The Lowdown
Alright, let’s talk about Playa Santa Teresa. First couple of days are a bust—Sunday and Monday have messy cross-onshore winds and weak surf. The water’s at 87°F, which is way warmer than usual—you’ll be surfing in board shorts.
Things clean up Monday afternoon (September 7th) when the wind goes glassy and we get a 3ft SW swell with a 13-second period. It’s small but clean—combined energy is moderate at 378. Good for a cruise.
The real standout is Thursday morning, September 10th. Dead calm, glassy, and a 4ft SW groundswell rolling in at 17 seconds. That’s a very long period—lots of punch, clean faces, and combined energy hitting 881. This is your session. There will be longer waits between sets, but when they come, they’ll be worth it.
Friday morning the 11th is also glassy with a 4ft SW swell at 16 seconds (combined energy 701)—very good, just a bit less juice than Thursday. After that, the second week fades. Mornings like Tuesday the 15th (3ft SW at 18 seconds, glassy) are alright for a lazy paddle, but nothing special. The 21st Monday bumps up a bit (combined energy 534, 3ft at 18 seconds) but the cross-onshore wind ruins it.
Bottom line: Thursday the 10th is the one to wake up early for. The rest is mostly small and clean but unremarkable. Santa Teresa goes quiet sometimes—it’s part of the deal.

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.
