The Lowdown
Alright folks, Rusty here. Let's have a look at what Cox Bay has in store for us over the next couple of weeks. We're looking at a long-range outlook here, so don't lock anything in too tight for the far end, but there's some promise on the horizon.
The overall pattern is pretty low-energy to start, with a few clean windows popping up here and there. The real standout action looks to be further out, so patience is the name of the game. The water temp is about average for this time of year, nothing wild there.
We kick things off on Thursday, August 13th. The morning session at Cox Bay is actually the best of the near-term. We've got a clean 1.3 ft swell from the SW with a very long 16-second period, and a light cross-off breeze. The combined energy is moderate at 233. It's not big, but that long-period SW groundswell will be a treat on the point, offering up some fun, rippable lines. The light breeze will keep it glassy. Thursday afternoon turns a bit onshore and messy, so hit it early.
Friday, August 14th, starts with a similar 1.6 ft swell and a clean look, but the conditions are described as very ordinary, so it's probably a pass. The weekend of August 15-16 looks pretty average. The swell bumps up a bit (2.3 ft to 2.6 ft), and the energy picks up (up to 514 on Saturday afternoon), but the wind is mostly onshore or cross-onshore, making for lumpy, unappealing waves.
The start of the following week, August 17-18, is more of the same: waist-high plus swell with marginal conditions. Tuesday the 18th has some clean-ish morning windows with light cross-shore wind, but nothing to get excited about. Wednesday the 19th sees the swell push to a full 3.3 ft from the W, but the period drops to 12 seconds, and the wind is not ideal.
Now, here's where it gets a little more interesting. Thursday, August 20th, the morning shows a clean-ish window with a 2.3 ft SSW swell (16-second period) and light cross-onshore wind, offering a moderate 521 energy. Friday, August 21st, is a notable step up. We've got a clean morning with a 2.0 ft SSW swell and a nice cross-off breeze, but the real standout is the afternoon: a 3.9 ft W swell with a 10-second period, clean conditions thanks to a light cross-off wind from the SSE. That's the best size and cleanest combo in the whole forecast. The combined energy is a solid 441 (moderate).
Saturday, August 22nd, the swell peaks at 4.6 ft but the period drops to a junky 6 seconds from the WNW with onshore wind. That's more of a windswell mess, maybe something for the kites, but not for a paddle board. Sunday and Monday (Aug 23-24) drop back down to tiny 1.3 ft - 1.6 ft surf. The absolute standout, if you can wait, is Monday afternoon, August 24th. The swell is a clean 1.6 ft from the SW with a long 18-second period, and the wind goes completely glassy at 0 km/h. The combined energy is 265 (moderate). That's about as perfect as it gets for a small day – silky smooth lines on the point. After that, the rest of the run looks small and wind-affected.
So, for the best on offer: Cox Bay (Thursday morning, August 13th) is your early call for a clean, long-period treat. But the true standout for the whole period is Cox Bay (Monday afternoon, August 24th) – glassy conditions and a clean long-period groundswell. Don't sleep on it. For the second week, Friday afternoon, August 21st is your best bet for a bit more size that's still clean.
Take care, and I'll see you in the water.

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.
