The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming down the line for Coronation Beach.
We’ve got a solid run of swell on the way, but the wind is going to be the main character for most of this forecast. The water’s sitting at about 68°F, which is pretty much bang on average for this time of year, so no surprises there.
The first real standout is on Wednesday morning, August 12th. The wind is blowing offshore from the East at 12 mph, setting up a clean, groomed face on the 8 ft SW groundswell. The period is a long 16 seconds, so there’s plenty of energy in the water (combined energy of 3499). This is proper groundswell, and at Coronation Beach, that long period will be working well with the setup. The wave energy is strong, but at 8 ft, this is one for the experienced crew only. Beginners, sit this one out.
Friday morning, August 14th, is another cracker. Same story – offshore East wind at 12 mph, 8 ft SW swell with a 16-second period, and strong energy (3077). Clean, powerful, and consistent. This is excellent surf for those who know what they’re doing.
We then hit a bit of a lull in quality through the weekend and into early next week due to cross and onshore winds. The swell sticks around but the conditions get messy. Monday, August 17th is a write-off with fresh cross-onshore winds and lumpy conditions.
Now, keep your eyes peeled for Tuesday morning, August 18th. The wind drops right out to glassy conditions – a slight air from the South at just 3 mph. The swell bumps up to 10 ft from the WSW, with a 16-second period and very strong energy (4021). This is a serious groundswell, and with glassy conditions, it’s going to be as good as it gets. But again, 10 ft is for experts only. This is the best of the whole outlook.
After that, the wind turns cross-onshore again for the rest of the week, but the swell stays in the 8 ft to 12 ft range. Thursday morning, August 20th sees an 12 ft WSW swell at 15 seconds, but the cross-onshore wind from the NW at 6 mph will put a bit of texture on the face. The energy is very strong (5107), but it’s not as clean as Tuesday.
The second week gets a bit more mixed. There’s a few days of poor conditions with rain and strong winds, but keep an eye on Thursday morning, August 27th. The wind swings to a cross-offshore SE breeze at 12 mph, with a 6 ft SW swell. It’s a smaller day, but clean, and a good option if you’re after something a bit more manageable.
Overall, the standout is Tuesday, August 18th for the expert crew. Wednesday morning, August 12th and Friday morning, August 14th are also excellent. The rest of the window is a game of picking the cleanest windows between the wind shifts.
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.
