The Lowdown
Alright, let’s get into it. Rusty here.
The next couple of days are pretty flat and messy, but don’t walk away just yet. After a slow start, a solid run of groundswell kicks in and there’s some real magic on the cards.
Thursday the 27th is a write-off. Only 1ft of weak, short-period swell and a thunderstorm brewing. Not worth paddling out.
Friday morning the 28th, though, things start to turn. Playa Santa Teresa wakes up with a glassy sea, a light NNE breeze, and a clean 3ft SW groundswell rolling in with a very long 19-second period. The wave energy is strong, reading 716, and the water’s a balmy 87°, running a touch warmer than normal for the time of year. The swell’s a bit small, but with those long lines and zero wind, it’s going to be supremely fun on a log or a fish.
The standout of the whole outlook is Saturday morning the 29th. That’s the one. Playa Santa Teresa gets a clean 5ft SW groundswell, 16-second period, with a glassy north wind. The combined energy is massive at 1105 – you’ll feel the power. It’s in the sweet spot for experienced surfers, not too big, not too small, just excellent. This is the session to circle on the calendar. Afternoon sees it bump to 5ft but the wind swings onshore and the quality drops.
Sunday morning the 30th is another gem. The swell holds at 5ft SW, period drops a touch to 14 seconds, but the wind is completely dead calm – glassy as a mirror. Wave energy is still strong at 966. Perfect for a long, mellow session without the afternoon thunderstorm risk.
There’s a bit of a lull early next week. Monday the 31st and Tuesday the 1st of September see the swell drop back under 4ft, with cross and onshore winds making things choppy. Nothing to rush for.
Wednesday the 2nd and Thursday the 3rd offer brief morning windows of clean, glassy conditions with 2ft to 3ft of that long-period SW groundswell, but it’s small. Fun if you’re desperate, but not a standout.
Then we get another big pulse. Friday morning the 4th of September brings a return to form: a 4ft SW groundswell, 17-second period, glassy conditions with a light SSE breeze. The combined energy jumps to 1235 – that’s proper. Excellent for experienced surfers again.
Saturday the 5th of September morning is the second true standout. Playa Santa Teresa is absolutely cranking: 5ft of pure SW groundswell, 16-second period, and dead calm wind. Swell energy is 1132. It’s the full package – size, power, and a mirror-like surface. If you can only surf one day in this outlook, make it this morning. The afternoons get onshore, so go early.
The second week sees a few more clean morning windows – Sunday the 6th, Monday the 7th, Tuesday the 8th – each offering glassy conditions with solid 4ft to 3ft groundswell. Not as punchy as the peak days, but still very rideable.
Wednesday the 9th of September morning has a clean cross-offshore NNW breeze and 4ft of 18-second groundswell with strong energy at 935. That’s a lovely setup for a long, drawn-out point-style wave.
Thursday the 10th morning brings another excellent session: 5ft SW groundswell, 16-second period, glassy, with massive energy at 1075. A fitting end to the best part of the outlook.
So overall, this is a cracking stretch for Playa Santa Teresa. The highlight is Saturday the 5th of September morning – that’s the one you want. Saturday the 29th of August morning is a close second. Crowds may be a factor on those days – it’s a consistent spot and word will get out. Get in the water early.
Rusty.
