance is Wednesday, 15 July morning. Clean cross-off wind from the south at 10 km/h, and 5 ft of SW groundswell with a 13-second period. Combined energy at 650 (moderate). The reef will be clean, and the waves will have some shape. Keep in mind, this spot can get “often” crowded, so you won’t be alone. For a beginner reef, this is a nice, friendly size.

Thursday, 16 July morning bumps up slightly: 5 ft of SSW swell, 13 seconds, clean cross-off wind, energy at 802 (moderate). That’s a solid little window—get it early before the afternoon breeze picks up and adds a bit of chop.

Friday, 17 July morning is another clean one: 4 ft SSW, 12-second period, cross-off wind, energy at 539 (moderate). Not huge, but clean and rideable.

Now, the big standout: Sunday, 19 July. The morning shows 6 ft of SW swell with a 13-second period, combined energy at 1274 (strong), and light cross-shore wind. That’s a proper pulse—definitely over 5 ft, so it’s getting a bit much for beginners, but not yet expert-only. The afternoon holds 7 ft with 1280 (strong), still light cross-shore. This is your best window across the whole 16-day forecast. The swell direction matches the reef’s ideal SW direction, and the period gives it real power. It’s more than a week out, so treat it as promising but not guaranteed.

Monday, 20 July morning is still worth it: 6 ft SSW, 13 seconds, cross-off wind, energy at 1093 (strong). Clean again. But the afternoon goes to hell with a 20 km/h cross-shore breeze—get out before lunch.

From Tuesday, 21 July through Thursday, 23 July, it’s mostly poor or marginal with onshore winds and smaller swell—skip it.

Thursday, 23 July afternoon throws a curveball: a tiny 2 ft swell with a massive 22-second period, combined energy at 827 (moderate). That’s very clean, cross-off wind, but the size is tiny—fun for a log or a fish, not much else.

The 24th and 25th bring some bigger windswell: 7 ft from the south, but only a 9-second period. That’s lumpy, fat, and not doing this reef any favors.

The last day, Sunday, 26 July, drops to 6 ft–6 ft, still short period (9 seconds), and cross-on winds. Messy.

Bottom line: first week is marginal with some clean small windows on Wednesday 15 July, Thursday 16 July, and Friday 17 July. The real highlight is Sunday, 19 July—bigger, stronger, cleanest of the lot. After that, it fades. Triangulo doesn’t always fire, but when it does, it’s worth the wait.

Rusty, out.

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.
