The Lowdown
Alright, grab your wettie, because the next couple of weeks here at Fourth Beach are a bit of a rollercoaster. This break is a fairly exposed spot that loves a solid SSW push, so when the stars align, it pumps. Right now, there's a lot of cross and onshore junk to sift through, but patience will pay off.
The tricky part is the first week. The wind is all over the shop, mostly onshore or cross-off, which is going to leave us with choppy, lumpy conditions through the 11th, 12th, and 13th. There will be some size – we are looking at a 6ft SSW swell on Friday the 11th afternoon and a bigger 8ft SW swell on Saturday the 12th – but the wind is just going to rip it apart. Sunday the 13th offers a 6ft SW swell with a 14-second period, but it's cross-shore and messy. It's going to be a wait-and-watch situation.
The standout session is shaping up for Saturday, September 19th. The morning actually gets a 13ft SW swell which is way too big and powerful for anyone but the bravest experts. But hold on for the afternoon. The wind swings to a glassy SE breeze at just 3 mph and the swell drops to a still-very-strong 10ft, coming from the SW with a solid 11-second period. That is going to be a heavy, glassy wall for experienced surfers only – absolutely pumping, but you better know what you're doing. The water temp is sitting at about 17°, which is pretty much standard for this time of year, so a spring suit is the go.
After that, we get another pulse right on Monday, September 21st. The early call is a massive 13ft SSW with a long 16-second period and an onshore wind – that’s a beast for the top guns. The Tuesday the 22nd morning is the absolute sleeper hit: a clean 10ft SSW with glassy offshore NW wind at just 3 mph. That’s prime, clean conditions on a powerful, long-period groundswell, but remember, with a period that long, you'll want to be looking for the peaks that aren't just closing out. It’s going to be sick for those who can handle it. The further out stuff around the 24th and 25th is still promising, with 8ft to 10ft SSW swells and decent period, but the winds are looking more onshore again, so keep an eye on that.
All in all, there’s some serious power coming, but you have to pick your windows. The 19th and 22nd are the ones to circle. Be ready.

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.
