The Lowdown
G'day, Rusty here. Let's get into it.
We've got a solid run of swell lining up for Playa Santa Teresa, starting this Thursday morning. The water is sitting at 86°, which is much warmer than what you'd normally expect for this time of year – a proper tropical bath.
Thursday morning, the 10th of September, is the call to get wet. It's glassy, dead calm, with a clean 4 ft SW groundswell rolling in at a very long 17 seconds. The combined energy is moderate (881). This is a proper long-period groundswell that will wrap in nicely, offering clean, well-shaped waves. Perfect for a beginner-friendly spot like this, but be aware that long period swells can sometimes make the take-off a little more critical at the peak. Thursday afternoon, the onshore wind kicks in, so make the most of the morning.
Friday morning, the 11th, is another beauty. There's a light NNE breeze at 3 mph, keeping it glassy. The swell holds at 4 ft from the SW, with a 16-second period. A great option for a late-morning session before the sea breeze gets messy.
The wave energy drops off a bit through the weekend. Saturday the 12th and Sunday the 13th stick around 2 ft to 3 ft, but with clean, glassy mornings. If you're just learning or want a longboard glide, the dawn patrols are your best bet.
We then have a bit of a lull early next week, but it's not total flatness. The swell stays small, around 2 ft to 2 ft, but with some very long-period SW swell (18–19 seconds) pushing through. Monday the 14th and Tuesday the 15th mornings are clean and glassy, but the waves won't have much push.
The real standout looks like it's shaping up for Wednesday the 23rd of September. That morning, the swell bumps up to 3 ft from the SW, with a 16-second period, and it's glassy. The combined energy hits a moderate 627. Then, things get interesting. The swell jumps to 7 ft on Wednesday afternoon, but it's a short-period windswell (8 seconds) and the wind is onshore. Thursday the 24th and Friday the 25th see the swell hold at around 6 ft to 7 ft, but the period is still short (7–8 seconds). This is going to be a big, lumpy, and generally messy wave. For the experienced crew, Friday morning the 25th of September is the pick: a 6 ft SW swell, clean offshore NE wind at 3 mph, and solid energy (1357). That's an expert-only window as the size is over 5 ft, and the short period will make it dumpy.
Overall, the best windows are the early mornings, particularly Thursday the 10th, Friday the 11th, and the promising glassy morning on Wednesday the 23rd. The end of the period is for the big-wave crew only.
Rusty, signing off.

Information about the Playa Santa Teresa Surf forecast

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.
