The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the table for the 16-day window. We've got one spot on the radar, and it's a mixed bag of a forecast.
The overall pattern is one of small, inconsistent waves with a few promising windows of clean conditions. The water is sitting at 60°F, which is about average for this time of year, so nothing unusual there.
For Cox Bay, the first real glimmer of hope comes on Tuesday, 18 August. The morning session is the standout. We're looking at a clean 3ft SSW swell with a 14-second period. The wind is light and cross-offshore, making for some tidy lines. The combined wave energy is moderate, sitting at 527. This is the best on offer for the first week. The afternoon glass off on Tuesday is also a nice little window, with a 2ft SW swell going glassy.
Then Wednesday, 19 August morning keeps the good vibes going with glassy conditions and a 3ft W swell, though the drop in period to 12 seconds means less grunt. It’s still a good option.
The surf gets a bit of a bump in size on Sunday, 23 August morning, with a 4ft W swell, but it's a short-period windswell of only 8 seconds. The good news is the wind is glassy. It’s a clean, fun wave, but it won't have the punch of a proper groundswell.
The real highlight, the one that's worth circling on the calendar, is Sunday, 30 August. The morning session is firing. Expect a very clean 3ft SSW swell, glassy wind, and a beefy 18-second period. The combined wave energy is a solid 673, which is moderate. This is proper groundswell energy, and with that long period, it could be a real treat. The wave quality and the conditions are a one-two punch that makes this the best call of the whole 16-day stretch. Keep an eye on it, as it's a bit further out.
The rest of the time is a lot of nothing or poor conditions. There are long gaps with no real recommendations. From the 24th through the 27th, onshore winds and short-period junk make for a write-off. The 28th and 29th are also messy and not worth paddling out for.
This spot is a beach and point setup, and it's a beginner-friendly spot. Keep in mind that crowds are possible here, so get in early for the best windows.
Rusty.

Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Cox Bay may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself.
