The Lowdown

Alright, let’s get into it. The next couple of weeks are a mixed bag around here. We’ve got a pulse of swell coming in for the start, but we gotta pay our dues with some wind and less-than-perfect conditions before things clean up and get real fun.

We're starting at Cox Bay on Thursday the 10th. The swell is up, around 5.6ft in the morning and pushing 7.2ft by the afternoon, coming from the WNW. The energy is moderate (678) but the period is a short and junky 8 seconds, so it’s gonna be lumpy and all over the place. The wind is cross-onshore and it’s just a battle. It’s surfable but nothing you’d write home about.

Now, Friday morning the 11th is where it changes. The swell drops to a cleaner 2.6ft from the SW, but that period jumps to a solid 17 seconds. That’s proper groundswell, and the energy is still moderate at 602. The wind is dead glassy, and it’s looking like perfection. This is the standout of the whole run. Water temp is about normal for this time of year, so you'll be fine with your usual suit.

That glass holds on into Friday afternoon, with a light offshore breeze from the ESE and the swell still at 2.6ft from the SW with a 16-second period. The energy is still moderate (544). It’s going to be clean, lined-up, and a pleasure. Another great window.

Saturday the 12th the swell eases a bit to about 3ft in the morning, but the wind goes cross-shore and it gets a little ripply. The period is still decent at 15 seconds, but it’s just not as perfect as Friday. The afternoon turns more onshore, so the morning is the call.

Sunday the 13th starts with light cross-offshore winds and a smaller 2.3ft swell, but it’s clean. The period stays at 14 seconds. Small but fun. But the real surprise is Sunday afternoon. The wind goes glassy again, and the swell bumps up to 4.6ft from the WNW with a shorter 7-second period. The energy is moderate (510). The glass will make it super smooth, but that short period will likely make it a bit crumbly. Still worth a paddle.

The start of the next week sees the swell fade. Monday the 14th and Tuesday the 15th are small and glassy in the mornings, with waves around 1.6ft. The long periods are there, but there’s just not enough water moving to get anyone properly excited. It's a good time to fix your gear or just watch.

Wednesday the 16th and Thursday the 17th are more of the same – very small and clean in the mornings but weak. Energy is in the low 200s (226 and 225). A bit of a flat spell.

Then we get a little bump on Friday the 18th. The swell is still small at 1.3ft, but the period jumps to a massive 21 seconds. That’s a very long-period swell, and the energy is moderate at 355. For a spot like Cox Bay, that kind of period can make it break a little too straight, but with the glassy morning conditions, there could still be some fun, clean walls for the patient ones.

The following days into the second week remain small, with the swell hovering around 2ft to 2.6ft. The mornings on Saturday the 19th and Sunday the 20th look clean, with the wind going glassy again on Sunday. The swell is still from the SW with long periods, but the size just isn’t there to call it a standout.

Monday the 21st is a washout. The wind is going to blow from the WNW at 12 mph in the morning, cranking to 22 mph by the afternoon. The surf is only 2.6ft but it will be completely blown out and lumpy. Don't bother. This is a day for something else.

Just when you think it’s done, Tuesday the 22nd and Wednesday the 23rd bring back those beautiful, glassy mornings. The swell is a clean 2.6ft from the SW, with a 16-second period. The energy is moderate (564 and 528). These are looking like really fun, clean days. The consistency will be better on Wednesday with some light cross-offshore winds. These are the pick of the second week.

The last few days, Thursday the 24th and Friday the 25th, are small again. Thursday afternoon could offer up a clean 3.6ft from the west with a short 8-second period, but the energy is low. Friday morning is small, clean, and cross-offshore, and while it’s not big, it will be an easy, cruisy session.

So, to sum it up, the clear standout is Friday the 11th with those glassy conditions and that long-period SW groundswell. It’s going to be the pick of the bunch for quality. The second standout is that Sunday afternoon glassy session on the 13th, and then the glassy mornings on the 22nd and 23rd are worth setting an alarm for.

Overall, not a period of huge surf

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.
