The Lowdown
Alright folks, Rusty here. Let’s have a look at what we’ve got coming down the line for this region over the next couple of weeks. I won’t sugarcoat it – it’s a pretty bleak outlook overall. We’re staring down a massive, frustrating gap where there’s just no quality surf on offer for days on end. We’re not seeing anything that would get a local out of bed for a proper session. The only real glimmer of light is way out there, and it comes with a big question mark.
Walton Rocks (Power Plant) is the only game in town, and it’s a game I wouldn’t be rushing to play. Right out of the gate, starting Tuesday the 15th, we have onshore winds and tiny, weak swell. The combined swell energy is pitiful, barely registering (18) with the swell coming from the east at a shocking 1.0 ft. That’s flat. This theme carries straight through the whole first week and into the next. We see some pickup in size around Thursday the 17th, with the swell hitting 5.2 ft from the NE and the combined energy climbing to 476 (moderate), but the wind is hammering it straight onshore. It’s messy, blown-out, and just not worth paddling out for. For the following days, we are stuck with tiny to small waves, mostly onshore wind, and energy readings that rarely break triple digits. It’s a long, sad stretch for the surfer looking for a slide. Water temps are sitting about average for this time of year, with no major anomaly to note.
Now, about that glimmer. On Wednesday the 30th of September, the forecast throws up a spike of energy. We’re looking at a 6.9 ft swell from the ENE, with a combined energy of 737 (strong). That’s a real pulse of power. But before anyone gets too excited about a reef or point session, the wind is coming from the E at 6 mph, putting it as a light cross-onshore. At that size, 6.9 ft can be a handful, tipping it into the realm for intermediate to advanced surfers. This is a long-range call, so treat it as promising but far from certain.
So where does that leave us? Honestly, this stretch looks more interesting for a kite surfer than a paddle surfer on most days. The combination of onshore wind and clean, straight waves creates a dynamic that’s just not appealing for a traditional surf. Keep an eye on that last day, September 30th, but don’t hold your breath.
