The Lowdown
Alright, Rusty here for your local surf outlook. Let’s get into it.
Right off the bat, we’ve got a bit of a wait. Sorry to say, there’s nothing worth paddling out for until Thursday morning, September 10th. We’re sitting through a flat start, but hang tight because it gets pumping.
The best action is definitely at Black Rocks Jetty. This is a reef break that’s very consistent, so even when it’s small, there’s usually something to snag. The water temp is sitting at 75.7°, which is a touch warmer than normal for this time of year—a nice little bonus if you are in a spring suit.
Thursday morning the 10th is where it kicks off. We’ve got a solid 7.2ft swell pushing in from the SSW, with a nice long 14-second period. That’s proper groundswell energy, and the combined energy here is a whopping 2082 (moderate to strong). On top of that, the wind is glassy from the NW. That means clean, lined-up waves. It’s a big one though—over 5ft, so you’ll want some experience under your belt. It’s a standout for the whole run, just for that first session. The crowd situation is “sometimes,” so you might have company, but not a circus.
Thursday afternoon keeps the love coming with 6.6ft from the SSE, still glassy, and even more energy at 2863. Again, expert territory, but it’s clean and punchy.
We get a little breather on Friday morning the 11th, dropping to 3.6ft, still with a 12-second period. The wind goes onshore from the SW though, so it’ll be a bit lumpy. Not the best, but by Friday afternoon, the wind goes glassy again and it cleans right up. Still small at 3.6ft, but clean.
Saturday the 12th looks fun—4.6ft in the morning, glassy, and crystal clear skies. The afternoon is even glassier with 4.3ft. A good day for a longer board and some cruisy turns.
Sunday the 13th is a mixed bag. Morning wind is onshore, but the afternoon glass-off comes through with a 6.2ft SSW swell and a 16-second period—1857 energy. That’s a proper, powerful swell. It’s clean for the afternoon session, but at 6.2ft, you want to be comfortable out there.
Monday the 14th is another split day. Morning glassy with 5.2ft from the SW is a solid option. Afternoon turns messy with a cross-onshore wind from the south at 9 mph, chopping up the 4.9ft swell. That one’s a write-off.
Tuesday the 15th is back to form. Morning is a bit cross-onshore, but the period jumps to an incredible 18 seconds on a 4.6ft SW swell—energy is 1874. That’s a long-period groundswell, and it’ll reel down the reef really well. The afternoon is an absolute beauty: glassy, 5.6ft from the SSW at 17 seconds, energy at 2364. This is a top session for experienced surfers.
Now, Wednesday the 16th is the big one. Morning brings 8.2ft from the SSW with a 15-second period and a massive 3080 energy reading. Winds are glassy. This is a serious swell—only for experts, but epic if you have the skills. The afternoon gets a bit messy with a 12 mph cross-onshore, so get out early.
We roll into Thursday the 17th and Friday the 18th, with lighter swell around 3.3ft to 5.2ft, mostly glassy or clean. Friday morning the 18th is a standout: 3.3ft but with a 20-second period—the longest of the whole run—and glassy. That’s a very long period swell, so the waves will have serious push and shape for the size. The energy is 1036 (moderate), but the quality will be beautiful.
Saturday the 19th and Sunday the 20th stay small—around 3.3ft to 3.6ft, but with clean conditions. Sunday afternoon even gets a 12 mph offshore wind from the NNE for clean, groomed lines. Not huge, but fun for a longboard or fish.
Monday the 21st is small, 2.6ft to 3ft, but clean. Not a standout, but if you’re desperate.
Tuesday the 22nd has a 3.3ft to 3.9ft SW swell with a 16-17 second period. Morning is glassy, so that’s your pick for that day.
Then we hit Wednesday the 23rd: morning glassy, 3.9ft from the
