The Lowdown
Hey folks, Rusty here. Let’s be straight with you—this outlook is a tough one. For the next week or so, 30th Street/Ship Bottom just isn’t showing anything worth getting wet for. We’ve got a long stretch of small, choppy, cross-onshore junk from Friday the 11th through Thursday the 24th. The swell is tiny, mostly under 2ft, with weak combined wave energy (mostly in the 20s and 30s). Winds are messy, and every day is marked as poor surf conditions. There’s a couple of cleaner days on Sunday the 13th and Monday the 14th with offshore winds, but the swell is still negligible.
Then things get interesting. Around Tuesday the 22nd, the combined energy jumps to 208, but it’s still cross-onshore and choppy—not worth it. The real standout arrives on Thursday the 24th. That morning, 30th Street gets a clean 7ft swell from the east with a period of 8 seconds, offshore light winds, and combined energy of 666. That’s moderate to strong energy. The water temperature is 76°F, which is much warmer than usual for this time of year—nearly 5°F warmer than average. That afternoon the swell bumps to 8ft from the east, period 9 seconds, combined energy 914, with clean cross-offshore winds. This is the best on offer, but heads up: at 8ft, it’s getting into expert-only territory.
Friday the 25th keeps it going with a 8ft east swell, period 10-11 seconds, and combined energy over 1400. Winds stay manageable, but the conditions are described as marginal due to tide or setup. Still, this is a strong groundswell window—long period, powerful, and best for a point or reef, but at 30th Street being an exposed beach break, expect it to wall up and close out in places. It’s big and not for beginners.
After that, Saturday the 26th sees the swell drop back to 7ft, but winds turn cross-on again and the quality fades.
So if you’re waiting, hold out for Thursday the 24th and Friday the 25th. That’s your window. Before then, save the gas. Stay patient. This is Rusty, signing off.
