The Lowdown
Alright, Rusty here. Let’s talk about the surf at Playa Santa Teresa for the next 16 days. The water’s sitting at a balmy 87°, which is much warmer than what’s normal for this time of year, so you’ll be cooking out there.
We start off small. Wednesday morning the 12th has a long-period SW groundswell at 2ft with a 16-second period. The wind is light and cross-off, making for clean lines (combined energy 317). It’s a fun, small wave to get wet. The afternoons that day and all of Thursday look poor with onshore wind, so stick to the mornings.
Friday the 14th kicks things up. The swell comes in at 4ft from the SW, with an even longer 18-second period and glassy conditions. The energy is strong (804), and the surf is looking very good.
Now, the real standout is Saturday morning, the 15th of August. We’ve got a 5ft SW groundswell with a 16-second period and dead calm, glassy wind. The combined energy is pumping at 1004, and this is described as excellent for experienced surfers. That is your session. The water will still be that unusually warm. Because the period is so long, expect the sets to be a bit faster and straighter at the shore, but the face quality will be world-class.
Sunday the 16th is still a cracker, with 4ft of SW swell and glassy conditions in the afternoon. Energy is still high (606). Monday and Tuesday mornings (17th & 18th) keep it clean with offshore-ish winds and 4ft and 3ft swells respectively. Great follow-up sessions.
We hit a quiet patch mid-week (19th-23rd), with swell dropping to 1ft to 2ft and mostly onshore breezes. A few glassy mornings offer knee-high waves for a longboard, but it’s a definite lull.
The final highlight is a week away. On Thursday morning, the 27th of August, a new long-period SW groundswell arrives with 3ft surf and a 17-second interval. The wind is glassy, and the energy is strong again (552). It’s a way off, but it’s a good reason to keep an eye on the forecast.
The pick of the whole run is Saturday the 15th morning. Big, clean, and powerful. The weekend of the 16th-17th is also top-tier. The last week is quieter until that potential re-up on the 27th.
Rusty.

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.
