The Lowdown
Right then, let’s have a look at what’s on offer. We’ve got a solid run of swell coming in, but it’s not all smooth sailing. The water temp is sitting at 61°, which is bang on average for this time of year, so no surprises there.
The main story is a big, long-period groundswell from the SSW that’s gonna be pumping through. The energy is massive, hitting 4340 (strong to very strong wave energy) on Friday afternoon the 14th, with a 10ft swell. That’s some serious size. The wind is a cross-shore from the ESE at 12 mph, which will put a bit of a chop on it, so it’s not going to be perfect. This is definitely advanced territory at that size.
Saturday morning the 15th looks a lot cleaner. The swell drops to 7ft from the SSW, with a lovely cross-off breeze from the NNE at 9 mph. Clean faces. The energy is still strong at 1874 (moderate wave energy). This is a solid option for the experienced crew.
The real standouts, the ones you’d circle on the calendar, are the Monday morning on the 17th and the Thursday morning on the 20th. On the 17th, we’ve got a 6ft SSW swell with a 19-second period – that’s very long period groundswell, so it’ll have heaps of punch and long lulls between sets. The wind is a fresh offshore from the N at 19 mph, making for clean, groomed waves. The energy is 2573 (strong wave energy). On the 20th, the swell jumps back up to 10ft from the SW, 16-second period, and the wind is a whisper-light WNW at 3 mph, almost glassy. The energy is 3794 (strong to very strong wave energy). That’s a big, clean day for experts only.
There’s a bit of a rough patch from the 18th to the 19th, with strong onshore winds and lumpy conditions, so you’ll want to sit that out.
Then, the forecast gets really interesting for the 23rd. Sunday afternoon on the 23rd, we’ve got a 10ft SSW swell, 17-second period, and a gentle cross-off breeze from the NNE at 9 mph. The energy is 4812 (strong to very strong wave energy). This is a fantastic, clean groundswell. It’s a long way out, so treat it as promising but not locked in.
Later on, the 26th of August offers a real treat for the morning session: a glassy 8ft SSW swell. The wind is from the SW at only 3 mph, making it dead flat. That’s beautiful. And the 29th is looking excellent too, with a 7ft SW swell, 18-second period, and a clean offshore wind from the NNW at 16 mph. The energy is 2974 (strong wave energy). That’s another one for the experienced surfer to get excited about.
Fourth Beach is a fairly exposed beach, so it gets the swell, but it can get a bit straight with these long-period swells. It’s a consistent break, but be aware that crowds are possible here.
If you’re not a strong paddler, be careful with anything over 8ft – that’s expert territory. The 4ft to 7ft swells with clean winds are your best bet for a fun, manageable session.

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.
