The Lowdown
Alright, it’s Rusty here. Let’s be straight with you—this is one of those stretches where the ocean just doesn’t want to play ball. We’re looking at 30th Street/Ship Bottom, and honestly, there’s nothing in the next 16 days that’s worth getting excited about.
The water temperature is sitting at 78°F which is *much warmer than normal* for this time of year by 4°, so if you’re just wanting a swim, it’s lovely. But for surf? The entire forecast is stuffed with poor surf conditions. The wave energy is weak, barely cracking 86 (combined energy of all swells) at the best of times, and most days it’s sitting below 50. The swell is tiny—mostly 0.3 ft to 3 ft—and coming from the SE or E, with a period that’s often short, around 5 to 9 seconds, which means weak, crumbly waves.
We’ve got a real gap here. From now through to the end of the month, there’s not a single session that’s recommended. The wind isn’t kind either—onshore or cross-onshore most of the time, with only a few windows of clean conditions on Monday the 17th and Tuesday the 18th, but even then the swell is just too small to do anything with. On the 24th, the period picks up to 12 seconds, but the swell height is only 0.7 ft to 1.0 ft, so it’s more of a ripple than a ride.
If you’re a beginner, you might find a little knee-high wave on Monday the 17th morning (3 ft, SSE, 6 seconds) with light offshore wind, but it’s not going to be memorable. The 21st through the 23rd sees a bit of a bump in size to 3 ft, but it’s accompanied by light rain, onshore wind, and short period—making it messy and choppy.
This is a tough run. For a spot that’s only fairly consistent at the best of times, a blank forecast like this is more normal than not. Sometimes you just have to wait for the next system. Keep an eye on the sky, because forecasts can change, but right now, there’s no standout—no reason to paddle out.
Rusty, signing off.
