The Lowdown
Alright, let’s talk about it.
The first real window of quality surf shows up early on, with the standout being Wednesday morning. We’ve got a solid SSW groundswell pushing through at 13ft, with a 17-second period. That’s a proper pulse of energy, and the wind is dead calm, glassy. It doesn’t get much cleaner than that. The combined wave energy is strong, reading 8708, so there’s plenty of push. This is a big one, so if you’re not advanced, sit this one out.
The water’s running a touch warmer than usual for this time of year, about 3°F above the norm, so it’s 76°. Not a game-changer, but you’ll notice it.
That Wednesday morning is the pick of the whole run. The afternoon before it, Tuesday, is building up with 12ft SSW and cross-shore winds, but the morning is where it’s at.
After that, the swell backs off a bit. Thursday still has some clean 7ft waves with light winds, but the energy drops into the moderate range. Friday and the weekend settle down to 4ft to 5ft, fun for the log but nothing special. There’s a bit of a lull in the middle, with a few days of smaller, weaker surf, but the consistency stays okay.
Now, looking further out, the second week gets interesting again. Around the 18th, we see another long-period SW groundswell building, with a 21-second period on Friday morning. It’s still a bit far off, so don’t book your flights yet, but the potential is there for another good run. The swell size is around 7ft, and with that very long period, this reef setup should handle it beautifully, as it’s exposed to the SW.
Keep an eye on that. The week after that seems to settle back down to smaller, cleaner waves, nothing that’s going to get your heart racing.
So, to sum it up: Wednesday morning is the standout. Get it while it’s good. The following week has a promising pulse around the 18th, but that’s a “wait and see” situation. The rest is mostly smaller, clean surf for the longboard or funboard. This spot is very consistent, so there’s always something to ride.
Rusty out.
