The Lowdown
Alright, this is Rusty, and I’m gonna give it to you straight about what’s cooking at Strathmere.
Honestly, mate, for the next couple of weeks, we’re looking at a real flat spell. The first week and a half is pretty much a write-off, with nothing but tiny, weak, and often messy conditions. The surf just isn’t there for a proper paddle. We’ve got a long stretch from the 29th of August all the way through until the 9th of September where the wave energy is mostly in the teens, twenties, and low hundreds. The combined energy barely tops 102 (moderate) for a brief moment on the 2nd of September, but that comes with rain and a choppy, cross-onshore wind. Not worth the drive.
There’s a real glimmer of hope, though, if you’re willing to wait. The standout session looks to be on Saturday the 12th of September. Sumner Avenue (Strathmere) is a beach/jetty setup, and it’s exposed to the swell. For the morning, we’re looking at a glassy, clean surface with a 4ft swell from the ENE. The combined energy hits 93, which is still weak to moderate, but it’s the most surfable we’ve seen. The afternoon cleans up a bit more with a cross-off breeze and a 4ft swell from the same direction, bumping the energy up to 119. The swell period is short, at 6 seconds, so it’ll be a bit crumbly, but for a flat spell, this is the best on offer. The water temp is going to feel much warmer than normal for this time of year, which is a nice bonus.
The few days before that, like the 10th and 11th, have a couple of "surfable but ordinary" moments, but the swell is tiny (1ft to 2ft) and the energy is weak. It’s not worth getting excited about.
So, to sum it up: the first week is a dud. The second week offers a single, promising window on the 12th of September. After that, it fades back into small, cross-shore mush. Keep your eyes on that Saturday, because that’s as good as it gets for now.
Rusty.
