The Lowdown
Alright, let’s talk about what’s coming up. Rusty here, and we’ve got a quiet start with a couple of windows that could be worth the wait.
Right now it’s flat. The swell is barely a ripple at 0.3ft to 1ft, with the combined energy at 11 – basically nothing. The wind is messy, cross or cross-onshore. There’s no surf worth mentioning from now through the end of August and into the first day of September.
Tuesday, 1st September we finally see a change. Early morning at Walton Rocks (Power Plant) turns glassy with a light wind from the WSW. The swell is just 1ft from the East, but it’s got a 15-second period – that’s long-period groundswell. The energy is weak (86), but it’s a clean, rideable wave for a longboard. The water temp is about normal for this time of year.
Wednesday, 2nd September is more of the same early – glassy conditions with 2ft East swell. The period drops to 13 seconds, but the energy climbs to moderate (122). It’s still small, but it’s clean. Afternoons get chopped up again.
Thursday, 3rd September is the clear winner. The morning brings a fresh cross-off wind from the WSW and the swell pushes to 3ft from the East with a solid 14-second period. The combined energy is strong (368). But the real magic is the afternoon: an offshore wind from the SW at 9 mph, with 3ft East swell. It’ll be glassy and fun. This is the day to make a move. With a longer period swell, Walton Rocks – being a beach and reef – will have some good lines, but the sets could stand up a bit straight.
From Friday 4th September through to Tuesday 8th September, it’s back to small stuff (2ft to 2ft). Winds stay mostly offshore or cross-off, so it’s clean, but the energy drops back to weak-to-moderate (49-170). Fine for a longboard or a learner, but nothing to set the world on fire.
So, mark your calendar for the afternoon of Thursday, 3rd September. That’s your best shot. The rest is small and clean, but mostly a waiting game.
