The Lowdown

G’day, I’m Rusty. Let’s have a look at what’s comin’ for Playa Santa Teresa over the next couple of weeks.

We start off with a bit of a mixed bag. The first real standout hits you right away on Friday morning, 21 August. Swell is 4 ft from the SSW with an 11-second period, and the water is 87° – that’s much warmer than normal for this time of year. The combined energy is moderate at 434. Winds are glassy from the NNW, so the surf is clean and inviting. This is a consistent spot, so you can expect some fun waves rolling in.

The afternoon turns onshore with a SSW wind at 15 km/h, and conditions drop off quickly. Saturday morning, 22 August, is small and glassy again – 2 ft from the SW with a long 14-second period, but it’s weak energy at 101, so it’ll be a bit lackluster. Sunday morning the 23rd picks up a bit with 2 ft from the SW and a very long 19-second period, giving clean waves thanks to a cross-offshore ENE breeze of 10 km/h, energy at 304.

Monday morning the 24th sees 2 ft from the SW with 18-second period, light offshore NE wind at 10 km/h, and clean conditions again. Energy is moderate at 271. Not big, but workable.

Tuesday the 25th brings another glassy morning – 2 ft SW swell with 16-second period and NE wind at 5 km/h, energy at 202. Keep the small-wave board handy. Wednesday the 26th is even smaller: 2 ft from the SW with 15-second period, glassy NNE breeze at 5 km/h, but only 146 energy. It’s ordinary, but surfable.

Now, Thursday the 27th morning – things get a little hectic. Swell jumps to 6 ft from the SSW but with a short, crumbly 7-second period, and a cross-offshore ESE wind at 15 km/h. Energy is 500, and it’s marginal. Not the best for paddle surfing – this setup starts to look more interesting for kiteboarding.

Friday the 28th is messy with cross-onshore winds and lumpy conditions. Not your day.

Here’s the first true standout of the whole outlook: Saturday morning, 29 August. We get 5 ft from the SW with a solid 16-second period, and the wind goes glassy from the NW at 5 km/h. The combined energy hits a strong 1170. This is excellent for experienced surfers – the size and power are there, and the glassy wind means clean faces. The swell direction matches the optimum from the WNW, so the break will light up. This is a beauty.

Sunday morning the 30th stays solid with 5 ft SW swell, 14-second period, and glassy NE wind at 5 km/h, energy at 891. Very good conditions.

Monday the 31st morning brings 4 ft SW swell with 13-second period, offshore ENE wind at 5 km/h, energy at 516. Clean and fun, but not as big as the weekend.

Tuesday 1 September morning is 3 ft from the SW, 13-second period, glassy ENE wind at 5 km/h, energy at 477. Good, but tame.

Now, another standout appears on Wednesday morning, 2 September. Swell is 2 ft from the SW but with a very long 17-second period, glassy NNW wind at 5 km/h, and energy at 531. That long period will create nicely shaped waves with good gaps between sets – perfect for this beach break, though it can make things a bit straight at times. Still, very good conditions.

Thursday morning the 3rd is 3 ft SW at 15 seconds, cross-offshore NNE wind at 10 km/h, energy at 589. Clean again.

Then we get a final standout on Friday morning, 4 September. Swell of 4 ft from the SW with a 17-second period, glassy NW wind at 5 km/h, and energy at 1028 – excellent for experienced surfers. This is a strong, clean session.

Saturday morning the 5th sees 4 ft from the SW at 16 seconds, but with a slight cross-onshore WNW wind at 5 km/h, energy at 899, so it’s a bit less clean.

Overall, the best on offer are Saturday morning 29 August and Friday morning 4 September – both with glassy wind, solid size, and plenty of energy. Get out there.

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.
