The Lowdown

G’day, Rusty here. Alright, let’s have a look at what’s coming down the line for Playa Santa Teresa. This is a classic exposed beach setup, and the next couple of weeks have a few proper gems if you time it right, but there’s also a fair bit of dross to sift through. Water temps are feeling about average for this time of year, nothing weird going on there.

The pattern kicks off proper on Thursday 13 August with some small, long-period groundswell and glassy conditions in the morning, but it’s only around 2ft and the energy’s weak (137). It’s surfable if you’re desperate for a splash, but nothing to write home about. That afternoon the wind swings onshore and it goes to crap.

Now, Friday 14 August is where it starts getting interesting. That morning is a beauty – clean, glassy, and a lovely 4ft SW groundswell with a very long 18-second period. The energy’s ramping up (804), and the combo of that clean NE wind and a solid groundswell sets the place up real nice. This is not for the grommets though; that kind of period and size can make it a bit walled up on a beach break.

Saturday 15 August morning is the standout of the whole run. We’ve got a clean 5ft SW swell, again with a long 16-second period, and glassy ENE wind. The energy’s well into the strong zone (1004), and conditions are excellent. This is for experienced surfers only – over 5ft on a beach break gets pushy. Crowds are a possibility here, especially on a Saturday. It’ll be worth it, but don’t be surprised if it’s busy.

Sunday 16 August is still very good, with another glassy morning and the swell holding at 4ft SW with a 15-second period. That afternoon it stays clean with offshore wind, so a solid day all round. Monday 17 August keeps the goods going – a bit smaller at 4ft but glassy again in the afternoon, so more clean waves.

After that, the swell eases but stays rideable through to Thursday 20 August, with mostly glassy mornings keeping things tidy even though the size drops to 2-3ft. Then there’s a proper lull from Friday 21 August through to Saturday 22 August – tiny waves down to 1ft and very weak energy (90-193). Barely worth paddling out.

We see a little pulse again on Sunday 23 August with a very long 20-second SW groundswell, but it’s only 1ft. That clean offshore NNE wind helps, but it's a gutless affair. The following week from 24 August onward is mostly small, with waist-high sets at best and energy staying weak to moderate. The best of that second week looks to be Thursday 27 August morning, with a clean 2ft SW swell and a long 18-second period, glassy conditions (209 energy). It’s a far cry from the Saturday prior, but it’s clean and rideable.

If I had to pick, Saturday 15 August morning is the absolute pick of the bunch. Friday 14 August and Sunday 16 August mornings are strong runners-up. Get out there for that Saturday session – it’s the one.

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.
