The Lowdown
Alright, Rusty here, givin' ya the lowdown in feet and Fahrenheit.
The water's sittin' around 57°, which is about normal for the season. Nothin' crazy.
The first real chance to get wet is Friday morning, August 21st. We've got a clean 5ft swell from the southwest, with a short 8-second period. A light cross-offshore breeze is keepin' the surface glassy. The combined energy is moderate. By the afternoon, it bumps up to 6ft, still lookin' real good. This is a solid start, but the gem is comin' up.
Saturday morning, August 22nd, is your best bet for the first week. You've got a clean 5ft swell from the southwest, but the period jumps to 10 seconds, givin' the waves some real shape and punch. The combined energy is solid, and with a light cross-offshore breeze, it's gonna be a fun mornin'. This spot, La Boca Con Con, is very consistent, so there's waves for everyone. Just know that crowds can show up sometimes.
Sunday through Tuesday are pretty flat and ugly with onshore winds. Monday morning, August 24th, has a glassy 2ft swell from the south-southwest with a real long 13-second period, but it's just too small. The energy is weak.
The next real standout is Wednesday, August 26th. The morning session has a 5ft southwesterly swell with a 12-second period and a clean offshore wind. The energy is solid. But the afternoon is the one: a 6ft swell from the west-southwest, same long period, with a glassy cross-offshore breeze. The energy jumps up, and the conditions are "very good." This is a top-tier session.
Thursday, August 27th, gets big. The swell hits 8ft in the morning and 10ft in the afternoon with a super long 16-second period. The energy is massive. This is expert-only territory. The wind is onshore, so it's gonna be a messy, powerful beast. This is more of a kite-surfing day than a paddle-surfing day.
The rest of the forecast into the first week of September is a mix of big, lumpy swells. The 4th of September has a 8ft swell from the southwest with a 15-second period, but the wind is strong and cross-offshore, keepin' it clean. The energy is huge, but it's still a big, powerful swell for the experienced.
The last one to watch is the morning of the 5th of September. A 10ft SW swell with a 15-second period and a light cross-shore wind. The energy is massive. Again, big and gnarly.
So, for the best of the best, lock in Wednesday afternoon, August 26th, for the cleanest conditions and a solid, long-period swell. The Saturday morning, August 22nd, is a close second for a more relaxed, fun session.
This is Rusty, out.
