The Lowdown
Alright folks, Rusty here. Let’s get into it for the local stretch.
Honestly, for the next two weeks, it’s a bit of a tough stretch. The forecast is largely a flat spell with very little energy to get excited about. The combined swell energy is weak, often sitting in the low double digits, and the waves are small with poor quality. Don’t expect any real standouts, but there are a couple of windows where the conditions improve enough to get a wet suit on.
The first real chance for a surf comes on Friday, 18th September. The morning looks best, with a bit of a dawn patrol vibe. The swell is still small, only about 3 ft, coming from the ENE with a period of 7 seconds. The wind is coming from the WSW at 12 mph, which is offshore, and that’s a major positive. The water is much warmer than normal for the time of year, sitting at 78°F (that’s a 5°F anomaly), so you won’t need a thick suit. The combined energy is 70 (moderate), but the waves are surfable if you’re not expecting much. There is only one break on offer, 120th Street. It’s a beach/jetty setup, so with the offshore wind, it could be clean and fun for a longboard. Expect crowds to be possible, as it’s a consistent spot.
After that, the next window is on Wednesday, 24th September. The morning has a 4 ft ESE swell with a period of 7 seconds, and a light cross-offshore wind from the NW at 3 mph. The combined energy is 139 (moderate), so there’s a bit more push. The afternoon gets even better: glassy conditions with a 3 ft ESE swell and a period of 7 seconds, with the wind swinging to the WNW at 3 mph. The combined energy is 108 (moderate). Both sessions are surfable, but the afternoon glass-off is the standout. The waves won’t be huge, but clean and glassy at 120th Street is a rare treat. The crowd factor is still possible.
Overall, it’s a waiting game. The first week is a write-off until the 18th, and then a gap until the 24th. Keep an eye on the forecasts, but don’t get your hopes up too high.
Rusty.
