The Lowdown
Alright, Rusty here. Let’s have a look at what’s on the cards for Playa Santa Teresa. The water is sitting at a balmy 87°—that’s much warmer than usual for this time of year, a real tropical treat.
We’ve got a solid run of surf ahead, starting right from this Sunday morning. The first session kicks off with a clean 3 ft of swell from the SW, with a period of 14 seconds. That’s a nice groundswell with decent energy (413). The wind is offshore from the NE at 9 mph, so the lines will be clean. Sunday morning is the pick of the day, but by the afternoon the wind swings cross-on and it gets choppy.
Monday morning, the 10th, looks alike: 3 ft from the SW with a 13-second period, light offshore breeze from the NE. Nice and clean. The afternoon turns onshore, so get out early.
The standout for the first week is shaping up to be Tuesday the 11th morning. Glassy conditions with the wind completely off—N at just 3 mph, and it’s glass. The swell is a clean 3 ft, 14-second SW groundswell, and the energy is solid (387). That’s going to be a really fun, clean session.
But if you want the real highlight of the whole forecast, wait for Friday the 14th morning. The swell jumps to 4 ft from the SW with a very long 18-second period. This is a proper groundswell, and the energy is pumping (804). Glassy conditions with a light N breeze. Saturday the 15th morning is even bigger, with 5 ft SW swell and a 16-second period, and the energy is strong (1004). That’s expert territory, but it’ll be glassy with a light NNE breeze. Both of those mornings are top-tier.
There is a gap in quality after the 15th, with the surf dropping back to smaller, more ordinary waves through the middle of the week. The 18th of August Tuesday morning brings a different swell – 4 ft but from the SSW with a short 8-second period, which will be a bit lumpy and disorganised, though it’s glassy. Not the same quality.
The second week sees a resurgence. The 22nd of August Saturday morning is small but promising: 2 ft from the SW, but with a very long 21-second period. That’s a long-range groundswell – will be insanely clean and glassy, with an ENE breeze at 3 mph. The 23rd Sunday morning is another gem: 3 ft, 19-second SW groundswell, offshore NE wind, and clean. Those are the ones to circle on the calendar, but remember, it’s a long way out so keep an eye on it.
Overall, the best of the best is Saturday the 15th morning for experienced surfers, and Friday the 14th morning for a slightly smaller, still excellent session. Get on it.
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).
