The Lowdown
Alright folks, Rusty here. Let's have a look at what the next couple of weeks are throwin' at us down at Playa Santa Teresa. It’s a bit of a mixed bag, but there are definitely some windows where you’ll want to be in the water.
The pattern starts off a bit slow this Sunday, August 30th, with a small 4ft SW swell rolling in, but it’s got that light onshore breeze making it a bit messy and marginal. Honestly, you’re not missing much. The real story starts Monday morning, August 31st. The swell drops a touch to 4ft from the SW, but the wind goes dead glassy, calm as can be. The water is sitting at 87°F, which is more than 4° warmer than usual for this time of year – that’s a real nice anomaly, you can leave the steamer at home. That morning session is clean, with a solid moderate energy level (398) from a groundswell with a 13-second period. That’s a quality wave for a beginner-friendly spot if you ask me. The afternoon turns to rubbish, so get out early.
Tuesday, September 1st, offers another glassy morning with the swell holding at 3ft from the SW at 12 seconds. It’s small but clean, a good option if you're just getting your feet wet. Wednesday the 2nd morning is the first real standout. The swell drops to 2ft, but the period jumps way up to 18 seconds, giving it that long-period groundswell feel. The combined energy is a solid 526, and with glassy conditions from the WNW, those little lines will be peeling. A long-period swell like this can be a bit tricky at a beach break, but when it’s this clean, it’s all about finding the right bank.
Now, hold onto your board, because Friday, September 4th morning is the highlight of this whole forecast. The swell bumps up to a solid 5ft out of the SW with a 17-second period. The combined energy hits 1348, which is a strong, powerful push. The morning is glassy with a slight WNW breeze. This is going to be an excellent session for the experienced folks – that’s a proper swell that’ll have some punch. Given it’s a consistent break, you’ll be sharing it, but it’s worth it.
Saturday morning, September 5th, is another absolute cracker for the crew with some time. Swell is a touch bigger at 5ft from the SW, still with a 16-second period, and the energy is a hefty 1344. Glassy conditions again. This is top-tier stuff, but at 5ft it’s getting into the zone that’s a bit much for beginners. The following Sunday and Monday mornings hang on with clean but smaller surf in the 4ft to 4ft range.
Fast forward to the second week, and things get a little less certain but still promising. Around Wednesday, September 10th morning, you’ve got another solid opportunity with a 3ft SW swell at a very long 18-second period and a glassy NNE breeze. The energy is a moderate 917. Glassy and long-period means clean, lined-up waves. The following Friday morning, September 12th, offers a clean 4ft SW set with a 16-second period, and the wind is dead calm again. Good, clean fun for a quick morning paddle.
The pattern finally fades out towards the middle of September with smaller, cleaner mornings in the 2ft to 3ft range, still with that SW direction. The afternoons are largely a write-off with onshore winds or storms, so focus on the early windows. For a spot this consistent, even the quiet periods have their charm.
Catch you in the lineup.

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.

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).
