The Lowdown
Alright, Rusty here, let’s talk about what’s cooking at Cox Bay.
Alright, first off, the water temp is sitting about average for this time of year, nothing weird going on there. Now, the good news is there’s a fair bit of swell on the horizon, but we’ve got to wade through a bit of messy stuff to get to the real standouts.
The first real chance for a splash is Wednesday the 22nd. We start the morning with some glassy conditions, a 4.3ft swell from the WNW with a period of 8 seconds, and the combined wave energy is a moderate 409. It’s a short-period swell, so it’s not the most powerful, but with the wind dead glass, it’s a solid option for a beginner-friendly session. The afternoon gets a bit more cross-on, so the morning is your window.
The next few days are a write-off with strong winds, but then things start to get interesting. Friday the 24th afternoon turns glassy again with a 2.0ft, 14-second period SSW groundswell. The combined energy is light at 259, but the period is long, meaning clean, lined-up waves, perfect for a point break like Cox Bay.
Now, the true standout of this whole outlook is Saturday the 25th. We’ve got a very long period swell rolling in. Morning sees a 2.0ft, 24-second period SSW groundswell, with a combined energy of 607. The wind is cross-off and light, so the surf will be clean. By the afternoon, the swell bumps up to 2.6ft from the SW with a 22-second period, and the energy jumps to a strong 762. This is proper groundswell, the kind that brings energy and shape. Because the period is so long, it’ll break best at the point or reef sections of Cox Bay, not so much straight across the beach. If you can get on it in the afternoon, that’s the pick of the fortnight. Crowds are a possibility here, as it’s a known spot.
Sunday the 26th is also worth a look. The morning is a bit cross-on with 2.6ft, 21-second period SW swell (energy 721), but the afternoon turns magic. The wind shifts cross-off and the swell jumps to 3.3ft, 20-second period from the SW, with the combined energy hitting a massive 953. That’s a lot of water moving. Good shape, clean conditions. This is another afternoon session you won’t want to miss.
After that, the week from the 28th onward gets a bit more average. There’s a big energy spike on the 28th morning (1119), but the wind is cross-on and the conditions are marginal. The swell is still 3.3ft from the SW with a 19-second period, so there’s energy, but you’ll be fighting a bit of chop.
The real standouts are clear: Saturday the 25th afternoon is the best on offer for a clean, long-period groundswell. Sunday the 26th afternoon is a close second. For a simpler, glassy session, Wednesday the 22nd morning is your best beginner-friendly bet. Get out there and get wet.

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.
