The Lowdown
Alright, listen up. We’ve got a bit of a dry spell on our hands. The next two days, the 17th and 18th, are not worth your time. The swell is tiny, the winds are all over the shop, and the surf is just poor. You’re better off doing anything else.
Now, the first real glimmer of hope comes on the morning of the 19th. We’ve got a clean 3ft swell coming from the W, with a long 12-second period. The wind is glassy, which is a huge plus. This could be some fun, clean surf at Cox Bay. The energy is moderate, so it’s not a monster, but it should have some push. Because of that long period, the beach breaks might be a bit straight, so look for the points or any sandbars that are doing their thing.
After that, we slip back into mediocrity. The 20th and 21st are small and messy. The 22nd has cleaner conditions, but the swell has dropped right off. The 23rd and 24th are looking pretty flat and poor.
The next one to watch is the afternoon of the 25th. A bump of 4ft from the WNW shows up, and while the period is a bit shorter, it could be a bit of fun. It’s a bit onshore, so it might be lumpy, but there could be something there.
The 26th is similar, but then it all just fades away. From the 27th right through to the end of the month, we’re looking at tiny, weak, and blown-out surf. It’s a real flat spell. The 1st of September shows a faint pulse of life, but it’s still small and the winds aren't great.
So, your standout window is the morning of the 19th. That’s the one to get. The 25th is a possible backup, but it’s a step down in quality. The water is at 59°F, which is about average for the time of year.
It’s gonna be a waiting game, folks. Patience is key.

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.
