The Lowdown

Alright folks, Rusty here. Let’s break down what’s heading our way over the next couple weeks.

The start is rough, but there’s a solid stretch of clean, small waves in the middle, and a couple of bigger swells for the die-hards later. The first few days are a write-off for quality surf, so don’t rush down Thursday. There’s a big gap of poor conditions before it turns around.

Thursday the 10th is a total bust. Morning has a 6ft swell from WNW but it’s getting blown onshore by a westerly wind, making for messy conditions. The afternoon is worse – bigger at 8ft but cross-onshore and choppy. Leave the board at home.

Friday the 11th is where it finally gets good. The morning goes glassy with zero wind, and we get a clean 3ft groundswell from the SW with a long period of 17 seconds. That’s proper energy moving into Cox Bay, with moderate power (611). The afternoon stays clean with a cross-off breeze and the swell holding at 3ft with a 16-second period (537). This is the best on offer – small but perfect, and the water temp is 59°, which is about average for this time of year. This is a standout for the clean, glassy morning session.

Saturday the 12th is back to average. Small waves around 3ft to 3ft but with cross-onshore wind and ripples. Not worth the drive.

Sunday the 13th morning cleans up with a cross-off breeze, but the swell is tiny at 2ft. The afternoon bumps to 5ft, but that short-period WNW windswell at 8 seconds will be sloppy with a light cross-onshore push.

Monday the 14th and Tuesday the 15th are both small and mostly clean, but wave heights drop to 1ft to 1ft. You’re looking at ankle-biters with long-period energy but not enough push. Wednesday the 16th and Thursday the 17th keep the tiny theme, though there are some glassy mornings if you’re desperate. Energy is low, in the 190 to 260 range.

Friday the 18th through Saturday the 19th offers a return to clean conditions with cross-off winds and a small but consistent 2ft to 2ft SSW groundswell with very long periods of 16 to 19 seconds. The combined energy stays moderate (328 to 359). This is a nice run of clean, user-friendly waves for beginners. The swell direction matches what the spot likes, and with light, offshore-ish wind, it’s a solid bet for a long session.

Sunday the 20th is a mess with strong WNW winds. Nothing to see.

Now here’s the next standout: Monday the 21st morning. Clean conditions return with a cross-off breeze and a 3ft SW groundswell with an 18-second period. Combined energy is moderate (521). The break is wide open to the swell, and the wind is right. This is another good call for a clean morning surf.

But the real deal for the experienced crew shows up on Wednesday the 23rd. The morning goes glassy again, and we get a 6ft WNW windswell with a short period of 8 seconds. The combined energy jumps to strong (1050). That’s a lot of water moving, but the short period means it will be a bit fat and dumpy. This is expert territory at that size. The afternoon gets even bigger at 8ft but the wind turns cross-on, making it less attractive.

Thursday the 24th morning offers a clean, glassy 5ft W swell with an 8-second period – decent and clean, but not the standout.

The last big window is Friday the 25th. Morning brings an 8ft WNW groundswell with a 7-second period and moderate cross-off winds. Combined energy is strong (840). This is big and powerful, and the afternoon pushes to 10ft with an even higher 1140 combined energy. That’s heavy, expert-only territory with that much power, and it will be clean with a cross-off breeze. If you are a strong surfer, the afternoon of the 25th is the biggest and most powerful session on offer.

Overall, the two standouts are Friday the 11th morning for glassy, clean, small waves for everyone, and the afternoons of Wednesday the 23rd and Friday the 25th for the big-wave crew. The middle period is a consistent run of clean, small waves perfect for beginners.

Keep it real.

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.
