The Lowdown
G’day, I’m Rusty. Let’s break down the waves for Coronation Beach. We’ve got a solid stretch of surf starting this Wednesday morning and running right through to Thursday the 3rd of September – that’s over two weeks of action. No gap at the start, we’re into it straight away.
The story here is a classic winter SW swell train, with clean mornings and afternoons getting a bit choppy. Water temp is about normal for this time of year.
The standout is Thursday morning, the 20th of August. You’re looking at 8ft of SW groundswell, with a long 16-second period, and the combined swell energy is cranking at 3710 – that’s powerful. Winds are light SE cross-off, so it’ll be glassy clean. This is strictly for experienced surfers – that size and power is no joke. The break is exposed, a beach-and-reef setup that’ll handle it.
Wednesday morning the 19th starts us off with 8ft SW swell, 15-second period, and a cross-off SE breeze at just 3 mph – dead clean. Combined energy is 2465, solid. Again, only for the experienced crew. Wednesday afternoon gets a bit lumpy.
Friday morning the 21st is another clean one: 8ft SW, 15 seconds, offshore E wind at 9 mph. Combined energy 2547. Excellent conditions, but expert only.
Saturday morning the 22nd is a beauty – the swell drops to 5ft but the period stretches to 18 seconds, a very long groundswell. The wind goes glassy, NW at 3 mph. Combined energy is 2588. That long period means the waves will set up nicely at this point break, with clean lines and long waits between sets. Still too big for beginners, but a dream for the confident surfer.
Sunday the 23rd and Monday the 24th see the swell ease a bit. Sunday morning is 5ft with clean cross-off, but combined energy drops to 986 – moderate. Monday morning picks back up to 6ft SW, 15 seconds, with light SE cross-off and clean.
Tuesday the 25th is a quiet day, only 4ft and 4ft, not much happening.
Then Wednesday the 26th brings a big pulse – morning has 8ft SW, 16 seconds, combined energy 3844, and afternoon jumps to 10ft SW, 17 seconds, energy at 5043 – very strong. The wind is cross-shore though, so it’ll be choppy. Only for the brave.
Thursday the 27th morning looks good again: 8ft SW, 15 seconds, cross-off S wind at 6 mph, clean. Friday the 28th and Saturday the 29th fade out, with Saturday morning only 2ft but a long 18-second period – combined energy 640, weak.
Sunday the 30th has 6ft SW, 16 seconds, with cross-off SE wind, clean but moderate energy.
Monday the 31st of August is a nice finish – morning has 4ft WSW swell, 17 seconds, offshore E wind at 16 mph, clean. Combined energy 1480. Afternoon bumps to 6ft SW, 16 seconds, gentle offshore ESE, energy 1742. Both clean and good for a confident intermediate.
Tuesday the 1st of September drops off, and Wednesday the 2nd sees another 8ft SW pulse, but onshore wind, so messy. Thursday the 3rd is similar with onshore wind.
So the best of the bunch is Thursday morning the 20th of August for the strong, clean, powerful SW groundswell. Saturday morning the 22nd is the other standout for its glassy conditions and very long period. If you’re a beginner, wait until the swell drops under 5ft, like Monday the 31st morning, but even then it’s not ideal for learning.

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.
