The Lowdown
Alright, Rusty here. Let’s have a look at what’s cookin’ at 30th Street/Ship Bottom.
Overall, this is a grim stretch for the next two and a half weeks. We’ve got a massive gap at the start, with nothing worth paddling out for from now all the way until the morning of August 17th. That’s a flat spell that’ll test your patience. The water temp on the 11th was clocking in at 79°, which is a solid 5° warmer than average for this time of year – more like bathwater than ocean.
The first real flicker of hope comes Monday morning, August 17th. We see a small 3ft swell pushing in from the south, but it’s paired with a moderate offshore wind from the WSW. The wave energy is still weak (89), so it’s more of a longboard groaner than a proper session. It’s surfable, but very ordinary. Not a standout, just a taste.
Things stay flat and messy until Sunday, August 23rd. That afternoon, we finally get a true standout moment. Glassy conditions – dead calm wind – with a clean 4ft swell from the SSW. That’s the best wave energy we see in the whole window, reading at 171 (moderate energy). The period is only 6 seconds though, so it’s windswell, not groundswell. Still, for a beach break like this, the glassy surface will make it smooth. It will be small, clean, and user-friendly. This is your one session to circle.
Before that, on Friday morning, August 21st, there’s a brief glassy window with 3ft from the ENE but the energy is a weak 43 – not really worth racing for unless you’re desperate for a paddle.
Crowds at 30th Street are listed as *sometimes*, so on that Sunday afternoon you might have a handful of others sharing the peaks, but it won’t be a circus.
Everything else in this 16-day window is blown out, tiny, or cross-onshore. No other breaks are in the mix, so we’re stuck with this one spot. If you’re a kite surfer, those windy, choppy days around the 15th and 16th might look more appealing than a surfboard.
Stay patient. The 23rd is your day.
