The Lowdown

Alright folks, Rusty here. We’ve got a full 16-day window for Cox Bay, and it’s a bit of a mixed bag, but there are some real gems if you’re patient. Let’s get into it.

The pattern starts slow, but hang tight. The first decent surf kicks off on Sunday, August 30th. It’s not gonna blow your mind, but it’s a start. The water temp is sitting pretty average for this time of year, so no surprises there.

Sunday morning is a bit cloudy with a light cross-offshore breeze from the SE at 6 mph. The swell is a clean 3 ft from the SW with a very long period of 17 seconds – that’s a proper groundswell. The combined energy is moderate (498). That long period means the waves will have shape, but it might be a bit fat and straight on the beach, so keep an eye on the point. It’s a clean session for the patient ones.

Sunday afternoon goes glassy with a tiny 3 ft from the SSW. The wind is dead calm at 3 mph. Perfect for a longboard or a funboard. The energy is a bit lower (396), but the conditions are sweet.

Monday, August 31st, is where it starts to get interesting. The morning is crystal clear, with glassy conditions again. The swell holds at 3 ft from the SSW, but the energy jumps up to 505. The period is still a very long 16 seconds. This is a quality window. The afternoon gets a bit messy with onshore wind, so make the most of the morning.

The next few days are a bit of a write-off. Tuesday has some cross-shore wind, and Wednesday, September 2nd, is a total washout with heavy rain and strong winds hitting 25 mph. The swell jumps to 4 ft, but it’s a short-period windswell of 8 seconds. The energy is moderate (387), but honestly, it’s a skip day. Thursday is also a no-go with onshore winds.

Friday, September 4th, sees a return to cleaner conditions. The morning is clear with a light cross-offshore breeze. The swell drops to 2 ft, but it’s a very long period of 19 seconds – that’s about as long as it gets. The energy is moderate (425). It’s a longboard special.

The first true standout is Saturday, September 5th. The morning is a dream. Zero wind, glassy as a mirror. The swell is 3 ft from the SSW with a period of 18 seconds, and the combined energy is a solid 553. The conditions are just about perfect. Crowds are possible here, so get in early for the glassy sets.

Sunday, September 6th, is a bit of a letdown. The morning is clean, but the afternoon gets a 5 ft short-period windswell from the WNW with only 8 seconds. That’s a choppy, messy affair.

The second week is a bit more of a gamble. The forecast is less certain, but there are some promising signals. Monday, September 7th, is not great. Tuesday has onshore wind. Wednesday, September 9th, looks promising with a light cross-offshore breeze and a 4 ft swell from the WNW. The energy is strong (603), and the period is moderate at 10 seconds. It’s a clean morning.

Then we get to the second standout: Thursday, September 10th. The morning is glassy again, with a 4 ft swell from the WNW. The wind is dead calm. The energy is moderate (515). The afternoon gets a bit bigger at 7 ft, but the period drops to 6 seconds and the wind picks up, making it choppy. So, the morning window is the one to score.

Friday, September 11th, brings a bit more size. The morning has a 6 ft swell from the SW with a very short period of 6 seconds. The energy is strong (751), and the wind is a light cross-offshore. This is punchy, short-period stuff. It’s an expert-only wave at that size, and the short period means it’ll be a bit of a wrestling match.

Saturday, September 12th, starts with a glassy 6 ft from the W. The energy is strong (873). The wind is dead calm. This is a solid, clean morning for experienced surfers.

Sunday, September 13th, is a bit of a mess with onshore wind, and Monday, September 14th, finishes the run with a glassy morning, 6 ft from the W, and strong energy (743). That’s a nice way to end the forecast.

So, to wrap it up: the absolute best windows are Saturday, September 5th morning for the glassy, long-period perfection, and Thursday, September 10th morning for the clean, moderate-size conditions. The second week is a bit more of a long-range promise, but it looks good.

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.
