The Lowdown
Right, let's have a look at what's on the cards for the next couple of weeks or so. It's a bit of a slow burner this time around, not gonna lie. For the first few days, the juice just isn't worth the squeeze. We've got a bit of a lull with small, messy swell and onshore winds. It's not until we get into the second week of August that things start looking a whole lot more interesting.
Let's talk specifically about Chadbourne Gulch. It's a pretty exposed spot, and the water here is sitting at about 59° which is a touch warmer than normal for the time of year, so you can leave the 5/4 at home for a bit.
The first real glimmer of anything worthwhile is on Monday, 3rd August. The morning has a solid 10 ft of NW swell, but with a period of 10 seconds, it's packing some serious energy (3032). That's a lot of water moving around and is going to be too big for anyone who isn't charging. The real standout that day is the Monday afternoon. The wind goes glassy, dead calm, and the swell is pumping at 12 ft from the NW with a 10-second period. That's a massive push of energy (3385) and with clean conditions, it's a dream for the crew who can handle it. Honestly, that afternoon is the highlight of the entire run.
After that, we see the swell back off a bit, but the quality picks up. Tuesday, 4th August arvo sees a drop to 6 ft NW, but with that glassy wind and moderate energy (672), it'll be clean and fun on the right board. Then Wednesday, 5th August arvo is more of the same magic: 5 ft NW and glassy again (524).
Thursday, 6th August arvo is another glassy window with 7 ft NW swell (931). Friday, 7th August arvo is the next real standout. 8 ft of NW swell (1395) with glassy conditions. That is proper wave energy and completely clean. That's expert territory but an incredible prospect.
After that, we settle into a more regular pattern of 5 ft to 6 ft NW swell, mostly with cross or onshore winds, so it's not going to be pristine. The very last day, Friday, 14th August arvo, finishes the run nicely with 3 ft of long-period SSW groundswell (15 seconds) and glassy conditions.
So to sum it up: the first week is a write-off. The window from Monday 3rd August afternoon through to Friday 7th August afternoon is where all the magic is. That Monday arvo is the biggest and cleanest, but every one of those afternoons is worth a look if you're experienced.
