The Lowdown

G'day, it's Rusty here. Let's get into what's on the menu for Cox Bay over the next couple of weeks.

We're looking at a mixed bag, starting off pretty flat and grim, but there are two distinct windows of hope. The first few days are a write-off, but once we get through that, some proper glassy conditions roll in, and then there's a solid pulse of swell later on that has the potential to be the real standout.

Right now, from Tuesday the 1st into Wednesday the 2nd, it's a mess. We've got a 2 ft to 4 ft swell coming in from the SSW, but the period is short and the wind from the SE is a cross-off, which is okay, but the energy is weak (297 to 390) and the weather is either cloudy or dumping heavy rain. There's really nothing to get excited about there. Wednesday afternoon shows a bit of a bump to 5 ft from the west, but it's still a bit junky with a moderate cross-off wind.

Thursday the 3rd and Friday the 4th are where things start to look interesting. Thursday morning has a clean 5 ft west swell, but the wind is a light cross-on from the NW, which throws a bit of texture on it. The real gem is Friday the 4th. The morning is clean with a light offshore easterly breeze, and the swell is tiny at 2 ft, but it's a long-period groundswell from the SSW (19 seconds). Then Friday afternoon it gets glassy. The wind drops to nothing, and the swell pushes to 2 ft with an 18-second period. The combined energy is moderate (523), but with those long, clean lines and glassy conditions, it will be a dream for a log or a mid-length. This is the first standout: Cox Bay, glassy, 2 ft from the SSW with that long 18-second period. It's a beginner-friendly break, so perfect for a few cruisy ones.

Saturday the 5th keeps that glassy magic going in the morning. Same tiny 3 ft SSW swell, glassy conditions, and a 17-to-18-second period. The energy is still moderate (542). It's a beautiful, clean morning session. The afternoon turns a bit lumpy as the wind swings cross-onshore, so get out early.

The rest of the first week, from Sunday the 6th through to Tuesday the 8th, is a bit of a letdown. The swell drops off, and the wind is mostly cross-onshore or onshore, making for pretty average conditions. The energy is weak (277 to 416). There's a brief moment on Tuesday the 8th morning with a glassy 2 ft SSW swell, but it's short-lived.

Now, the big news. Look at Thursday the 10th of September. We've got a solid 7 ft west swell rolling in during the morning, with a moderate 12-second period. The combined energy is strong (1813). The wind is a light, clean cross-shore from the SSW. Then Thursday afternoon, it gets glassy. The swell drops just a touch to 7 ft, still from the west, and the energy is massive (1554). This is the second standout, and the biggest swell of the forecast. With glassy conditions and a 7 ft west swell, that's a real clean, powerful wave. This is for experienced surfers only, as it's over 8 ft at its peak. It's not for the faint of heart.

Friday the 11th through to the weekend sees the swell slowly drop back down, with the wind staying mostly cross-onshore, so it's all a bit less clean. The energy drops to moderate (499 to 751).

Then, on Wednesday the 16th of September, we get another pulse of solid swell. Morning is glassy with a 6 ft west swell and a 13-second period. The energy is strong (1253). This is a fantastic, clean, powerful swell, likely for experienced surfers as well. The afternoon gets a bit messy with a cross-on breeze, but that morning session is a beauty.

The water temperature is around 58°, which is about normal for this time of year, so no need for a heavy wetsuit just yet.

Overall, the two real standouts are the glassy, long-period, tiny waves on Friday the 4th and Saturday the 5th morning, and the big, clean, powerful 7 ft west swell on Thursday the 10th afternoon. There's a bit of a dead run from the 6th to the 9th, but it's worth waiting for.

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.
