The Lowdown

Alright folks, Rusty here. Let’s look at what’s on the table for Cox Bay. We’ve got a bit of a slow and patchy run ahead, but there are a couple of windows of clean, long-period swell that are worth marking in your calendar.

We start off with a bit of a dud. Tuesday the 8th and Wednesday the 9th are pretty flat or messy with onshore winds, so don’t bother paddling out. The swell is small, the energy is weak (291-416), and the conditions are all wrong.

Thursday the 10th sees a bump in size, but it’s a short-period, choppy mess. By Thursday afternoon we’re looking at 8ft swell from the WNW, but it’s lumpy and cross-onshore. That’s more of a kite-surfing day than a clean paddle session. The energy is picking up (982), but the quality is poor.

Now, Friday the 11th, that’s where the magic starts. We’ve got clean, offshore winds from the East, and a beautiful 3ft groundswell from the SW, with a very long period of 17 seconds. That’s proper, powerful energy (613). The water temp is about 58°F, which is normal for this time of year. This is a standout for the clean, lined-up waves, especially for the more experienced crew. The long period might make it a bit straight at the beach, but it’ll be gorgeous on the point. Expect clean conditions with that offshore breath.

Saturday the 12th morning is another gem. Glassy conditions, a light 3ft SW swell with a 15-second period, and moderate energy (526). This is the best of the first week. The wind is dead calm, the water is slick, and the sets will have some punch. Beginners will find this manageable, but the long period means it’s best over the reef or point.

After that, the surf drops off again. From Sunday the 13th through to the morning of the 18th, we’re looking at small, weak swells (1ft to 2ft) with mixed winds. There are a few clean windows with cross-off winds, but the size is too small to get excited about. The energy is low (187-429). It’s a long gap of underwhelming surf.

Then, on Friday the 18th morning, we get a glassy start with a tiny 1ft swell, but a very long period of 21 seconds. That’s a whisper of energy (375), but for the expert on a log, it could be a fun, clean session. Not a standout for the masses.

The real standout of the second week lands on Saturday the 19th morning. Dead calm, glassy conditions, and a 2ft SW swell with a 19-second period. The energy is moderate (392). This is a rare, flat-calm, long-period groundswell that will be perfect for the point. The light rain might keep the crowds away, which is a bonus.

Sunday the 20th morning is also worth a mention—glassy with a 2ft, 18-second SW swell (473 energy). That’s another clean window.

The final potential is Tuesday the 22nd, but it’s a big, raw swell. We’re looking at 6ft to 6ft from the W, with a 12-second period and very strong energy (1262-1294). This is expert territory. The wind is onshore, so it’ll be a messy, powerful beast. Not for the faint of heart.

Bottom line: Friday the 11th and Saturday the 12th are your best bets for clean, quality waves. The second week’s standouts are the glassy mornings of the 19th and 20th, with long-period groundswells, but they’re small. The big stuff on the 22nd is for the hardcore crew only.

Stay stoked, and keep your eyes on the horizon.

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.
