The Lowdown
Alright, surfers, Rusty here. Let's look at the run ahead at Fourth Beach.
It’s a bit of a tough start, honestly. We’ve got a decent sized SW groundswell rolling in over the next few days, but the wind is going to mess it up. Saturday the 12th has a solid 5ft SW swell with a very long 17-second period, giving us some serious energy, but that 28 mph W wind is going to put a lot of chop on it. Sunday the 13th is a mess of cross-shore winds, and then Monday the 14th is a write-off with stormy conditions as the swell jumps. The water temp is 62°F, which is pretty average for now.
The first real window shows up on Tuesday morning the 15th. The wind will swing around to an ENE cross-offshore, cleaning up a solid 8ft SSW swell. That’s a bit heavy for beginners, but the conditions should be workable for the experienced crew. Wednesday the 16th and Thursday the 17th also look promising with lighter winds and clean conditions on a dropping swell, running from 6ft down to 4ft.
Then it gets wild again. Friday the 18th has gale-force cross-winds that'll trash it. The following Saturday and Monday have huge, windy, and lumpy swells.
But the standout is the morning of Sunday, September 20th. This is the one to circle on the calendar. The wind is forecast to be totally glassy, and we’ll have a 10ft SSW groundswell with a nice 13-second period. This is for experienced surfers only – it’s going to be powerful and clean. Expect crowds though, as it’s a sometimes busy spot. The surf break is fairly exposed to the SW, which is right in the optimum direction for this spot.
The run looks like it’ll finish big, too. The morning of Friday, September 25th offers another clean window with a WNW cross-off breeze and another big 10ft SSW swell. Again, this is expert territory.
A big heads up: the 24th and 27th of September have massive swells over 13ft with extreme energy levels, but the break itself is predicted to be too big to handle, even for experts.
Overall, the setup has more misses than hits, but the mornings of the 15th, 20th, and 25th are the real gems if you can pick your window. Stay sharp.
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.

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.
