The Lowdown
Alright, let’s talk about Playa Santa Teresa.
We’ve got a solid run of surf ahead, nothing epic but plenty of fun windows if you pick your moments. The water is sitting at 87°, which is about 4° warmer than usual for this time of year, so it’s noticeably warmer than normal – you’ll feel that difference as soon as you paddle out.
The first recommendation kicks off early on Tuesday morning, September 8th. The morning is the key. Tuesday morning is glassy, with a light ESE breeze at 3 mph, and the swell is 3 ft from the SW with a period of 13 seconds. The combined energy is moderate at 556, and it’s clean, fun-sized surf. Tuesday afternoon gets messy with a risk of thunderstorms and onshore wind, so don’t bother.
Wednesday morning, September 9th, is another good call. It’s clear, with a light cross-offshore breeze from the E at 6 mph, and the swell holds at 3 ft from the SW, but the period stretches to 16 seconds. That’s a nice groundswell pulse, giving the waves more shape and energy (520). The morning is clean, but the afternoon turns cross-onshore and choppy, so surf early.
Thursday morning, September 10th, is worth getting up for. Glassy conditions with an E breeze at 3 mph, and the swell bumps up to 4 ft from the SW, period 17 seconds. The combined energy climbs to 881 – that’s a noticeable step up in power. The waves will have some punch, and it’s still beginner-friendly at 4 ft, but the long period means it might wall up a bit at the beach. For a point break or reef, it’d be perfect, but here it’s still fun on the right bank.
Friday morning, September 11th, is very similar – glassy, 4 ft SW swell at 16 seconds, energy at 720. Another top morning session. The weekend drops off a bit. Saturday morning, September 12th, is glassy with 3 ft SW swell, but the period drops to 14 seconds, and energy is down to 355. Still surfable, but not a standout.
Sunday morning, September 13th, is glassy again but smaller – 2 ft SW, 13 seconds, energy 209. It’s clean but ordinary. Monday, September 14th, is the smallest and weakest of the run, with 1 ft swell and period 19 seconds – that’s a very long period but tiny waves, so it’s more of a paddle than a session.
The second week has a few bright spots, but they’re less certain. Tuesday morning, September 15th, has a cross-offshore breeze and 2 ft SW swell at 18 seconds, energy 449 – clean but small. Wednesday morning, September 16th, is clean with 3 ft SW swell at 16 seconds, energy 612 – that’s a solid morning. Then on Saturday, September 19th, the morning is glassy with a WNW wind – that’s offshore for this spot – but the swell is only 2 ft, so it’s more of a longboard morning.
The real standout in the whole outlook is Thursday morning, September 10th – glassy, 4 ft SW swell, 17-second period, big energy. It’s the best combo of size, power, and clean conditions. Friday morning, September 11th, is almost as good, just a touch less energy. After that, Wednesday morning, September 16th, in the second week looks promising with 3 ft and clean conditions, but it’s a long-range call so don’t lock it in yet.
Crowds are possible here – it’s a consistent spot and word gets around. The best windows are mid-week mornings when most people are working. The setup is a beach break, so with the longer period swells, expect some closeouts on the wrong tide, but the banks can hold.
