The Lowdown
Alright, Rusty here again, switching to feet and Fahrenheit for the yanks.
Fourth Beach is having a rough start to this outlook, and I’m not gonna sugarcoat it. Friday the 4th is a complete mess: 13 to 17ft of SW swell, but with a screaming 30 to 31 mph cross to cross-onshore wind. It’s chaotic out there. Saturday morning the 5th is your first real chance. The wind drops to a light cross-offshore, and you’ve got a clean 10ft groundswell from the SSW with a 14-second period. That’s serious size for advanced crew only. The water is 62°, pretty normal for this time of year. That Saturday morning session is the highlight of the whole board. Saturday afternoon the wind shifts cross-on, and it gets marginal again. From Sunday the 6th through Wednesday the 10th of September, it’s a long run of poor to marginal conditions. The swell stays big but the onshore winds are just relentless.
Thursday the 10th morning offers a clean cross-off breeze but the swell is down to 6ft. It’s a nice, clean, smaller session. Friday the 11th morning is even smaller at 4ft. Then we hit a quiet spell over the weekend of the 12th and 13th. Monday the 14th brings another big pulse, 10 to 13ft, but pinned under a fresh cross-onshore wind. That’s kite-surf territory, not a paddle day.
Now, the end of the run has some serious promise. Tuesday the 15th of September shows a huge 13ft SSW swell, but the guidance says it’s predicted to be just too big for this break. Even for experts, that’s a caution flag. The wave energy is extreme. Your real gem is Friday the 18th of September. The morning delivers a clean 7ft SSW swell with a 16-second period and an offshore wind. That’s a long-period groundswell with great shape, perfect for this spot. The afternoon is also excellent, with 8ft SW swell and glassy conditions. That’s your second standout window. After that, Saturday the 19th is clean but the quality drops off and the wind freshens up.
Bottom line: get out there at first light on Saturday the 5th of September for the big clean 10ft sets. Your other best bet is Friday the 18th of September for that offshore, long-period glass. There’s a long stretch of poor conditions in between from the 6th to the 10th. Don’t force it. The long-range stuff on the 18th looks good, but keep a loose eye on it.
Rusty.

Information about the Fourth Beach Surf forecast
The above surf forecast table for Fourth Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Fourth Beach can be found by selecting the local surf guide option on the grey menu. Our Fourth 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 (Fourth 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 Fourth 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.
