The Lowdown

Alright, let’s break it down from here.

Right off the bat, I’ve gotta be straight with you—Sebastian Inlet-Third Peak is looking pretty quiet for the next week or so. We’ve got a long stretch where the surf is just too weak and the conditions aren’t doing us any favours. There’s a real gap here from now right through the end of next week where there’s really nothing worth paddling out for. The swell is tiny, mostly around 1 ft to 3 ft, and the wind is a mess—cross, cross-on, and onshore for most of it. We do see a little pulse on Wednesday 16th morning with 2 ft from ENE, but the period is a short 5 seconds and the wind is cross-on, so it’s choppy and weak.

You’re going to be waiting until the 20th of September for anything that looks like real surf. Around Sunday 20th afternoon, the swell picks up slightly to 4 ft from NE with a 10-second period, and the combined energy hits moderate at 223. But the wind is cross-on from the east at 18 mph, so it’s going to be lumpy and tough. It’s still listed as poor surf conditions.

By Monday 21st, we’ve got a similar story: 4 ft from NE morning and afternoon, periods around 9 seconds, energy climbing to 291 and 302. Those are moderate numbers, but that wind stays fresh cross-on from the east at 18 mph, making it lumpy. Not the kind of day you get excited about.

Then on Wednesday 23rd, we see the biggest swell of the whole run: 8 ft in the morning from ESE with 7 seconds, and 10 ft in the afternoon from ESE with 8 seconds. Energy is strong—651 and 950. That’s solid wave height, but the period is short and the wind is cross-on or onshore, so it’s going to be messy and choppy. For a jetty setup like Third Peak, that could appeal to experienced surfers on the bigger swell, but the conditions just aren’t clean.

There is no real standout here. The only window that might get a look is if you’re an expert and you’re willing to deal with lumpy, wind-affected surf on the 21st or 23rd. But honestly, if you’ve got a kite, that Wednesday 23rd with 10 ft and strong onshore wind might be way more fun kite surfing than paddle surfing.

Water temps are sitting around 83°F, which is pretty average for this time of year here, so no complaints there.

So the long story short: there’s a solid gap of poor surf right through until the 20th, and even then, nothing really cleans up. Keep an eye on the forecasts though—it can change quick around here.
