The Lowdown
Alright folks, Rusty here, looking over the next sixteen days for our local sandbar spot, Playa de Arrigunaga. I'll be straight with you, it's a bit of a slow start, but there's a real nice pulse building for the end of the month and into September.
Right off the bat, we've got a long stretch of quiet. From today, the 17th of August, right through until the afternoon of the 19th, the surf is just too small and weak to bother with. The water's warm, 75°, which is a couple and a half degrees warmer than usual for this time of year, but the waves are tiny and messy. You'll be seeing more ripples than rideable waves.
Thursday the 20th sees a little life in the ocean. The morning brings a glassy 3ft swell from the NNW, but the energy is still low (235). It's surfable, but honestly, pretty ordinary. The afternoon bumps up a touch to 4ft, but a cross-onshore breeze from the north messes it up.
Friday the 21st and Saturday the 22nd offer similar sized surf around the 3ft to 5ft mark, with the best chance being Saturday morning when we get a clean, cross-offshore breeze from the ENE. Still, it's mostly marginal.
We then hit another quiet patch from Sunday the 23rd through to Wednesday the 27th of August. Wave heights stay below about 3ft, and the winds are all over the place. There's just no energy to get excited about.
Alright, now for the good stuff. The standout window kicks off on Friday the 28th of August. I'm talking about a proper bump. Friday morning at Playa de Arrigunaga, we’ve got a clean 6ft groundswell rolling in from the NW (12-second period), and it's dead calm – glassy conditions. The energy is pumping at 945, and that combination of size and clean conditions is pure joy for an intermediate surfer. This is your best bet of the whole forecast. The afternoon stays solid at 6ft, though a light cross-onshore breeze creeps in.
The fun doesn’t stop there. Monday the 31st of August has a glassy morning with a punchy 6ft swell from the NW. The energy is strong again (611), so get on it.
Now, for the real cherry on top. Looking ahead to Tuesday the 1st of September, we’ve got a serious pulse. The morning delivers an 8ft swell from the NNW with a very long 14-second period. The wave energy is huge (2379), and it's glassy. This is excellent surf, but that size means it's for experienced surfers only. Beginners, sit this one out as it will be too big. That long period groundswell will be looking for a bank to stand up on, and Arrigunaga, being a beach break, might see those lines break a bit straight. Keep that in mind. The afternoon picks up an onshore wind which messes with the quality a bit.
So, to sum it all up: endure the flat spell, enjoy the solid Friday the 28th morning and Monday the 31st morning, and if you're an expert, mark your calendar for Tuesday the 1st of September. That's the one.
Rusty.
