The Lowdown
Alright, this is Rusty comin' at ya from the beach. Let's get into it, 'cause honestly, it's been a bit of a quiet stretch here.
Alright, listen up. For the next couple of weeks, we're looking at a pretty flat and slow period overall. There are no real standout surf days, and nothing that's gonna get your heart racing. There's a lot of small, weak swell and a lot of days with clean-ish conditions, but the waves just aren't there. We've got a solid gap of poor surf from now all the way through to the end of August, with nothing worth paddling out for. The energy is just too low.
The only glimmer comes right at the very end of the run, on the morning of the 1st of September. That's about a week and a half away, so it's a long-range whisper, but it's the only thing on the board. Walton Rocks (Power Plant) is our only spot, and it's a beach and reef setup that's pretty consistent. The water temp is around 86°, which is about normal for this time of year.
On the morning of September 1st, we've got a tiny 1 ft swell from the east, with a period pushing 13 seconds. That's a long-period groundswell, which means more energy than the size suggests, but it'll be prone to breaking straight on a beach break. The combined energy is a weak 50, so it's barely a pulse. The real highlight is the wind: it's glassy. Dead calm. That's a major positive. The swell direction is a bit off from the optimum (NE), but for a morning with zero wind, it could be just about rideable for a longboard or a foiler. The wind state is described as "surfable waves but very ordinary conditions," so keep expectations in check. It's a tiny, clean, weak wave for the dedicated surfer.
Other than that one morning, the rest of the 16 days is a write-off. The wind is often cross or onshore, and the swell just doesn't get above 2 ft for most of the period. There's a bit of a bump in energy on the 2nd and 3rd of September with slightly bigger swell, but the wind is directly onshore, making it a messy, choppy mess. This setup looks more interesting for kite surfing than paddle surfing.
So, there you have it. One glassy morning in early September is the only thing worth circling on the calendar. The rest is a waiting game.
Rusty.
