The Lowdown
G'day, Rusty here. Let's have a look at what's on the cards for the next couple of weeks.
We've got a solid run of south-west groundswell heading our way over the next week, with some decent size and those long, juicy periods that get the blood pumping. The water temp is sitting at 67°, which is bang on average for this time of year, so no need to dig out the extra thick steamer just yet.
The standout of the whole window is without a doubt Thursday morning, 20 August at Coronation Beach. We're looking at a clean 10ft SW groundswell, with a period of 16 seconds and a light cross-offshore breeze. The combined energy is pumping at (3929), and the conditions are clean. This is proper, powerful groundswell with a lot of energy behind it—over 8ft, so it's strictly for the experienced crew. For a beach and reef setup like this, that long period will make for some grinding, lined-up waves, but it can be a bit shifty.
Before that, Wednesday morning, 19 August is another beauty. The swell has dropped a touch to 8ft from the SW, but the wind is glassy—absolutely dead calm. The energy is still strong (2465), and those conditions will make for some smooth, clean faces. Still a solid size, so keep it for the advanced surfers.
We then get a few more mornings with good potential. Friday morning, 21 August, the swell holds at 8ft from the SW, but we get a light offshore breeze out of the east, making for clean conditions. The energy is still pumping (2534). Monday morning, 24 August sees the swell drop to 6ft, but it's glassy again, and the crowd factor is "sometimes", so it's a good chance for a quieter session. Then Thursday morning, 27 August, the swell is back up to 8ft from the SW with a light cross-offshore breeze and clean conditions. The energy is solid (2216).
After the first week, the surf drops off sharply. There's a gap of a few days with very little to get excited about, but the run picks up again on Saturday morning, 29 August with a 5ft SW groundswell and a very long, clean period of 17 seconds. It's glassy, and the energy is moderate (1521). A good one for the points and reefs. Monday morning, 31 August offers a 5ft SW swell with a moderate offshore breeze out of the east—clean and a bit more accessible.
The final standout is a bit further out, so keep an eye on it. Tuesday morning, 1 September, we see a 7ft SW groundswell with a very long period of 18 seconds. The energy is strong (3374), but the wind is a light cross-onshore, so it might be a little rippled. The size is still hefty, so it's one for the experts to watch.
There's some solid size and long-period groundswell on offer here, but most of the bigger stuff is for the experienced crew. The glassy mornings and clean conditions early on are where it's at.

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.
