The Lowdown
Alright folks, Rusty here, taking a look at what's on the menu for Fourth Beach over the next couple of weeks. It's a bit of a mixed bag, so let's get into it.
We’ve got a solid run of south-west groundswell on the way, but the wind is going to be the real boss here. The first few days are a bit of a write-off, with a messy 8ft cross-on swell on Monday, August 24th, and the wind just making a mess of it. The energy is huge though, hitting 2881 (moderate to strong). Tuesday the 25th afternoon shows some promise with a cleaner 5ft swell from the SW and offshore winds, but it's not going to be the standout.
The real highlight looks to be Wednesday morning, August 26th. We’ve got a clean 7ft SW groundswell with a nice 14-second period and a gentle offshore wind from the NNW. The energy is strong at 1875, and the report says it's excellent for experienced surfers. This is your window for some proper, clean lines. For a few days after that, we get hammered by strong onshore winds and building swell, so that’s a no-go.
Now, looking further ahead, there's a big one to circle. Sunday morning, August 30th, is looking like a potential champion. The swell is a solid 8ft from the SSW with a very long 17-second period. The wind is light and offshore from the NNE, and the energy is massive at 4423. This is a serious, powerful groundswell that will be reeling. For a spot like this, that long period is going to make it very clean and powerful, so it's one for the experienced crew.
The following Monday, August 31st, also has a clean 6ft SSW swell with light offshore winds, keeping the quality high. The first week of September continues to show potential, but the wind gets a bit tricky. The standout then is Tuesday, September 8th. After a few days of dangerously big, unsurfable swell, the morning shows a clean 10ft SSW groundswell with a light offshore wind. The energy is high at 4088, and it’s rated excellent for experienced surfers. A great way to wrap up the forecast.
So, to boil it down: Wednesday the 26th and Sunday the 30th of August are your best bets. The 26th has that classic, clean, manageable size, and the 30th offers a bigger, more powerful swell. The second week is a bit more of a gamble, but the 8th of September is another promising one if you can wait it out. The water temperature is about average for the time of year.
Stay safe and get amongst it.

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.

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.
