The Lowdown

Alright folks, Rusty here. Let's be straight up about what's happening over the next couple of weeks. I've got the data in front of me, and for the local spots, we're looking at a pretty barren run. There’s a long stretch of nothing before we get to one specific day that might just make it worth hanging in there.

The whole 16-day window is dominated by a lot of tiny, weak swell mixed with unfriendly onshore winds. From now through to the end of next week, it's pretty much a no-go. You'll be staring at a flat, choppy lake. That friendly southeast offshore we usually love? It shows up now and then, but the swell just isn't there to back it up. The combined wave energy barely reaches double digits most days – you'd be looking at numbers like 5 or 14 (weak wave energy), which is basically no power at all.

There's a bit of a tease around Sunday the 13th of September on the morning. We see the combined swell energy jump to 116 (moderate), a jump from the nothing we've seen. But the problem is the wind. It's a cross-onshore from the WSW at 12 mph, just mucking up what little potential that 1 ft swell from the WSW has. The period is a very long 17 seconds, which usually means nice lines, but they'll be wind-chopped to hell. It's not our day.

Now, if you're a patient surfer, your window is Tuesday, September 15th. This is the only true standout. The morning brings a fresh 19 mph offshore from the southeast. That's clean, clean conditions. The swell is tiny, just 2 ft from the SW, with a period of only 5 seconds, so it won't have any real push, but that offshore wind will make it glassy. The afternoon is the best of the whole outlook: light winds from the south at 9 mph, creating clean conditions with a little side-offshore angle. For a spot that rarely breaks like Gantheaume Point, even this tiny 1 ft pulse from the WSW is a miracle. If you see any ripple, you jump on it because the stars align for a clean surface. It's not for the crowds (it's "never" crowded anyway), just for the purist who wants a clean slide.

Don't bother with the rest. The second week is even worse, just flat or tiny cross-onshore junk. But that Tuesday morning, and especially that afternoon, is the only little blip of hope on the chart.

The water's sitting at 78°F which is a touch warmer than average for the time of year, so at least you won't freeze while you're waiting for a set that might not come.

Stay patient,
Rusty.
