The Lowdown
Right now, Walton Rocks (Power Plant) is looking pretty grim, folks. We’ve got a run of nothing but poor surf conditions stretching out for days, so don’t get your hopes up for any real waves just yet.
The first week of this forecast window is a total washout. From the 16th through the 25th, every session is rated as poor. We’re looking at tiny, weak swells – most of the time under 3ft – with short, choppy periods. The wind is mostly cross-onshore or onshore, which is just adding to the mess. There’s a lot of storm risk around too, which doesn’t help. The wave energy is weak, mostly in the double digits or low hundreds. It’s just a flat, bumpy mess.
Then, things start to get a little more interesting. On the 27th, the swell picks up, but it’s still being hit by that cross-onshore wind. By the 28th, we’ve got some serious size, but the quality is still poor. We’re talking 10ft to 11ft of cross-onshore, choppy chaos. That’s too big and messy for most of us. The energy is strong, around 1941 to 2595, but it’s not doing us any favors.
The only slightly better window is the 29th and the morning of the 30th. It’s still marginal, but the swell is coming down. On the 29th, we’re looking at 8ft to 10ft, and the wind is a bit lighter. Still cross-on, but it’s a little more manageable. The 30th morning has a 6ft swell with light winds, which is the closest thing to a clean-ish wave, but it’s still onshore.
So, for the next week, this place is a no-go. Honestly, from the 16th to the 27th, you’d be better off finding something else to do. Once that bigger swell arrives around the 28th, it’s just too big and blown out for any reasonable paddle session. We might see a window of opportunity on the 29th and 30th if the wind eases up, but with the outer-swell direction coming from the ENE, it’s not going to be pretty.
If you’re an expert and the 29th looks like it’s cleaning up, it could be a grinder, but for the average surfer, I’d file this one under "wait for a better forecast."
