The Lowdown
Alright folks, Rusty here. Let’s get into what’s shaping up for Playa Santa Teresa over the next couple of weeks.
Right off the bat, we’ve got some fun, clean conditions to start the period. It kicks off Monday morning the 10th with a small but clean 3ft SW swell, and the water is a warm 86°, sitting a touch warmer than normal. The morning is the move here, with a light NNE breeze, you’ll find some tidy lines with the swell energy sitting at a moderate 319. The afternoon turns cross-onshore though, so it’ll get messy.
Tuesday the 11th is another classic story. Glassy conditions in the morning with that same 3ft SW swell, and the energy is building (387). The waves will have some decent push. Stay out of the water Tuesday afternoon – that strong onshore wind will ruin it.
Wednesday the 12th is also a morning-only show. Clean 2ft swell, glassy winds in the early hours. The afternoon brings a risk of thunderstorms and cross-onshore winds, so you’ll want to be done by lunch. Thursday morning the 13th will be glassy again but the swell drops to 2ft and energy is low at 179 – it’s surfable, just not much to write home about.
Now, here’s the first true standout of the outlook. Friday morning the 14th is the one to circle. We see the swell jump to 4ft out of the SW with a long 18-second period, and combined energy hitting a solid 823. The wind is glassy from the NNE. This is premium Santa Teresa – clean, punchy groundswell that will reel down the beach. The afternoon will be blown out, so get in early.
If Friday is good, Saturday morning the 15th is even better. Swell pushes up to 5ft SW, still with that beautiful long 16-second period. The energy is very strong at 1004. Glassy wind again. This is excellent for experienced surfers – the bigger swell (over 4ft) will have some push, and the long period means the waves will have shape and power, particularly on the points. This is the best session of the entire forecast. Go get it.
After that, Sunday the 16th still has good 4ft swell and glassy conditions in the morning, but it’s a slight step down from Saturday. The following week sees the energy slowly dropping off. Monday the 17th and Tuesday the 18th have some clean windows in the mornings with waist-high swell, but nothing that demands you cancel your plans.
There is a gap of a few days in the middle of the week. Wednesday the 19th morning brings back a bit of life with 4ft SSW swell and a clean ENE breeze, energy at 646 – a solid, sneaky good session. After that, Thursday and Friday mornings from the 20th are small and only surfable.
A second smaller gap follows, but then we look to Sunday the 23rd and Monday the 24th. Both mornings offer clean, glassy or offshore winds with 1-2ft swell, but the period is a very long 18-19 seconds. That’s a groundswell, and while it’s tiny, the energy is moderate (212 and 229) and those long lines will wrap into the beach better than you’d think. It won’t be world-class, but for a sunrise paddle with hardly anyone out, it’ll be worth it.
Crowds are listed as “sometimes” here, and with the quality on Friday and Saturday mornings, you can bet a few locals will be on it.
So, if you take anything away from this: Saturday the 15th morning is the absolute best session of the window. Friday the 14th morning is a very close second. Everything else is for the dawn patrol diehards or the kite boarders when the afternoon wind picks up.
Stay stoked.
