The Lowdown
Right, let’s have a look at what’s on the cards for Playa Santa Teresa. We’ve got a solid run of clean mornings ahead, especially for those who can get out early. The water temp is sitting about average for this time of year, so no surprises there.
The pattern starts off with a small but clean Monday morning, August 10. You’ve got a 3ft SW swell with a nice 13-second period and light offshore NNE wind at 6 mph. That’s a fun little combo, and the wave energy is moderate at 318. It’s not huge, but it’s clean and surfable. Tuesday morning, August 11, is even better – glassy conditions with a 3ft SW swell and a longer 14-second period. The energy steps up a bit to 387, and with 3 mph northerly winds, it’ll be smooth.
Wednesday morning, August 12, stays glassy with a 2ft SW swell and a 16-second period. The energy is moderate at 347, so you’ll get long waits but clean, lined-up waves. Thursday morning, August 13, is glassy again with a 2ft SW swell and 15-second period, though the energy drops to 178. It’ll be surfable but pretty ordinary.
Now, the real standout comes on Friday morning, August 14. We jump to 4ft of SW swell with an 18-second period – that’s proper groundswell. The energy is strong at 729, and with glassy conditions and 3 mph northerly wind, it’s going to be excellent. This is the pick of the first week, no question.
Saturday morning, August 15, pushes it further. 5ft of SW swell at 16 seconds, with offshore NNE wind at 3 mph. The combined energy hits 1004 – that’s strong stuff. This one is for the experienced crew, as it’s solid and powerful. It’s a close second to Friday, but still a cracker.
From Sunday, August 16, through the end of the second week, the pattern is a bit more mixed. The mornings generally stay the better sessions. Sunday morning is a 4ft SW swell with cross-shore wind, a bit messy. Monday, August 17, brings back glassy conditions in the morning and afternoon with a 4ft SW swell and 14-second period, energy in the 600s. That’s a couple of really good sessions.
The rest of the week sees the swell drop a bit. Tuesday morning, August 18, is 3ft with offshore wind, clean. Wednesday and Thursday mornings, August 19 and 20, are smaller again – 3ft and 2ft – but still clean. Then we hit a bit of a lull from Friday, August 21, to Saturday morning, August 22, with only 2ft to 2ft of swell.
But hold on – Sunday morning, August 23, fires back up. 3ft of SW swell with a 19-second period, glassy, and energy at 667. That’s a very long-period groundswell, which at a beach break like Santa Teresa can be a bit straight, but with no wind it’ll still offer some fun ones. Monday, August 24, is much the same story: 3ft, 18-second period, glassy, energy at 513. Tuesday, August 25, wraps it up with a 2ft SSW swell and glassy conditions.
Overall, the best on offer is Friday morning, August 14, with that 4ft 18-second groundswell and glass. Saturday morning, August 15, with the 5ft is the one for the experienced guys. Mornings are the key – afternoons are mostly blown out or onshore. Crowds are sometimes an issue here, so the early bird gets the cleanest waves.
Stay stoked.

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.
