The Lowdown
Alright, grab a coffee, I'll get you through this stretch. It's not going to be all-time, but there's a few windows where we might get something.
Right now, looking at the whole run, we've got a pretty flat and crummy start. Wind is from the wrong angles, and the swell is tiny and messy. You'll be sitting there staring at a lake.
The only break we've got to work with is Tres Picos. The water is sitting at a very unusual 71°, which is much warmer than normal for this time of year. That's nice for a paddle, but it doesn't make up for the surf.
Monday the 17th is a write-off. Swell is only around 4ft from the SW but with a cross-on breeze at 12 mph, it's just going to be choppy junk. Wave energy is moderate at best (800), and the call is poor.
Tuesday the 18th is a bit of a tease. The morning shows a 7ft SW swell, period dropping to a reasonable 13 seconds. Combined energy jumps to a solid 1383, but the cross-shore wind keeps it messy. It's marginal—worth a look at the right tide, but don't expect perfection.
Wednesday the 19th is still cross-on, with 7ft SSW swell. The period is dropping fast (10 seconds), so the waves will be weaker and lumpy. Not your day.
The end of the first week into the second week is basically a flat spell. From Thursday the 22nd through to Monday the 25th, we're looking at tiny waves (1ft to 3ft) and hardly any energy behind them. It's a proper drought. Time to fix your gear or find a hobby.
Now, here’s where it gets interesting for the patient surfer. The end of the run—Saturday the 29th of August—is worth a mark on the calendar. The morning brings a 7ft SW swell with a period of 15 seconds. That's a proper groundswell with real push. Combined energy hits 2117, which is strong. The wind is a light cross-on from the south at just 9 mph, so it’ll be fairly clean. This is the standout of the whole outlook. For a spot like Tres Picos, that longer period swell will wrap in nicely. The swell is 7ft—solid intermediate stuff, but bigger than what a beginner wants. Keep a close eye on this one.
Friday the 28th afternoon is also worth a mention. It's a promising lead-in, with 4ft at 17 seconds, giving 1071 energy. Cleaner winds and that long period will mean glassy lines for the evening session. It’s a great warm-up for the weekend.
Right at the very end, Tuesday the 1st of September, the swell jumps big to 10ft from the S, but the period drops to 9 seconds. That's a wall of wind-swell and it'll be closing out hard at this spot. The wind and tide might be okay, but this is getting into serious, expert-only territory. If you’re not on it, stay out of the way.
Overall, there’s a big gap of nothing, but a standout weekend at the end of August. Keep your eyes on that Saturday the 29th.

Information about the Tres Picos Surf forecast
The above surf forecast table for Tres Picos provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Tres Picos can be found by selecting the local surf guide option on the grey menu. Our Tres Picos 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 (Tres Picos) 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 Tres Picos 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.
Tres Picos is 3 km (2 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.
