The Lowdown
G'day, Rusty here. Look, I've gotta be straight with you—this 16-day stretch at Surfside Jetty is a tough one. The forecast is a real mixed bag of small, weak swells and onshore winds that just won't quit. There's a gap right at the start with no real surf, then the whole period is littered with 'poor' or 'marginal' conditions. We're looking at a long, flat spell that just doesn't want to give us a proper wave. The water temp is sitting about average for the time of year, so no surprises there.
Let's run through the days. Tuesday the 25th of August kicks off with a tiny 2ft SW groundswell, period a very long 16 seconds, but it's cross-on and the energy is weak (273). Just not worth paddling out. Wednesday the 26th sees a bump to 5ft from the S, period 12 seconds, and the energy is moderate (853), but again, it's cross-on and the surface is chopped up. The rating's a one out of ten. Thursday the 27th drops to 3ft with a 10-second period, still cross-on, still poor. Friday the 28th has a 2ft SSW swell with a very long 19-second period, but the wind is onshore or cross-on, making it messy. The energy is moderate (425) but the conditions are just ugly.
The rest of the first week into the second is more of the same. Saturday the 29th to Monday the 31st of August, we're stuck with 2ft to 3ft SSW swells, periods around 15 seconds, but wind is always on or cross-on. The energy stays weak to moderate (395 to 566). Tuesday the 1st of September is a 2ft day, energy weak (228). Wednesday the 2nd shows a 4ft W swell, but the period is a short, weak 5 seconds and the wind is 12 mph cross-on—more of a kitesurf setup than a paddle session. The rest of the week into September 9th is a flat, choppy mess with tiny swells and onshore winds. The best of a bad lot might be Saturday the 5th of September morning, with a 3ft SSW swell, 16-second period, and a light onshore breeze. The energy is moderate (782) and the rating is a two out of ten—still marginal, but it's the closest we get to something rideable.
Honestly, there's no standout here. Surfside Jetty is inconsistent at the best of times, and this forecast is a blank run. It's a lean period, but that's coastal life—forecasts can change, and it won't stay poor forever.
Rusty.
