The Lowdown
Alright folks, Rusty here with a look at the waves coming our way.
Right off the bat, we’ve got a decent run of clean, smaller surf on the horizon, but it’s not going to be massive. The real standout energy comes later, with a proper pulse of swell showing up around the end of the month.
Cox Bay is the only spot on the map, and it’s a beach and point setup that’s fairly consistent. The water temp is about what you’d expect for this time of year, nothing weird going on there.
We kick off on Friday the 11th. Morning looks decent with a 3ft swell from the southwest, a long 17-second period (groundswell), and a gentle offshore breeze. The energy is moderate (617), and the report says it feels very good. That’s your best bet to start the period. By the afternoon, the wind shifts and things get a bit messy.
Saturday the 12th is a beauty if you can get out early. Glassy conditions with a 3ft southwest swell and a 15-second period. Wave energy is solid (521), and the call is very good surf conditions. For beginners, it’s a good size. Saturday afternoon sees the wind turn cross-onshore, so the quality drops.
Sunday the 13th brings a bigger but much shorter-period swell – 6ft from the west-northwest, but only 7 seconds. That’s a lot of bumpy, weak windswell energy (760) with cross-shore winds. It’s not the one for clean waves. The wind stays messy into Monday, with a drop in size.
Tuesday the 15th, Wednesday the 16th, and Thursday the 17th are all about small, clean windows. We see glassy mornings with knee-to-waist high swell (2ft to 3ft). Periods are short (7 to 8 seconds), so it’s not a lot of push, but it’s fun for a longboard or a foamie.
Now, here’s the good stuff for more experienced surfers. On Thursday the 24th of September, the swell picks up. We get a 5ft west swell with a 12-second period, and by the afternoon it’s a 5ft west swell, 11-second period, with glassy conditions. The combined energy jumps to 948, making it a moderate-to-strong pulse, and the report says very good surf. This is a real standout for the period, but at 5ft to 5ft, it’s getting into the intermediate zone – not a beginner’s day.
Friday the 25th keeps the fun going with a 4ft west swell and glassy morning conditions. Another good, clean day. The swell backs off again through the weekend, but we see a nice glassy morning on Saturday the 26th with 4ft from the west-northwest.
So, overall: the first week is small but clean, with Saturday the 12th being the pick of that bunch. The real standout is the pulse around Thursday the 24th and Friday the 25th – bigger, cleaner, and much more powerful. That’s the one to circle on your calendar.
Stay stoked, keep your wax warm.

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.
