The Lowdown

G’day, it’s Rusty. Let’s talk about what’s happening at Cox Bay over the next couple of weeks.

The surf starts off this Saturday morning with a clean 3ft swell from the southwest, a super long 15-second period, and glassy conditions. Water temp is around 58°, pretty normal for the season. The energy is moderate (521), so it’s a fun, easy session but not a powerhouse.

Saturday afternoon goes a bit pear-shaped with a light cross-onshore breeze and the swell dropping to 3ft – best to skip it.

Sunday morning is a beauty: clear skies, a light cross-offshore wind, and a 2ft southwest swell with a 14-second period. Clean, lined-up waves for a longboard. Energy is moderate (373).

Sunday afternoon gets messy – a 5ft short-period (7 sec) west-northwest windswell hits with a cross-on breeze. Choppy and not worth it.

Monday afternoon is glassy with a tiny 2ft swell but a good 13-second period (215 energy) – small but tidy waves.

Tuesday through mid-week stays small, with glassy mornings offering 1ft to 2ft waves and periods up to 19 seconds. Energy is weak to moderate (239–327). Fine for a dawn paddle on a foamie.

Then, Monday the 21st of September is your first standout. Glassy conditions, a 3ft southwest swell with an 18-second period, and very good surf. The combined energy jumps to 505 (moderate). The afternoon is just as good at 547. That long-period groundswell will wrap around the point, giving clean, shapely waves – this is the pick of the first week.

Tuesday the 22nd brings a big 8ft west-northwest pulse (12-second period), but 30 km/h cross-onshore winds make it lumpy and blown out. Energy is very strong (1853) – this one’s for the kite surfers, not the paddle crew.

Wednesday the 23rd snaps back to glory: glassy, a 2ft southwest swell with a 16-second period, and energy of 625. Silky smooth, clean, and spot-on direction – another standout.

Thursday the 24th has a gentle east offshore wind with 4ft waves from the west (10-second period) – clean but not epic.

The 25th and 26th are messy with strong cross-onshore winds, but Saturday the 26th offers a glassy morning with 4ft from the west-southwest (11-second period) and moderate energy of 582. Clean and fun early, but the wind turns later.

Finally, Sunday the 27th is glassy all day with 3ft to 4ft west-southwest swell. Energy is moderate (309–434) and conditions are clean – a mellow end to the window.

To sum up, the best mornings are Monday the 21st and Wednesday the 23rd – both glassy, long-period, waist-to-chest high waves from the southwest. Crowds at Cox Bay can be a problem sometimes, so get there early. The rest is small but often clean, with a few blown-out days.

That’s how I see it.
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.
