The Lowdown

Alright folks, this is Rusty. Let’s have a look at what’s on offer for Cox Bay over the next couple of weeks.

Right off the bat, it's a slow start. The first few days are pretty much write-offs, with weak, small swell and onshore winds messing things up. The water temp is sitting at 60°F, which is pretty normal for this time of year, so no surprises there.

The first real glimmer of hope comes on Thursday morning, the 13th of August. We’ve got a clean 4ft swell from the W with a short 7-second period, but the key is the light cross-offshore breeze from the SSE. That should keep the faces tidy. It’s not a monster, but it's the first decent opportunity.

Hold on, though, because the real standout window is shaping up for Saturday afternoon, the 15th of August. That’s the one to circle on the calendar. We’re looking at a 2ft swell from the SSW with a solid 18-second period, giving it some real long-period groundswell energy (543). The kicker? The wind is forecast to be glassy. That’s right, completely flat water. Cox Bay will be clean and peeling, with long, waiting sets. For a beach and point setup, that long period might make it break a bit straight in sections, but the glassy conditions will make it an absolute dream for logging or a longboard. This is the best on offer, hands down.

After that, things get a bit mixed. Sunday morning the 16th sees a little bump in size at 3ft, but the wind goes cross-onshore, making it messier. The energy stays moderate (462) but the quality drops. Through the rest of the week into the 20th, we see a few mornings with light cross-offshore or cross winds and some waist-high, short-period swell, but nothing that really screams "go-time." The conditions are often marginal.

Into the second week, from the 21st onwards, the pattern gets more consistent but worse for quality. The wind parks itself in the WNW, blowing onshore or cross-onshore pretty much constantly. The swell sticks around in the 2ft to 4ft range, but with onshore wind and short periods, it’s going to be a choppy, messy close-out. The energy is moderate (around 390-443), but it’s just not surfable in a good way. Honestly, for the last week of the forecast, you’d be better off looking at kite surfing than paddle surfing if the wind stays that strong.

So, to sum it up: the first week has a couple of windows, with Saturday afternoon the 15th being the absolute standout. The second week looks like a dud. Keep an eye on the forecasts, but don't hold your breath.

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.
