The Lowdown
Alright folks, Rusty here with a long look at the wave prospects ahead. Let’s get into it.
The whole sixteen-day window is a bit of a mixed bag for Cox Bay. There are plenty of days with clean conditions, but the swell energy is pretty inconsistent. We're looking at a lot of small, long-period groundswells that will make for some tidy little waves when the wind plays nice, but nothing that’s going to have the parking lot buzzing. The biggest issue is the lack of real size and power for the most part.
Water temp is sitting around 58°F, and that’s pretty much bang on the money for this time of year – nothing unusual there. For the first week, we’ve got a few windows of opportunity.
The pick of the first week comes on Wednesday afternoon, September 2nd. There’s a clean 5ft swell rolling in from the West with a moderate 10-second period. The combined swell energy is pretty solid (857), and with a light, clean cross-offshore breeze, that’s going to be the best session of this block. With 5ft, it’s still friendly for most competent surfers. A close runner-up is Thursday morning, September 3rd, with a similar 5ft swell from the West, but the wind is straight offshore from the WNW. The setup looks good but the energy is a touch less (735).
After that, things go quiet and small for a solid week. From Friday the 4th through to Tuesday the 10th, we’re dealing with ankle-to-knee-high stuff, mostly under 3ft. The wind is often light and clean or even glassy, so the quality is there for a longboard or a foiling session, but you’ll be scratching for push. There’s a gap of several days there with no real recommendation for a standard shortboard.
Thursday morning, September 10th is a standout for the pure beauty of it. The swell is tiny at 2ft, but it’s a long-period 17-second groundswell from the SW, and the wind is glass. The energy is moderate (543). It’s not going to be big, but it will be absolutely perfect, clean lines. For the patient soul, this is magic. Friday morning, September 11th repeats the formula – 3ft from the SW at 16 seconds and glassy conditions (535 energy). Another gem for the longboard.
The second week brings some proper size, but with some trade-offs. Wednesday afternoon, September 9th sees a 10ft swell from the WNW, but with a short 8-second period and wind from the WNW. That much size with that period will be a messy, closed-out mess at a beach break. That’s looking like a kite session, not a paddle session. Saturday afternoon, September 12th is similar – a big 10ft WNW swell, short period again (8 seconds), and cross-onshore winds. The energy is massive (1186), but the quality will be poor. For experts only, and even then, be prepared for a washing machine.
Tuesday morning, September 15th offers a final little moment of calm with a glassy 3ft WNW swell at 11 seconds. Good for a small, clean wave to round things out.
So, to sum it up: If you want a proper wave with some push but still clean, clear your schedule for Wednesday afternoon, September 2nd. If you’re a glider or love pristine, tiny waves, wait for the glassy mornings of September 10th or September 11th. The big stuff in the second week is too rough.
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.
