The Lowdown
G’day, it’s Rusty. Let’s get into it. We’ve got a solid run of SW groundswell coming into Coronation Beach over the next couple of weeks. A few clean windows stand out, but there’s also some big, windy stuff to dodge. The water temp is sittin’ about average for this time of year, so nothin’ crazy there.
The action kicks off Friday morning, August 21. Coronation Beach is firing with a 8ft SW swell, 15-second period, and a gentle east offshore breeze. That’s clean, punchy, and the swell energy is strong at 2482. This one’s for experienced surfers – the size and power are real. Friday afternoon holds up okay with a 7ft SW swell and a cross-off wind, but a bit more breeze.
Saturday the 22nd is a write-off – rain, onshores, lumpy. Sunday the 23rd is even worse with 19 mph southerlies and weak 4ft surf. That stretch of poor conditions runs through Sunday. Monday morning the 24th is a standout: 7ft SW, 15 seconds, light SSE cross-off. Clean again, strong energy (1915), and that’s a beauty for the experienced crew.
Tuesday the 25th morning is glassy with a 5ft SW swell and 12-second period. Energy is moderate (726), but it’s clean and fun. Wednesday the 26th gets gnarly – an 12ft SW swell with 19-second period hits in the afternoon, and the energy is huge at 17017. But that’s onshore and too big for most, definitely experts only. The entire week from here on is mixed.
Thursday the 27th is lumpy with 10ft SW and strong southerly winds. Friday the 28th morning is another clean shot: 7ft SW, 13 seconds, light SSE cross-off. Energy is moderate (1387). Then it fades into a flat, windy tail through the weekend. By Monday, August 31, we get a ripper – glassy conditions, 8ft SW swell, 18 seconds, and energy of 4434. That’s a proper morning for experienced surfers, clean and powerful.
Tuesday, September 1, morning is glassy again with 7ft SW, 15 seconds, and strong energy (2233). Wednesday the 2nd morning is clean with 7ft SW, 14 seconds. Thursday the 3rd morning gets big again – 12ft SW, 18 seconds, energy 7451, and cross-off wind. That’s expert territory, but clean. The last few days drop off into windy, lumpy conditions.
The true standouts are the Friday morning the 21st, Monday the 24th morning, Friday the 28th morning, Monday the 31st morning, and Tuesday the 1st of September morning. Of those, the Monday the 31st morning is the pick – glassy, 8ft SW groundswell, and that long period is perfect for a beach-and-reef setup like Coronation if you know where to sit. The long period (18 seconds) means there’s plenty of energy but longer lulls, so paddle out easy. Crowds are possible here, so get in early.

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.
