The Lowdown
Alright mates, Rusty here, talking about what’s up for Surfside Jetty.
Truth be told, this 16-day stretch is looking pretty flat and funky for this break. Mostly small, onshore junk with not much to get excited about. Water temp is sitting at 75°F, which is much warmer than normal for this time of year – that’s a weird one.
Right now and through the start of the week, it’s poor. Monday and Tuesday we’ve got tiny 2ft swell from the SSW with cross-on or onshore wind – choppy and messy. Combined wave energy is moderate in the 211 to 242 range, but the wave quality is just no good. Wednesday drops even smaller to 2ft. Hard pass.
Thursday the 3rd of September morning gives us a 4ft swell from the WNW, but it’s short-period at 6 seconds, so it’s weak and crumbly. Wind turns cross-shore, so it looks a bit better. The combined energy is 370 – moderate – but the surf is only marginal. It’s the best of a bad week though.
Here’s the bright spot. Sunday the 6th of September morning. Glassy conditions, light rain, and a 3ft swell from the SSW with a long 15-second period. That’s a proper groundswell – it’ll have good shape and push. Combined energy is moderate at 289, and with glassy wind, it’ll be clean. This is your one true standout. It’s small, but it’ll be the cleanest wave of the run. Crowds are likely though, so get in early.
Monday the 7th morning is similar: glassy with a 2ft, 15-second SSW swell and 301 combined energy. Clean but tiny. Watch out Monday afternoon – swell jumps to 7ft from the WNW but with a 6-second period and onshore wind. That’s just a bumpy mess, better for kiting.
After that, from Tuesday the 8th through to the 15th of September, it’s back to tiny surf. Swell stays between 1ft and 2ft, with long periods between 13 and 17 seconds, but the size is just too small to do anything with. Winds stay onshore or cross-on, and combined energy drops to weak levels, even down to 91 by the 15th. Not worth paddling out.
So, if you want clean waves, aim for Sunday the 6th morning. Otherwise, it’s a quiet, small spell. Keep an eye on it – things can change.
Rusty out.
