The Lowdown
Alright, this is Rusty comin' at ya.
Alright, look, I gotta be straight with you. The next couple of weeks are looking pretty bleak for your local selections. The whole 16-day window is a tough one, no way around it. We've got a solid run of nothing but marginal to poor conditions, with a massive gap in any real quality surf. Don't get your hopes up for a quick fix; this is a long stretch of flat to weak, messy surf.
The only real window of anything surfable is right at the very beginning, starting Tuesday, July 28th. The best of a bad bunch is Trestles (Lowers). It's a beach and reef setup that's very consistent, exposed to the south-west swell, and it's always got a crowd. The water temp is about average for July, so no nasty surprises there.
On Tuesday the 28th, we've got some swell coming in from the SSW at 4ft, but it's got a long 17-second period. That's a proper groundswell, which means better shaped waves and more energy, but it can make things a little weird at a beach break. The combined energy of all swells directed here is moderate (1064). The problem is the wind. It's a cross-on shoredy from the SSW at 15 km/h, making things fairly choppy. Tuesday afternoon’s a little better with the wind dropping to 10 km/h, but it's still onshore. The tide could be a factor too, so it's not gonna be easy.
Wednesday the 29th is much the same story. Swell drops to 4ft from the SSW, still a long period. The wind is still a cross-on mess in the morning, and the scores are just as low. It’s surfable, but you’ll be working for every wave.
Then from Thursday the 30th onwards, it just falls apart. The swell drops under 3ft, the period drops to 13 seconds, and the energy fades away. The wave comment says it all: "poor surf conditions." We're looking at days and days of weak, choppy, and marginal surf. From Friday, July 31st, through to the end of the forecast on Wednesday, August 12th, there's nothing worth paddling out for. It’s a flat spell with hardly any energy.
So, between the lack of size and the constant onshore or cross-onshore wind, this is a real dud of a forecast. Kite surfers might get a look in with the cross-onshore wind and small waves, but for a paddle surfer? It's a tough watch. The forecast can always change, but for now, it's looking like a couple of weeks of rest.
Rusty.
