The Lowdown
Alright, let’s break it down in feet and knots. You’re looking at Cox Bay, and there’s a lot of action coming, but you gotta pick your moments.
The first real surf to paddle for is this Thursday morning, September 3rd. Swell is about 5ft from the west, with a 10-second period, and the wind is dead glass. Water temp is 59°, which is normal for the season. The combined energy is 591 (moderate). It’s clean, fun, and a good one for beginners to get some rides.
Thursday afternoon gets onshore, so that’s it. Friday morning, September 4th, is smaller at 2ft from the SSW, but the period is a huge 19 seconds—super long groundswell. The wind is cross-offshore, so it’s clean. The energy is 444 (moderate). That long period will work best on the point. Friday afternoon, the wind goes glassy again, and the swell is 2ft from the SW with an 18-second period. The energy is 526 (moderate). This is a standout for the glassy conditions and long, powerful lines.
Saturday morning, September 5th, keeps it going with a 3ft SSW swell, 18-second period, and cross-offshore wind. Energy is 525 (moderate). Clean and fun. Saturday afternoon, the rain comes, and it’s less interesting.
Sunday morning, September 6th, is another glassy morning with a 3ft SSW swell, 16-second period, and energy of 454 (moderate). Then we hit a slow patch. From Sunday afternoon through Tuesday, September 8th, the wind is onshore and the swell is small. The energy drops to the 200s (weak). Not worth it.
Wednesday, September 9th, is a mixed bag with cross-shore wind and small swell. Skip it.
Thursday morning, September 10th, is glassy again with a 2ft SW swell and a 17-second period. Energy is 474 (moderate). Clean, but small. The next big standout is Friday morning, September 11th. The swell is 3ft from the SW, 17-second period, and the wind is cross-offshore from the SE. The energy is 588 (moderate). Very clean and long-period, and the wind is your friend. The crowds might show up sometimes, but it’s worth it.
Monday, September 14th, brings a new WNW swell. Morning has a 4ft swell with a 9-second period and offshore wind. Energy is 280 (weak). It’s clean. The afternoon is similar.
Tuesday, September 15th, gets bigger but messy. The swell hits 5ft in the morning and 7ft in the afternoon from the WNW, but the wind is cross-onshore. The afternoon energy is 737 (strong), but it’s choppy and poor. This one is better for the kite surfers.
Don’t miss Wednesday, September 16th, morning. The wind is glassy, the swell is 5ft from the WNW, with a 9-second period. Energy is 522 (moderate). That’s a clean, punchy wave that’s good for intermediate to advanced surfers; it might be too much for beginners.
The last big standout is Friday, September 18th, morning. The wind is dead calm, glassy, and the swell is 2ft from the SW, but the period is a massive 21 seconds. The combined energy is 841 (strong). That’s a very long period groundswell, and it’s going to be super clean. It’ll be best on the point. This is a promising one, but it’s way out there, so keep your fingers crossed.
Rusty out.

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.
