The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the menu for Cox Bay over the next couple of weeks.
Right off the bat, we've got a bit of a slow start. The first real chance to get wet is on Friday, July 31st. A solid 2ft groundswell from the SW, with a long 15 second period, will be pushing in. The energy is moderate (571), and with a light cross-offshore breeze from the SSE, things are looking clean. This is a good pick for the early session, but it's a beginner-friendly wave, so don't expect any heavy barrels.
The weekend looks pretty average. A little bump on Saturday, but onshore winds mess it up. Sunday sees a bit more size, up to 5ft, but it's a short-period, onshore mess. Honestly, not worth paddling out for.
The first real standout comes mid-week. On Wednesday, August 5th, the morning is looking magic. We've got a building 5ft swell from the WNW, with a moderate 8-second period, and it's glassy. The energy is solid (371), and the description says "expect good surf conditions". That's the session to aim for. The wave is a bit bigger, so it'll be more for the crew with some experience.
Thursday, August 6th, also has a good window. The afternoon session sees a 4ft WNW swell, again glassy, and manageable. It's a consistent option for a late arvo paddle.
After that, things drop right off. The second week is a low-energy affair. There's a fun little window on Tuesday, August 11th, with a 2ft, 16-second groundswell from the W, and a clean cross-offshore breeze. The energy is moderate (317), but it's a tiny wave for the longboard or a fish. The water temperature is about average for the time of year, no real surprises there.
The biggest energy of the whole period pops up on Thursday, August 13th, with a 4ft swell from the W and a huge energy reading (1006), but it's getting chopped up by a solid 12 mph onshore breeze. Not a surfable option unless you're on a kite. That same day, the morning shows a 2ft SW swell with a very long 18-second period and strong energy (501), but it's onshore again. A real shame, because that groundswell would be gold at a point break.
The last call of the run is on Saturday, August 15th, with a 5ft WNW swell, but it's a short period (7 seconds) and a cross-onshore wind. It's a marginal option for the desperate.
So, to wrap it up: Friday morning, July 31st is your best early bet, and Wednesday morning, August 5th is the clear standout for the best quality waves. The second week is mostly a wait-and-see game, with only a few tiny, clean windows.
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.
