The Lowdown
Alright, folks. Rusty here. Let's break down what's coming for Cox Bay over the next couple of weeks.
We're starting off a little slow. There's surf on the way, but the first few days are a bit of a mix. The swell is running 3ft to 4ft out of the west, with moderate energy (505 to 620), but the wind is mostly cross or onshore, so the surface isn't going to be super clean. The water temp is about what you'd expect for this time of year, nothing wild.
The first real standout is Friday morning, August 21st. We've got a 4ft west swell with a 10-second period, and the wind goes glassy. That's a proper window. The energy is still solid (420), and with no wind, the surface is going to be like a mirror. It's not the biggest swell, but for clean, fun waves, this is your early session.
The weekend gets a bit choppy. Saturday morning has a 4ft west swell, but the wind is cross-off, so it's rideable, but the period drops to 8 seconds, making for shorter, lumpier lines. The energy is still there (318), but it's not the quality of Friday. Sunday and Monday drop off hard – we're looking at tiny 1ft to 2ft swell with onshore wind. That's a dead zone for a few days. The surf basically goes quiet until the end of the month.
Now, if you've got patience, the real reward is waiting for the very end of the forecast. On Tuesday, September 1st, we get a solid 5ft swell from the west-northwest, with a short 7-second period, but the wind is a clean cross-off from the southeast. The energy is pumping (523), and the light breeze means the wave faces are going to be clean. This is a bigger push, and with the wind working in our favour, it's shaping up to be the best session of the whole run. It's a long wait, but that one looks like the one to mark on the calendar.
Right now, Friday morning is the quick grab, and that Tuesday is the long-range promise. Keep an eye on the wind, but I'd be out there for both.
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.
