The Lowdown
Alright folks, Rusty here. Let’s look at what’s coming up for Petatlan.
We’ve got a solid pulse of Southern Hemi groundswell rolling in right now, and the first week is where the real action is. Monday morning kicks things off with a clean 5.2ft SSW groundswell, period a very long 17 seconds, and glassy conditions. The combined energy is a hefty 2186 (strong). This is proper, powerful surf for experienced surfers only – at over 5ft and with that long period, it’s not for the faint-hearted. The water temp is about average for the time of year.
Tuesday morning looks like the standout. The swell bumps up to 6.6ft from the SSW, still a very long 17 second period, and the wind is dead calm. Glassy perfection. The energy readings are massive at 2529 (very strong). This is the one to circle. Again, this is expert territory at over 8ft, but if you’ve got the skills, it’s going to be unforgettable. The break is fairly consistent, but crowds are possible, so get in early.
The swell eases through Wednesday and Thursday, but Thursday morning still offers a very clean 4.6ft SSW swell with a 14 second period and glassy winds. The energy is 967 (moderate) – still a very good session for the competent surfer. Friday morning is similar, with 3.9ft SSW swell, glassy, and energy at 614 (moderate). Very good conditions.
Saturday and Sunday see the swell drop below 3ft, with choppy, cross-onshore winds. The energy drops to 283 (weak) by Sunday. It’s a bit of a lull, but the pattern doesn’t stay poor for long.
After a few days of small surf, we see a new pulse of SSW groundswell arrive on the morning of Friday, August 7th. The swell is 3.6ft with a 17 second period, glassy conditions, and energy at 980 (moderate). A very good, clean morning. The following Saturday morning, August 8th, is also glassy with a 3.9ft SSW swell (15 seconds, energy 824). A solid weekend option. The next morning, Sunday, August 9th, brings a light offshore wind from the NE with a 3.9ft SSW swell – clean and promising, though the energy is a bit lower at 640 (moderate). The week after that, the surf settles into smaller, glassy mornings with 3ft to 3.3ft SSW swell, good for a longboard or a fun cruiser. Remember, those long-period swells can be a bit straight at beach breaks, but they’ll be offering nice shaped waves here.
Stay stoked.

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.
