The Lowdown
Howdy, Rusty here. Coronation Beach has a solid 16-day window ahead with some serious swell on the cards. The first bits are the ones to jump on.
It all gets going Friday afternoon, August 21st. You’ve got a clean 7ft SW groundswell with a long 15-second period. The wave energy is moderate (2175) and it’s glassy – a proper session for experienced surfers. The water is 67°, pretty much average for this time of year. Saturday morning the 22nd still has a 5ft SW swell, but an onshore breeze ruins it, and it gets worse with rain and strong cross-shore winds through the weekend. You'll have a few days of junk.
The next real standout is Monday morning, August 24th. Clean 7ft SW swell, glassy, with moderate energy (1647). This one’s for the experienced crew. Tuesday the 25th will be smaller at 4ft SW but glassy and very clean.
Then things get heavy and messy. By Wednesday the 26th, we’ve got 8ft to 12ft SW swell with strong energy (5091 to 7860) but onshore winds make it blown out – this is more of a kite session. Thursday the 27th the swell stays big at 8ft but a cross-offshore wind keeps it clean for the experts.
The second week the swell backs off. Friday the 28th and Saturday the 29th have smaller SW swells (5ft down to 2ft) with clean offshore breezes. Sunday the 30th sees a 7ft SW groundswell return with a very long 18-second period and clean conditions. That long period groundswell produces nice, powerful waves but can break straight at the beach – it’s better on a reef or point, but the clean conditions make it a good bet for experienced surfers here.
The final top pick is Monday morning, August 31st. A 6ft SW groundswell, 18-second period, with gentle offshore winds – glassy, clean, and excellent for the experienced. The swell is coming from the SW, the best direction for this exposed spot. Crowds are possible, so get in early.
Into September, Tuesday morning the 1st offers a 7ft WSW groundswell with clean conditions, and Wednesday morning the 2nd is glassy with a 6ft SW swell – both excellent for the experienced. The rest of the week holds 7ft to 8ft SW swell but gets lumpy with cross-shore winds.
Look out for the long-range around Thursday and Friday, September 4th-5th. There’s a 7ft to 8ft SW swell with a 16-second period and good energy (2754 to 3041), but the winds look cross-shore. It’s promising but less certain that far out.
Rusty.

Information about the Coronation Beach Surf forecast
The above surf forecast table for Coronation Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Coronation Beach can be found by selecting the local surf guide option on the grey menu. Our Coronation Beach 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 (Coronation Beach) 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 Coronation Beach 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.
