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.
The pattern starts a bit slow, but there's a definite spark of life building. The first few days offer small, clean waves, but they won’t have you screaming; the conditions are absolutely beautiful. Monday the 7th kicks things off with a tiny 2ft SW groundswell, but the wind is dead glass from the NW and it’s just 59° out there – that’s bang on average for this time of year. It’s tiny, but it’s clean.
The real story starts to build from Friday the 11th. Thursday the 10th gets a bit chunky with 6ft to 7ft WNW windswell, but the wind is onshore and choppy, making it a messy affair – more of a kitesurfer's playground than a smooth paddle session. But then Friday morning rolls in with a gorgeous 3ft SSW groundswell, a 17-second period, and light offshore cross-off winds from the SSE. The energy is solid (613) and the surface is clean. Friday afternoon turns even better – glassy calm, 3ft of that same long-period SW swell (527 energy), and the report says it’s “very good.” That Friday is the stand-out window. It’s not big, but the quality is top-tier for a relaxed session.
The weekend and into the following week stay small but consistent. Saturday the 12th is a bit of a write-off with onshore wind in the afternoon, but Sunday the 13th through to Monday the 14th are back to glassy mornings with knee-high clean lines. The energy is light (200-300), so it’s a cruisy longboard zone.
Looking further ahead into the second week, from the 16th to the 22nd, the same pattern holds: persistent SW groundswell, mostly in the 1ft to 3ft range, with period often stretching from 16 to a whopping 19 seconds. The wind looks variable, but there are plenty of glassy pockets, especially on the mornings of the 17th and 22nd. A few afternoons get a cross-shore ripple, but the mornings should reward the early bird with clean, tiny lines. Nothing is going to barrel, but the consistency is there for a log.
Best bet: If you want the cleanest wave of the forecast, paddle out Friday the 11th, especially the afternoon glass-off. 3ft of long-period SSW swell, perfectly clean.
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.
