The Lowdown

Alright, let’s break it down in feet and miles per hour.

Honestly, the next week and a half is a total washout. From Monday the 24th through to Saturday the 5th of September, the wind is a relentless cross-onshore from the ENE, blowing 20 to 25 mph. The surf is there, from 4 to 7 feet, but it’s all blown out, lumpy, and messy. For a spot that needs a clean north-northeast swell, this wind direction is a nightmare. The combined wave energy is moderate to strong, but it’s all for nothing. That’s a solid two-week stretch of nothing worth paddling for.

But, there’s a light at the end of the tunnel. Sunday the 6th of September morning shows a glimmer of hope. The wind drops to a fresh cross-shore breeze, and we’ve got a 6-7 foot swell with a 12-second period. That’s a long period groundswell with a ton of energy (1262). It’s listed as marginal, which is a big step up from the rest. The cross-shore wind will still leave some bump, but it’s the best we’ve seen.

Monday the 7th of September is your best bet. The wind eases to a moderate 12 mph cross-onshore, and the swell holds at 7 feet from the NE, with an 11-second period. The energy is still strong (1009-1069), and it’s again rated as marginal. It’s not glassy, but it’s clean enough to score a few. For a spot that’s fairly consistent and sometimes crowded, you might have some company.

The standout is the morning of Monday the 7th of September. The swell is a solid 7 feet from the NE, and with a moderate cross-onshore breeze, it’s the cleanest window in the whole forecast. It’s still a bit lumpy, but it’s the only time the wind isn’t howling. For the intermediate surfer, that 7-foot day is a good challenge, but it’s not for the faint of heart.

That long period swell on the 6th is a tease, but at a beach break, that 12-second period can make things a bit fat and closed out. Still, it’s a promising finish to a grim start.
