The Lowdown
Alright folks, Rusty here. Let’s be straight with you – the outlook for Surfside Jetty over the next 16 days is a tough one to swallow. We’re looking at a long dry spell right through to mid-September, with no real surf to speak of. The first glimmer of anything that might be considered rideable won’t pop up until Wednesday, September 16th, and even then, it’s only a marginal call.
The pattern is pretty grim. Through the first week, we’ve got tiny, weak energy from the southwest, with a lot of cross-onshore wind messing up the surface. The combined wave energy is mostly in the low hundreds (272 to 154), which is weak. The water is a balmy 72° – that’s much warmer than normal for this time of year, a solid 5° above the average, which is notable.
The best you’re going to get in this entire window is a tiny window around Wednesday, September 16th and Saturday, September 19th. On Wednesday 16th, we get a 2ft SSW groundswell (period 18s) with a light offshore wind from the SW in the morning. That’s clean, but it’s still marginal. The energy is weak (276). Then again on Saturday 19th, the morning shows a 2ft SW swell from an even longer period (18s) with a light offshore wind again. The combined energy is a bit better at 391. This is the best on offer, but it’s still small. A long-period swell like this at a jetty can be a bit tricky – it tends to suck the water out and make things shifty. It’s an advanced wave, and it’s *inconsistent*, so you’ll be waiting. Crowds are likely here, as it’s often busy.
We go another week with nothing but poor surf conditions and marginal tide issues. The swell picks up a tiny bit around September 20th and 21st, with 3ft SW swell and moderate energy (up to 459), but the wind switches to cross-onshore or onshore, ruining the clean lines. For a beach-and-jetty setup like this, those onshore days with a bit of size are honestly more interesting for the kite surfers than us paddle guys.
Bottom line: There’s no standout day. The absolute best shot is a dawn patrol on Saturday, September 19th – light offshore, 2ft of long-period SW swell, and a chance of a clean little wave. But it’s marginal, inconsistent, and for advanced crew only. The rest of the period is a write-off.
Rusty.

Further information to help with frequently asked questions about our surf forecast for Surfside Jetty may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself.
