The Lowdown
Alright, let’s break this down for the imperial folks. This is Rusty, and we’ve got a solid 16-day run ahead at Playa Santa Teresa.
The water’s warm – 86°F – and that’s a touch warmer than normal for September. You’ll feel it.
Starting off Wednesday the 9th, we’ve got a clean morning with a 3ft SW swell, 16-second period, and a light cross-off Easterly breeze at 6 mph. Moderate energy (520). Easy paddling.
Thursday morning the 10th is the early highlight. Swell pushes to 4ft from the SW, period 17 seconds, and it’s glassy with just a whisper of SE breeze at 3 mph. Energy’s up (881). This is clean, lined-up, and the best of the first week. Friday morning the 11th is a repeat – 4ft SW, 16 seconds, glassy with a light NE wind.
Saturday the 12th dawns glassy and calm, but the swell drops to 3ft. Still worth it for a dawn session.
Sunday the 13th and Monday the 14th mornings stay clean but small, around 2ft to 2ft. Monday’s got a very long 19-second period, but it’s tiny. Longboard territory.
Wednesday the 16th morning brings back a 3ft SW swell, 16 seconds, with a clean cross-off NNE wind at 6 mph. Good energy (604).
The real standout is Sunday the 20th and Monday the 21st. Sunday afternoon sees a 3ft SW swell with a 19-second period, glassy with a light NE breeze at 3 mph. Energy is strong (997). Monday morning the 21st is dead calm, glassy, 3ft SW with an 18-second period and 903 energy. These two sessions are the ones to plan for.
Tuesday the 22nd morning is another glassy one – 3ft SW, 16 seconds, calm winds, with moderate energy (516).
After that, the second week fades. Thursday the 24th morning is small but clean – 3ft SW, 14 seconds, glassy with a light SW wind.
Mornings are the key. Don’t bother with afternoons. The standout is that weekend of the 20th and 21st.
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.

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.
