The Lowdown
Alright, this is Rusty comin' at ya from Fourth Beach. Let's get into it.
We're looking at a bit of a mixed bag here over the next couple of weeks. The first few days are a bit of a tease – there's swell around, but the winds and conditions just aren't playin' ball. It's not until a week from now, on Monday the 21st, that things really start to fire up. There's a bit of a lull before that, so don't get too amped for the early part of the week.
The real standout, and I mean the one to circle on your calendar, is Monday the 21st. The morning is looking prime. We've got a solid 8ft SSW groundswell rolling in with a long 15-second period. The energy is strong, and the wind is howling offshore from the north. This is the kind of morning that'll have the hairs on your arm standing up – clean, lined-up, and powerful. This is expert territory though; 8ft is no joke, so leave the foam boards at home. The afternoon on the 21st gets a bit wild with a strong offshore breeze making it a battle to paddle into.
Then, just when you think it's over, Wednesday the 23rd morning delivers another absolute beauty. Another 8ft SSW swell, this time from the SW, with a light offshore northerly breeze. The energy is even bigger, and it's clean as a whistle. Again, this is for experienced surfers only.
As we push into the final week of September, it gets proper heavy. By Friday the 25th, the swell is predicted to be a massive 16ft with a 19-second period. That's insane energy. The notes say it's just too big for this break, and with onshore winds, it's a pass unless you're a tow-in crew on a mission. The following days drop back into the 10ft range but are mostly onshore and messy.
The water temp is about average for this time of year, so a 3/2 wetsuit should be fine.
So to sum it up: the first week is a write-off. Lock in the morning of Monday the 21st and the morning of Wednesday the 23rd for the cleanest, most powerful waves. Everything else is either too small, too windy, or too damn big.
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.
