Alright, mates, Rusty here. Let’s break down the next couple of weeks for Coronation Beach.
The main story is a consistent run of SW groundswell, but you’ve got to pick your windows. Water temp is a normal 68°F for this time of year, nothing out of the ordinary.
We start on the afternoon of Thursday the 13th with a clean 8ft SW groundswell, a long 16-second period, and strong wave energy (3470). The cross-off breeze keeps it clean, but that size is for the experienced crew only. The real standout is Friday the 14th morning – same 8ft SW groundswell but with a proper offshore wind from the east at 12 mph. That’s your top call for the first stretch. Clean, powerful, and lined up.
Friday afternoon the wind shifts cross-off and the swell backs off a little. Saturday the 15th drops to 6ft with a shorter 14-second period, still fun with cross-off wind. Sunday the 16th gets smaller and messier with an afternoon cross-on breeze. Monday the 17th is a total loss – strong onshore winds and rain, the ocean is a washing machine.
Now, lock in Tuesday the 18th morning. That is a serious standout. A solid 10ft SW groundswell with a 16-second period, massive wave energy at (5338), and glassy, dead calm conditions. That’s expert-only territory – glassy, heaving, perfect. The afternoon gets a bit of cross-on chop, but that morning is the absolute peak of the forecast. The swell stays between 6ft and 10ft through the rest of the week, with clean windows on the 20th and the morning of the 21st, though the wind is more side-shore.
Into the following week, things settle. The morning of Saturday the 22nd has a clean 7ft SW swell with light offshore wind. Sunday the 23rd morning is smaller at 5ft but clean. Monday the 24th is blown out with strong cross-on winds – skip it. Tuesday the 25th is onshore and messy.
But don’t worry, there’s another good window. Wednesday the 26th morning brings back a clean 8ft SW swell with light cross-off wind. Then Thursday the 27th morning is a corker – 8ft SW, 16-second period, and a very light cross-off breeze. Wave energy is pumping at (4995). That’s a top-quality session for the experienced lot. Friday the 28th stays solid but side-shore. If you’re experienced, the mornings of Tuesday the 18th and Thursday the 27th are the gold. For everyone else, the cleaner, smaller mornings around the 22nd and 23rd are the go.
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.
