The Lowdown
Alright, let’s talk about Santa Teresa over the next couple of weeks. The real payoff sits right at the tail end of the window. Mornings hold the cleanest waves; afternoons get blown out by seabreezes from the SSW.
There is a dry spell with no morning sessions worth chasing from the weekend of August 23rd through to the early hours of Wednesday August 28th.
The standout is Saturday morning, August 29th. Santa Teresa sees a 5ft SW groundswell at a 16-second interval with glassy northwest wind. The combined energy is very strong (1081). This is in the expert zone—big enough to push around, but clean as anything. If you’ve got the skill, that’s your session.
The morning before (August 28th) is also clean: 2ft of SW swell with a 20-second pulse and calm north-northwest wind. Energy’s solid (578). The long period could make it a little straight at the beach, but it’s a nice option for a log.
Water temp’s about normal for the time of year.
Crowds can be a factor on good days here. Expect company on those premium early windows.
For beginners, the 29th is too big. The mornings from August 21st through 24th offer 1ft to 2ft clean glass, but the energy is weak to moderate (62 to 304). Those are longboard days.
Into the second week, the mornings on August 30th and 31st, plus September 1st, hold 4ft to 5ft SW swell with clean cross-off or glassy wind. Energy drops a bit but it’s still fun.
The final Thursday morning, September 3rd, delivers 3ft SW swell at 16 seconds with glassy west wind and 780 energy. That one looks crisp.
If you’re an experienced surfer, circle August 29th morning. Everything else is small or blown out by afternoon.

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