The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ for Cox Bay over the next couple of weeks.
Honestly, we’re in for a bit of a slow start. The first week is pretty flat and sloppy, with weak, short-period leftovers. The real standout window is the second week, from Tuesday the 18th of August onward, when a proper pulse of energy rolls in and the winds finally play nice.
For the first week, from Saturday the 8th through Sunday the 16th, it’s pretty grim. Swell heights are tiny, mostly 1ft to 2ft, and the wind is often onshore or cross-shore, leaving the surface bumpy. The combined energy is weak to moderate (217 to 485), and the period is all over the place, but mostly long-period groundswell that won’t have any push. Keep your expectations low. The water temperature is 61°, which is a touch warmer than usual for this time of year, so at least you won’t freeze while you’re sitting there waiting for a wave.
The real standout is Tuesday the 18th of August. The morning brings a 5ft swell from the SW with a short 9-second period, producing a solid 960 combined energy, and the wind is offshore from the ESE at 12 mph. That’s clean, powerful, and punchy. The afternoon is even better for experienced surfers: 4ft from the W with a 13-second period, energy ramping up to 1057, and the same offshore breeze. That’s the best of the whole forecast. Wednesday the 19th is also good, with the wind holding offshore and clean 4ft to 5ft waves.
The standouts are definitely the 18th and 19th of August. Cox Bay is a beach and point setup, so the long-period groundswell on the 18th afternoon might wrap a bit too straight across the beach, but the offshore wind will groom it into shape. The 3ft glassy conditions on Monday the 17th afternoon are also a nice little warm-up, with clean, user-friendly waves.
After that, the swell fades out and the wind turns onshore again by the 22nd, so get it while you can.
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.
Cox Bay is 77 km (48 miles) from Gold River. If you plan a holiday in Vancouver Island, look for hotels and other accommodation in Gold River. Gold River has rooms for a wide range of budgets as well as car hire and transport links.
