The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s coming up for Cox Bay over the next couple of weeks.

First off, the water temp is sitting around 59°, which is pretty much normal for this time of year – nothing to write home about, but you won’t need a thick steamer just yet.

The next few days are a bit of a write-off, I’m sorry to say. We’ve got some small, weak swell and the wind is either onshore or cross-onshore, making a mess of things. Saturday the 18th through to Tuesday the 22nd morning are a no-go for anything decent. The energy is weak (under 500 in the combined energy department), and the wave comment is either "poor" or "marginal." You’d be better off taking the dog for a walk.

Now, things start to get interesting from Wednesday the 22nd morning. The wind swings cross-offshore, the swell bumps up to 5ft from the WNW, and the period is a solid 9 seconds. That’s a proper groundswell, and with the wind being clean, Cox Bay should be looking good. The combined energy is moderate (545), and the wave comment is "expect very good surf conditions." This is the standout of the week. By Wednesday afternoon, it goes glassy – absolute magic. Thursday the 23rd morning keeps that clean cross-offshore wind, with the swell holding at 6ft, and the energy is up to 618. That’s your best bet for a proper session. These two days are the real winners.

Friday the 24th gets a bit too big for beginners, with 8ft swell, but the onshore wind spoils it. That’s a pass for me.

Then, over the weekend of the 25th and 26th, we get a completely different setup. The swell direction swings to the SSW, and the period goes very long – 24 seconds on Saturday morning. That’s a deep ocean swell, but it’s only 2ft to 3ft. The wind is light and cross-offshore, so the surface will be clean, but with that long period, the waves will be fat and slow at a beach break. It’ll be more interesting for the longer boards, but it’s not the quick, punchy stuff we saw on Wednesday. The energy is moderate to strong (603 to 940), but the quality is a bit of a question mark for a beachie.

The last few days of the month and into August are a mix of onshore wind and small, short-period swell. Nothing to get excited about.

So, to sum it up: Wednesday the 22nd and Thursday the 23rd are your best days. Clean, chest-to-head-high WNW swell, with light winds. That’s where you want to be.

Rusty.

Information about the Cox Bay Surf forecast

The above surf forecast table for Cox Bay provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Cox Bay can be found by selecting the local surf guide option on the grey menu. Our Cox Bay surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Cox Bay) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. 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. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
