The Lowdown

Alright folks, Rusty here. Let’s take a good, hard look at what’s on the table for the next couple of weeks. I’ll be honest with you, it’s a bit of a slow burn to start. The first solid recommendation doesn’t pop up until Thursday the 13th, so don’t rush to wax your board yet. We’re looking at a few days of mostly small, onshore junk before we get a proper window.

The first real glimmer of hope comes Thursday morning, the 13th of August, at Cox Bay. We’ve got a 4 ft swell rolling in from the WNW with a short period of just 7 seconds, so it’s windswell, not the most powerful stuff. The wind is light cross-offshore from the SSE, which will keep the surface pretty clean. The wave energy is moderate (267), but it’s the first morning where you’re not fighting the wind.

We take a step back for a few days after that, with more small, onshore slop through the weekend and into early next week. But keep your eyes on Tuesday the 18th of August. Tuesday afternoon at Cox Bay is looking magic. The wind goes glassy, dead calm from the west, with a 3 ft SSW swell. The energy is moderate (387), and the water is about a touch warmer than normal at 61 °F. Glassy conditions in the afternoon are rare, so if you can get out there, that’s the call.

The absolute standout of the whole run, though, is Wednesday morning, the 19th of August. This is where it gets exciting. We’ve got a clean 3 ft swell from the west with a period of 12 seconds. That’s a proper groundswell. The wind is a light cross-offshore south-southeasterly, blowing straight down the line. The total energy is ramping up to a solid 521, which is a very healthy push. The waves will have some proper shape and power, and it’ll be clean. That morning is the one to circle on the calendar.

After that, we fade back into smaller, crummier conditions with onshore breezes through the rest of the week and into the weekend of the 22nd and 23rd. We do see another small window on Tuesday the 25th of August, with flat calm, glassy conditions and a tiny 1 ft SW groundswell (period 16 seconds). The energy is low (169-212), but for a long-period glass-off, it might just be the only rideable game in town for a beginner. That’s far out though, so don’t bank on it just yet.

Overall, the best bet is Wednesday the 19th of August morning. It’s not giant, but for clean, lined-up surf, that’s the standout. Get it while it’s 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.
