Oyster Bay Surf Forecast and Surf Report

Alright, this is Rusty. Let’s talk about Oyster Bay.

It's a sandbar set-up, open to the swell, but for the first chunk of this 16-day stretch, it’s a whole lot of nothing good. We’re looking at a rough patch of poor surf with messy winds and chop that will test your patience more than your skill. The water is much colder than average for this time of year, sitting around 62°, which is well over 3 degrees below normal, so dress warm.

Friday the 28th kicks off with a 4ft southerly swell, but a nasty 30 km/h cross-wind has it ruined. Combined wave energy is moderate at 997, but the quality is junk. Saturday is just as grim with stronger onshore winds and dropping swell. Sunday morning stays average with 6ft, but by Sunday afternoon we finally get a bit of a pulse with a 8ft swell from the southwest, period stretching to 12 seconds, and a light breeze coming onshore. The energy jumps to strong at 1577, and conditions get a "marginal" nod, meaning it might be rideable if you're keen and the tide plays ball, but don't expect perfection.

The one true standout window lands on Tuesday morning, September 1st. The wind goes glassy—dead calm—and that’s a massive positive. You’re looking at a clean 7ft southwest swell with a solid 11-second period, and energy is strong at 1101. This is the best on offer for experienced surfers. It’s not huge, but it’s clean, and that makes all the difference. The afternoon gets wrecked by a fresh cross-onshore breeze, so get on it early.

After that, things get wild, and not in a good way for paddling. September 2nd and 3rd see the swell pumping up to 13ft and beyond, with periods hitting 18 seconds. That’s a very long period groundswell. The energy is enormous, hitting 10638, but the break’s notes say it's simply too big for this spot. For a sandbar with this much power and size, you’d need a boat and a tow rope—this is kite-surfing territory, not paddle surfing. The same goes for September 4th through the 6th, with 13ft to 18ft swells and howling winds that keep the water clean but the size well out of the comfort zone for any typical surfer here.

The second week drops off significantly. From September 7th, the swell backs right down to under 3ft, and the energy sits weak at 473 to 415. Winds are onshore and choppy most days, offering nothing worth chasing. There’s a flicker of hope on Friday the 11th: a clean 8ft easterly swell with light offshore winds, moderate energy at 909, and the report says "very good surf conditions." That morning is worth a look. Saturday the 12th follows with a similar story—5ft easterly swell, gentle offshore, and glassy conditions by afternoon. Those two days are the second-week highlights, but remember, it's a long-range call so treat it as promising but not locked in.

Overall, your best bet is Tuesday morning September 1st, with the glassy clean 7ft southwest swell. Second pick goes to that Friday the 11th dawn session. The rest is a write-off for paddling, with a big gap of dangerous, oversized swell in between.
