The Lowdown

Alright, let's get into it. This is your local surf outlook for Cox Bay. I'm looking at the next couple of weeks, and honestly, it's a bit of a mixed bag. We've got some real nice windows coming up, but you'll have to pick your moments.

Right now, we're starting on Friday, September 4th, and the first good news is that we've got some surf right away. The overall pattern is a long-period groundswell, mostly from the SSW, with a combined wave energy reading of 446. That's moderate energy, but the wave quality is the story here. The water temp is about average for this time of year, nothing wild to report.

For the best bet in the early part of the outlook, I'm looking at Friday morning, September 4th. Cox Bay is picking up a clean 2ft SSW swell, with a very long period of 19 seconds. The wind is a light cross-offshore from the SSE, so it's going to be clean. This is a beginner-friendly break, and with that kind of period, the waves will have some real shape and power behind them. It’s a good, mellow option.

Moving into the weekend, Saturday morning, September 5th, is also a standout. You've got a slightly bigger 3ft SSW swell, still with a very long period of 18 seconds, and a light cross-offshore breeze from the SE. The energy is solid (525), and the conditions should be very clean. This is a great call for a long session.

Now, Sunday and Monday get a bit messy. The wind swings onshore and the quality drops. We have a bit of a lull in the quality through the middle of the week.

The next real highlight comes on Thursday morning, September 10th. The swell is a bit smaller at 2ft from the SW, but the period is still a very long 17 seconds, and the wind is a clean cross-offshore from the South. The combined energy is up to 564, showing there's some good push. This is another clean, fun morning.

Then, the real standout of the whole outlook is Friday morning, September 11th. We get a 3ft SW swell, with a 17-second period. The wind is glassy, coming from the SSE. The combined energy hits 628, which is a solid moderate-high energy level. This is about as good as it gets for Cox Bay in this forecast. The waves will be clean, well-shaped, and have great power. This is the one to circle on your calendar.

After that, Saturday the 12th holds some clean conditions in the afternoon with a 3ft SW swell and cross-offshore winds, but the energy drops a bit.

Jumping into the second week, things get more interesting again around Monday afternoon, September 14th. The swell shifts to a short-period (7 seconds) 4ft WNW windswell, but the wind is glassy. The energy is moderate (299). It's a different kind of wave, a bit weaker and more crumbly, but it’ll be fun and clean.

The next big one is Tuesday morning, September 15th. We see a 6ft WNW swell, with a short period of 7 seconds. The wind is a clean cross-offshore from the SSE. This is a solid pulse of energy (534), but be aware, at 6ft, it's getting into the territory where it might be too much for beginners. The short period means it'll be a bit walled up and dumpy, better for a more experienced surfer on a bigger board.

Finally, looking way out to Friday and Saturday, September 18th and 19th, the swell drops right back down to a tiny 1ft to 2ft, but the wind is offshore and clean. It's a very long period (21 seconds) swell, so the energy is there (321-335), but the wave height is small. It'll be clean, pretty, and small.

So, overall, Cox Bay has some real gems. The best of the best is Friday morning, September 11th, with the glassy 3ft SW groundswell. The long-range stuff around the 15th is promising, but less certain. For now, get on that September 11th morning session.

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.
