The Lowdown

Alright, let me tell you how things are looking for our stretch of coast. I've been staring at the charts and, honestly, there’s not a whole lot to get excited about. The next couple of weeks are going to be a real waiting game. The swell window is looking pretty quiet, with only small, short-period wind swell from the east showing up. It’s going to be a long stretch of small, weak waves.

Right now, into the start of the 16-day run, we are looking at a big gap. There’s basically nothing worth paddling out for. The water temp here is sitting at 84°F which is about average for this time of year, at least the water is warm for a float.

Sebastian Inlet-Third Peak is the only spot on the cards, but it’s going to be a tough one. For the next week and a half, from Sunday the 16th all the way through to Saturday the 29th of August, we are dealing with tiny surf. The swell is mostly 1.0ft to 2ft from the east, with a weak period of 8 to 9 seconds. The combined wave energy is very weak, barely cracking 10 to 30 in the early part. Winds are a mixed bag. There are some nice, clean, glassy mornings with light offshore breezes from the west-southwest, like on Wednesday the 19th and Saturday the 22nd, but the swell just isn’t there to make it worthwhile. Afternoons tend to get a seabreeze from the east or southeast, which chops things up.

Now, peeking ahead towards the very end of the month and into the start of September, things get a little more interesting, but it’s a long way out. On Thursday the 27th of August, we see a jump in energy. The swell bumps up to 2ft to 2ft from the east, and the period stretches out to 12 seconds. That’s a proper groundswell. The combined energy hits 123 to 148, a noticeable step up in power. It is a long-period swell for a beach/jetty setup, so expect it to be a bit walled and straight, but there will be more push. The downside is the wind is cross-onshore from the east-northeast, so it won’t be perfect, but for that part of the coast, it’s the most surf we’ll have seen in a while.

Friday the 28th looks similar, with 2ft east swell at 10 seconds, but lighter winds. The energy drops a touch but is still moderate.

Honestly, for the first two weeks, you’re better off checking the long-range forecast for the last few days of August. That window around Thursday the 27th and Friday the 28th is the only real standout, but it’s still small and onshore. Don’t expect any magic.
