The Lowdown
Alright, Rusty here. Let’s break this down for Playa Santa Teresa.
First few days are looking pretty flat and funky. Saturday the 22nd and Sunday the 23rd are small, messy, and not worth getting wet for – storm risk and onshore breeze killing any chance of clean surf.
Monday the 24th shows a glimmer. Morning brings a 2ft SW groundswell with an 18-second period, light offshore breeze from the NE – clean, small, but rideable on a longboard. Water temp is a balmy 87°, and that’s a full 4° above normal, so you’re swimming in a bathtub.
Tuesday the 25th is a gem of a morning – glassy, 2ft swell on 16 seconds, dead calm. Nothing big, but clean lines.
Wednesday the 26th and Thursday the 27th keep up the small clean morning windows – 2 to 2ft, off to cross-off winds. Fine for a few turns but nothing special.
Now, Friday the 28th afternoon sees things pick up. 3ft SW swell, period pushing 20 seconds, cross-offshore wind from the NW – combined energy hitting (501). Clean, defined lines starting to roll in.
Saturday the 29th morning is the pick of the first week – 4ft of SW groundswell with a 16-second period, cross-offshore breeze from the ENE. Combined energy is strong at (1003). This is excellent for experienced surfers – chest-to-head high, clean, powerful. Afternoon goes a bit onshore, so hit it early.
Sunday the 30th keeps the quality high – glassy morning, 5ft of SW swell on 14 seconds, combined energy at (906). Dead calm, clean, solid waves.
Monday the 31st is another glassy start with 4ft and a 13-second period. Good clean fun.
Early September has a small lull, but Thursday the 3rd morning brings a 2ft swell with a super long 20-second period, cross-offshore north wind. Combined energy is strong at (605). Clean, long-lining waves.
The absolute standout is Saturday September 5th. We’ve got 6ft of SW swell, 16-second period, glassy conditions with a light sea breeze. Combined energy is cranking at (1570) – very strong, powerful, excellent for experienced surfers. This is the day.
Sunday September 6th is still solid – 4ft, glassy, clean.
Overall, the first week is small and clean in the mornings, with a solid run from the 28th to the 31st. The second week has serious size, especially the 5th. Crowds are possible, especially on the best days, so paddle out early.
Rusty out.

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).
