The Lowdown
G’day, Rusty here. Let’s break down what Coronation Beach has cookin’ over the next 16 days. Plenty of swell on the menu, but the wind’s gonna be the chef.
Monday 17 August starts flat as a pancake with a strong 30 km/h cross-onshore wind messin’ up a 1.6m SW swell – energy reading 2176, which is moderate but the wind kills it. The afternoon gets bigger at 2.5m but same bad wind. No go.
Tuesday 18 August morning is a full-on standout. Coronation Beach gets glassy with a light 5 km/h ENE offshore wind and a thumping 3.5m SW groundswell. That’s 12 feet, with a 17-second period and very strong energy of 6187. This is big-wave territory – only for experts. The wave shape will be clean and powerful. Water temp is 19°, about 0.7° cooler than average – nothin’ weird, just normal winter chill.
Tuesday afternoon the wind turns cross-on, swell drops a bit to 3.0m, gets a little lumpy. Wednesday 19 August through Thursday 20 August has 2.2m to 2.5m SW swell, clean mornings with a light cross-offshore SE breeze, but the afternoons get marginal. Good for the experienced crew.
Friday 21 August morning is another highlight: offshore E wind at 20 km/h, 2.2m SW swell, 15-second period, energy 2208. Clean, offshore lines. Excellent for experienced surfers. A solid pick.
Saturday 22 August the swell drops to 1.7m in the morning, still clean but nothin’ to write home about. The afternoon gets cross-shore and bumpy.
Sunday 23 August onshore wind ruins the 1.9m swell. Monday 24 August through Tuesday 25 August is mostly onshore, choppy, and messy. Stay home.
Wednesday 26 August morning bounces back: clean cross-offshore SSE wind, 2.1m SW swell, 16-second period, energy 2552. Excellent for experienced surfers. Good session.
From Thursday 27 August to the end of the run (1 September), swell stays between 1.6m and 2.4m, mostly clean in the mornings. Tuesday morning 1 September is the last decent window: clean cross-offshore wind, 1.7m SW swell, 15-second period, energy 1310. Not huge but smooth.
The absolute best is Tuesday 18 August morning with that glassy 3.5m beast, and Friday 21 August morning for clean offshores. Everything else is just filler.
Crowds can stack up here, but with this size swell it’ll be just the hardcore crew out.
Stay safe. 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.
