The Lowdown
Alright, folks, Rusty here. Let’s break it down.
We’ve got a solid 16-day window for Playa Santa Teresa. The first few days are a bit slow, but the second half of the outlook really fires up. The water is sitting at 87°, which is a couple of degrees warmer than usual for this time of year – that’s a notable anomaly, so you’ll be surfing in a warm bath for sure.
The first real standout doesn’t show until Friday morning, 28 August. That morning is looking glassy with a NNE breeze, a clean 3 ft swell from the SW, and a long period of 19 seconds giving it some serious grunt. The combined energy is moderate but solid at 707. It’s a good one for getting out there early.
Saturday morning, 29 August, is the top pick of the whole period. The swell jumps to 5 ft from the SW, period 16 seconds, and the combined energy is a strong 1190. Winds are light ENE cross-off, making for clean conditions. This is excellent surf for experienced surfers – the size and power are there, and the wind is your friend. A true standout.
Sunday morning, 30 August, is another strong one with 5 ft from the SW, period 14 seconds, and a moderate 911 combined energy. Offshore ENE winds at 10 km/h keep it clean. This is very good, but it’s a risk of thunderstorms, so keep an eye on the sky.
The pattern continues with a solid Monday morning, 31 August – 4 ft, glassy, period 13 seconds, and a moderate 537 energy. Very good and clean.
Then we hit a bit of a lull. Tuesday 1 September and Wednesday 2 September see the swell drop and conditions turn tricky, but Wednesday morning 2 September is a glassy gem with a long period (18 seconds) and 507 combined energy – worth a look if you’re patient.
The real fireworks come back for Friday morning, 4 September. That’s 4 ft from the SW, period 17 seconds, and combined energy of 1200 (strong). Glassy conditions with ESE wind. Excellent for experienced surfers.
But the absolute best of the entire forecast? That’s Saturday morning, 5 September. A clean 6 ft SW swell, 16-second period, and combined energy of 1438 (very strong). Glassy, calm, no wind. This is a morning for the well-trained only – the size is solid, the power is high, and the conditions are pristine. If you’re experienced, this is your day.
After that, the swell holds through Sunday 6 September and Monday 7 September with 4 ft and 4 ft, glassy mornings, and good energy. The final standout is Wednesday morning, 9 September – 3 ft, 18-second period, combined energy 858, and clean cross-off winds from the east. A nice long-period groundswell that’ll wrap in nicely.
Overall, the best of the best is Saturday morning, 5 September. The second pick is Saturday morning, 29 August. Both are for experienced surfers, with big swell, clean conditions, and serious energy.
