The Lowdown
Alright, this is Rusty. Let’s have a look at the surf ahead for Petatlan.
Alright, listen up. We’ve got a solid run of swell coming in, but it’s for the experienced crew only. The water is a touch warmer than normal for this time of year, sitting at 88°F, so that’s a nice bonus.
The best bet on the whole forecast is Monday morning, July 27th. We’ve got a solid 5ft SSW groundswell with a long 17-second period, pumping a ton of energy (2186). The wind is glassy, totally off the land, and it’s going to be clean as a whistle. This is prime time for those who know what they’re doing. The swell direction is spot on from the south, feeding right into the break.
Tuesday morning, July 28th, is also a standout. The swell is up a touch to 7ft from the SSW, with a 17-second period as well, and the energy is huge (2583). The wind is dead calm – glassy perfection. This is a big, powerful wave, so only for the experts. The morning will be the window before the afternoon cross-off wind tidies it up for the afternoon session too.
Wednesday morning, July 29th, is another glassy morning, with 6ft of SSW groundswell (1829 energy). It’s perfect for those who want a slightly smaller but still very powerful wave.
After that, the swell starts to back off. Thursday, July 30th, and Friday, July 31st still have some clean, glassy mornings with 5ft and 4ft SSW swells, but the energy drops off significantly into the 600-1000 range. It’s still fun, but not the main event.
The following week, from August 1st through August 6th, it gets small and messy. The swell drops below 3ft, and the winds are a cross-shore mess, so you’re looking at a lot of weak, choppy surf. There’s a window on Monday morning, August 3rd, with a glassy 3ft, 14-second swell, but it’s very low energy (318). Not worth a special trip.
Then, on August 7th, we see a new pulse of SSW groundswell. The Friday morning, August 7th, has 3ft at 17 seconds with glassy conditions (791 energy), and Saturday morning, August 8th, is similar with 4ft at 15 seconds (832 energy). These are promising, clean mornings, but it’s a week and a half away, so keep an eye on it.
Monday morning, August 10th, is the tail end, with a tiny 3ft, glassy morning but very low energy (283).
Overall, the first few days are the real deal. Don’t sleep on that Monday (July 27th) or Tuesday (July 28th) morning. The rest of the month is for the patient or the beginner who just wants a splash.

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