The Lowdown
Alright folks, it’s Rusty here, and I’ve got the skinny on the next couple of weeks for Fourth Beach. It’s a bit of a tale of two forecasts, so let’s get into it.
The overall pattern is heavy on the swell, but the wind is going to be a real pain in the arse for a lot of the time. We’ve got some serious energy rolling in from the deep south, which is great for power, but the onshore and cross-shore winds are going to mess up the surface for most of the first week. It’s an advanced spot, so you need to be ready for a beating, especially when it gets big.
Let’s start with the first real window of opportunity. Saturday morning, September 5th is your best early bet. We’ve got a solid 10 ft swell from the SSW, with a long period of 14 seconds – that’s proper groundswell, pushing a massive 3826 units of energy. The wind is a light 6 mph cross-off from the NW, which will keep the face clean. This is big, powerful stuff, and at 10 ft, it’s strictly for the experienced crew. The water temp is sitting about average for the time of year, so you won’t need a thick wetsuit, but you’ll be glad for a good one.
After that, the wind swings onshore and the surf quality drops off a cliff. From Saturday afternoon right through to the middle of the next week, it’s a write-off. The wind is pumping from the SE, sometimes hitting 25 mph with gusts, and the swell is still huge – we’re talking 8 ft to 12 ft with a long period, but with a cross-onshore mess, it’s just a washing machine. That big swell energy is still there (up to 6708 units), but it’s unrideable for a paddle surfer. Honestly, if you’ve got a kite, this setup might look more interesting than a surfboard.
We get a bit of a reprieve later in the second week. The wind goes lighter and turns offshore again. Friday morning, September 11th, the swell drops to a more manageable 5 ft from the SSW with a 15-second period, and a 12 mph cross-off from the NE will clean it up. The energy is moderate (1115 units), but the conditions are getting better. The real standout in the second week though, without a doubt, is Friday afternoon, September 18th. The swell is a solid 6 ft from the SSW with a 15-second period, but the magic is in the wind – a 3 mph glass-off from the SW. That is the stuff of dreams. The wave energy is moderate (1550 units), but with glassy conditions, that long-period groundswell will line up beautifully. This is the best session on offer, but it’s a long-range call, so keep an eye on it.
The following Saturday and Sunday (September 19th and 20th) look like a washout again with a near gale blowing, so don’t get your hopes up for the end of the run.
All in all, if you’re an advanced surfer, lock in the Saturday morning of the 5th for the raw power, and circle that Friday afternoon of the 18th for the cleanest, most beautiful waves you’ll see in the whole forecast. It’s not a perfect run, but there are two gems in there.
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.
