The Lowdown
Alright, surf’s been flat and the forecast is looking pretty bleak for the next couple of weeks. We’ve got a real lull on our hands here.
Sebastian Inlet-First Peak (Treasure Coast) is where we’re looking, and honestly, there's nothing on the cards that's going to get the heart racing. The water’s running a bit colder than usual for this time of year, about 82°F with a -3°F anomaly, which is notable but not crazy.
The next 16 days are pretty much a write-off. We start with some small, choppy, cross-onshore slop on Thursday the 6th and Friday the 7th. The swell does pick up a touch on Friday afternoon, with a 5ft east swell showing some moderate energy (525), but the wind is going to be messy and the quality will be marginal at best. It’s just not worth getting excited about. Saturday the 8th is similar, just a bit smaller. After that, it’s a slow, painful fade to nothing.
From Sunday the 9th onward, we’re looking at a long stretch of tiny, weak surf. The energy just drains away, and we’re looking at knee to waist-high dribble. There are some glassy mornings, like on Tuesday the 11th or Wednesday the 12th, but with only 1ft to 2ft of swell, it’s not going to break properly. You’d be fighting for a wave that’s barely a ripple. The period is short and weak, and it just doesn’t have any push. This is a solid stretch of nothing.
There’s a brief uptick in period to 9 seconds around the 14th and 15th, but the swell height is still tiny, 0.7ft to 1ft, so it doesn't matter. It’s flat. Even the clean conditions on the 16th, 17th, and 18th with light cross-off winds are just a tease because there’s no swell to ride. A tiny 2ft NE swell shows up on Friday the 21st, but it’s still just onshore slop from the east-northeast.
Honestly, for the paddle surfer, this is a dead period. The only thing that might be interesting is if the wind starts howling, but the winds aren't even that strong. It just looks like a flat spell. We’ll need a change in the weather pattern to get any juice back in the tank.
Stay patient. It won’t be poor forever.
