The Lowdown
Alright, Rusty here with the same look, but in feet and degrees Fahrenheit.
We’ve got surf starting on Wednesday the 19th of August and it stays on the menu through the whole 16 days, though some sessions are much better than others. Swell comes from the SSW and SW, and the water is right around average for August, nothing to write home about.
The highlight is the morning of Friday the 28th of August at Tetitlan. We’re talking a 5ft swell from the SW, 17-second period, with combined energy at 1091 (moderate to strong). The wind is glassy out of the WNW – absolutely clean. The guidance says excellent for experienced surfers, and it’s true. That’s a powerful, long-period groundswell. At that size, it’s for experts only. The long period means the waves will be well-shaped and powerful, but at a point or reef like this, it’s the real deal. Crowds are possible, so don’t expect it to yourself.
Another great call is Saturday the 22nd of August morning. Glassy conditions, a 3ft swell from the SSW, 14-second period, combined energy of 524 (moderate). That’s clean, fun-sized surf – nothing big, but with the glassy wind it’s going to be a beautiful session. The word is “very good surf conditions.”
The first week also has clean mornings on the 19th, 21st, and 23rd, but those are smaller – 2ft to 3ft – so good for a longboard or a relaxed paddle, but not going to blow your mind.
From the 29th onward, the swell jumps to 5ft to 6ft, but the wind turns cross-shore or onshore and there are storm risks. Skip it. Then around the 1st and 2nd of September, we get another solid pulse of 4ft to 5ft from the SW with clean, cross-off winds from the east. That’s a promising long-range call – not as good as the 28th, but still a clean, solid option.
So for the experienced crew, lock in the morning of Friday the 28th of August. Glassy, 5ft, long-period groundswell. That’s the one. Just remember, it ain’t a secret spot.
Rusty.

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