The Lowdown
Alright folks, let’s get into it. It’s been a tough stretch down here, and the next week and a half is going to be a proper test of your patience. We’ve got a long run of small, grovelly waves with a lot of chop on top. The swell is coming from the east, but it’s short-period and weak, and most of the time the wind is just onshore enough to ruin it.
There are a couple of tiny windows, like Friday the 11th when the wind goes light and offshore, but with waves around 1.3 feet, it's barely a ripple. The energy readings are weak, mostly in the 20-40 range, so it's a real flat spell. This is a solid 10-day stretch of nothing worth paddling out for.
Now, here's the light at the end of the tunnel: Monday the 21st. The swell finally arrives from the northeast, pushing into the chest-to-head-high range. The energy jumps to 401 and then to 617 by the afternoon, with the period stretching out to 10-11 seconds. It's not clean, with an onshore breeze, but it's the first real surf we’ll have seen in a long time.
The swell hangs around and builds through the 23rd and 24th, with waves in the 5.9 to 6.2-foot range. The energy readings are massive, in the four-figure range, so there's serious power to it. The wind shifts more to the southeast, giving us a cross-offshore angle on the 24th, which should clean things up nicely. That Thursday morning the 24th at Sebastian Inlet-Third Peak is looking like the standout of the whole period. It's not a beginner wave at that size, but it’s the one you want to be out for.
Otherwise, just wait it out. The water is running about 83 degrees, which is normal for this time of year. Be patient, keep the board close, and be ready for that Monday.
