The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ for the next couple of weeks.
Straight up, it’s a mixed bag. We’ve got a real long period groundswell pushin’ through Wednesday and Thursday, but the wind is gonna be a problem for most of the opening stretch. The real gold is sittin’ a week away, with a glassy Thursday afternoon that has my mouth watering.
Cox Bay is a beach and point set-up, exposed to the west. The water temp is about average for the time of year, so nothing freaky there.
We start Wednesday morning, the 29th of July. There’s a 4ft swell from the SW but it’s a long period (17 seconds) groundswell. The problem is a 3 mph onshore wind from the WSW. The wave energy is moderate (903) but the onshore wind is gonna mess it up. It’s a marginal session. The afternoon stays onshore, with a 3ft SSW swell, energy dropping to 676.
Thursday the 30th is a step up. Morning brings a 3ft SSW swell with a 16-second period, and the wind switches to a cross-offshore from the SSE, blowing at 6 mph. The energy is still moderate (636) but those cross-off winds will be cleaning it up nicely. This is a good window. The afternoon gets a bit cross-shore, so the morning is the pick.
Friday the 31st keeps the quality going. Light rain on the morning session, but the wind is a clean cross-off from the ESE at 9 mph. The swell is a smaller 2ft from the SW, but with a 15-second period, it’ll have plenty of push. Energy is moderate (547). The afternoon is even better with a 3ft SSW swell and a cross-off SE breeze at 6 mph, giving us clean lines and an energy of 717. This is a solid day.
Now we hit a dry spell. Saturday the 1st of August is a write-off with rain and onshore wind, and Sunday the 2nd is poor with a short, messy 8-second swell. Monday the 3rd and Tuesday the 4th are also weak and ordinary, with small swell and poor conditions. Tuesday morning the 4th is the only bright spot: glassy, but the swell is tiny (3ft, with only 155 energy). It’s a gap of about four days of poor to no surf.
Then, Wednesday the 5th of August, things get interesting… and a little dangerous. The morning sees a big 10ft swell from the WNW, but it’s only a 9-second period and the wind is light onshore. The energy is very strong (1823). That’s a lot of power, but the onshore wind will make it a beast. This is a big-wave day for experts only. The afternoon is even worse with a 12 mph onshore wind.
The Standout Windows are Thursday the 6th and Friday the 7th of August.
Thursday the 6th is the best of the whole forecast. The morning has a 6ft WNW swell (9-second period) with a cross-off SSE breeze at 6 mph. The wave energy is moderate (580) but the wind is doing all the work to make it clean. The afternoon is absolute magic: glassy, with a 6ft WNW swell and 520 energy. It’s clean, lined up, and there’s power in the water. This is the one.
Friday the 7th is also a cracker. The morning has a 5ft WNW swell with a light cross-on wind, but the afternoon goes glassy again with a 5ft WNW swell. The energy is moderate (374) and the glassy conditions will make it super fun. Crowds are a possibility at Cox Bay, so get there early.
The second week looks a bit more average. The swell sticks around but the wind is tricky. Saturday the 8th and Sunday the 9th are marginal with cross and onshore winds. The energy is moderate (440-450) but the quality isn’t there. Monday the 10th through Wednesday the 12th are all onshore or cross-on, with moderate energy, making for ordinary conditions. The 12th of August afternoon sees a new 2ft, 18-second groundswell from the SSW, but a 9 mph onshore wind messes it up. The 13th of August is similar, small and cross-on.
So, to sum it up: the first few days are okay, but the real prize is Thursday the 6th of August. That glassy afternoon with head-high, clean WNW swell is the best on offer. The Friday afternoon is a close second. The rest is a waiting game.
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.
