The Lowdown
Alright folks, Rusty here with the lowdown. Let’s get into the surf for the next couple of weeks.
We’re starting off with some proper energy at Coronation Beach. The swell is coming from the SW, which is just what this spot asks for. The combined swell energy is reading 2465 – that’s a solid amount of power in the water. Water temp is 69°F, which is about normal for this time of year, nothing to write home about.
Wednesday morning is the first call. We’ve got a clean 8ft SW groundswell with a very long period of 15 seconds. That’s real groundswell, so the waves will have that deep-water push, but super-long periods at a beach and reef setup can make them wall up and close out a bit. The wind is a light cross-off at 6 mph, so it’s clean. This is for experienced surfers only – 8ft is big stuff.
Thursday morning is the standout early on. The swell jumps to 8ft from the SW with a 16-second period, and the combined energy cranks up to 3710 – that’s strong. The same light cross-off wind from the SE. It’s gonna be pumping, but it’s expert territory. Don’t get in over your head.
Friday morning keeps the run going with a clean 8ft SW swell. The wind goes offshore out of the ESE at 9 mph. Those are perfect conditions – smooth faces, no bumps. The energy is still up around 2515. If you’ve got the skills, Friday morning is the session.
The weekend and early next week see the swell drop back. Saturday and Sunday are smaller and the wind gets messy, swinging cross-shore and picking up. By Monday the 24th and Tuesday the 25th, the swell really fades. The combined energy drops to 465 on Tuesday, and the waves get small and choppy. We’re looking at a bit of a lull, a few days of flatness.
Then we get a big pulse in the second week. Wednesday the 26th, a new SW swell fills in quickly, hitting 8ft with a very long 17-second period. The energy is strong at 3399. The wind is light and variable, so the morning will be clean. By the afternoon, it’s pushing to 10ft at that same long period, with a massive energy reading of 4635 – that’s some serious, heavy water. Only for the most experienced.
Thursday the 27th holds that size around 8ft, but the wind freshens from the S, and by the afternoon it’s blowing 22 mph, turning the ocean into a lumpy mess. No thanks.
The very end of the period has another golden window. Sunday the 30th afternoon, we’ve got a 7ft, long-period SW swell (19 seconds) and the wind goes glassy – dead calm. The energy is still strong at 3564. That’s a magic moment. Perfect lines with nobody else out possibly. Monday morning the 31st is still clean, but the wind picks up later.
The two true standouts are Thursday the 20th morning and Sunday the 30th afternoon. Thursday has the size and perfect wind, but it’s a beast for experts. Sunday the 30th, with that glassy water and a long-period 7ft swell, is a dream. It’s still big, but that smooth water is what we all chase.
Stay away from the middle of the second week – from the 25th to the 28th, it’s mostly small and chopped to pieces.
Rusty, out.

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.
