The Lowdown
Alright folks, Rusty here. Let's get into it. We've got a solid run of swell on the way for Cozies and Geeries, a reef and point set-up that's a beginner-friendly spot but has some real grunt lined up.
The water temp is sitting at 65°, which is about average for this time of year, so nothing unusual to worry about there.
We start off with a bit of a slow-burner. Wednesday afternoon is the first on the cards, but it's messy. We've got a solid 10ft swell from the WSW, but a cross-shore wind is chopping it up. The energy is massive though, reading a very strong 4139. It's not the one to get excited about.
The real standout hits on Thursday morning, August 20th. The swell drops slightly to 8ft from the WSW, but the wind goes glassy. Absolutely still. This is where it gets good. This is a solid, long-period groundswell (16 seconds) with strong energy (3594), and it's going to be clean as a whistle. It's big enough to be for experienced surfers only though. Thursday afternoon stays clean with a light cross-offshore, but the morning session is the pick.
Friday the 21st keeps the fun going. Morning has a 7ft WSW swell with a clean cross-off breeze. Energy is still strong at 2120. It’s excellent for experienced surfers. The afternoon gets a bit windier, but still rideable.
We have a lull over the weekend. Saturday and Sunday see the swell dropping with less favorable winds, so a bit of a break in the action.
Monday morning the 24th perks back up. A clean 6ft from the WSW with light offshore winds. This is your session if you missed the Thursday morning bomb. Excellent conditions for the experienced crew.
Tuesday the 25th drops right off. Small, weak waves. Nothing to bother with.
Now, here’s the big one for the long-range watchers. Wednesday morning, August 26th sees a monster. A 10ft, 19-second groundswell from the WSW hits, but it's blown out by a strong onshore wind. The energy is enormous at 6037, but it's a write-off for surfing.
Thursday the 27th recovers well. A 8ft WSW swell gets a fresh offshore wind. Clean and powerful (2398). This is a serious option for the crew.
The end of the month and into September keeps a consistent 7ft to 8ft swell running. Wednesday morning, September 2nd is another standout. A clean 7ft from the west with a light offshore breeze. Excellent conditions for experienced surfers. Energy is solid at 1538.
Then on Thursday morning, September 3rd, we get another strong pulse: 8ft from the west, with a light offshore and strong energy (3218). It’s looking clean and powerful.
So, to sum it up: The absolute best windows are Thursday morning August 20th for that glassy perfection, and Monday morning August 24th for the next clean one. The long-range stuff from August 27th through to September 3rd has a few more clean windows, but keep an eye on the wind as we get closer.
Stay stoked.
