The Lowdown
Alright, Rusty here with the imperial version. Let’s cut to it.
The big news is a serious run of west groundswell, and the one to circle on your calendar is Friday morning.
Monday morning we’re looking at a clean 5ft swell out of the WSW with a long 15-second period, light cross-off breeze, and water temp sitting at 54°F – right about average for the time of year. The energy reading is 1203, which is solid. It’s a powerful, consistent swell but the wave comment flags it for experienced surfers only. Monday afternoon gets cross-on and a bit sloppy, so morning is where it’s at. Tuesday goes glassy with a 4ft swell – clean but small.
The gem of the whole forecast is Friday, September 18th, morning. We’ve got a 5ft WSW swell, 15-second period, combined energy of 2309, and light cross-off breeze from the south. That’s about as clean as it gets for an exposed channel break like Cobden Beach - The Channel. The swell direction is right on the money. Crowds are rare here, so you’re looking at quality waves without a crowd. Friday afternoon jumps to 8ft but the wind turns and it gets too big for the spot.
Saturday through Tuesday is all oversized west swell – 8ft to 13ft – but the wind is either cross-on or messy, and the advice is it’s too big or poor. That’s a stretch of days for the big wave crew only, and even then it’s not clean. Wednesday the 23rd still has 12ft swell but clean in the morning with a light offshore – again, expert territory.
Thursday the 24th gives us another morning window: 6ft WSW swell at 14 seconds, light cross-off, clean, and excellent for experienced surfers. After that, the wind goes onshore and the quality fades through the weekend.
So here’s the takeaway: Friday the 18th morning is your standout. Thursday the 24th morning is a solid backup. Don’t sleep on the good windows. The rest is either too big, too messy, or too small.
Rusty, out.
