The Lowdown
G’day, it’s Rusty here. Let’s have a look at the next few weeks for Fourth Beach. The water temp is sitting at 61.3°F – right on the money for this time of year, no weirdness there.
The first part of the window has serious grunt, but it’s just too much of a good thing for this spot. We’ve got a meaty 13.1ft groundswell from the SSW with a long 16-second period rolling in on Wednesday morning, the 12th of August. The combined swell energy is pumping at 7406 (moderate-strong), but honestly, it’s a fair step above what a beach break like this can handle comfortably. Wind is cross from the west at 12 mph – not ideal, with a bit of chop. The afternoon stays similar, just a touch lighter. Not the day to paddle out unless you’re a proper charger and even then, it’s pushing it.
Thursday the 13th sees the swell drop a fraction to 11.5ft, still from the SSW with that nice long period of 16 seconds. The morning has a light WNW breeze going cross-off, which cleans things up nicely – but again, it’s big and powerful (combined energy 6369). The afternoon swings onshore from the SSE, which kills the quality. Still too large for most.
Friday the 14th of August – now we’re talking. Swell eases to 9.8ft from the SSW, still a good 16-second period. The highlight is the wind: light NNE in the morning going cross-off, swinging to a light easterly cross-off in the afternoon. Both sessions are clean. The energy is still big at 4665 but now it’s in the wheelhouse for experienced surfers. This is the first real standout. The crowd factor is listed as “sometimes” so you might have some company, but that’s the price of a good one.
Saturday the 15th of August morning is another good option. Swell has dropped to 7.2ft from the SSW with a 14-second period. Combined energy at 1987 is moderate. What makes it a winner is the moderate offshore NNE wind at 12 mph – clean, lined-up waves. This is the best on offer for the first week. The afternoon gets a bit messy with a cross-onshore ESE breeze, so make the most of the morning.
Sunday the 16th has a clean morning with NNE cross-off wind, but the swell drops to 4.3ft and the energy is low at 1295. It’s rideable but not a standout. Afternoon gets a cross-shore wind and a bit of chop.
Monday the 17th kicks up a fresh swell at 5.9ft from the SW, with a very long 19-second period. The morning wind is a strong offshore NNE at 28 mph – super clean faces, but paddling into that long-period groundswell with that wind will be a battle. Only for the fit and experienced. The afternoon eases to 22 mph and goes cross-off. Still clean but that wind is strong.
The middle of the week from Tuesday the 18th through Thursday the 20th is mostly messy or too small. Tuesday has lumpy cross-shore wind and rain, Wednesday morning looks cleaner with fresh offshore, and Wednesday afternoon the 19th actually cleans right up – gentle offshore NNW, 5.6ft swell from the SSW with a 15-second period (energy 1423) – that’s a sneaky fun session for experienced crew. Tuesday the 25th of August morning stands out: light north wind going offshore, 8.2ft swell from the SSW at 14 seconds, and combined energy of 4923 – solid, powerful, and clean. That’s another one to mark.
Thursday the 20th of August we get a jump back up to 13.1ft from the SW with a short 13-second period – combined energy is huge at 9865 – but the wind is cross-off and clean. Still, that’s expert-only territory. Afternoon eases to 9.8ft and becomes more manageable with light ENE wind – cleaner, but still big.
Friday the 21st is a write-off – strong cross-onshore wind and rain, messy as anything.
Saturday the 22nd sees another pulse: morning is 11.5ft from the SW with a massive 21-second period and energy at 9486 – way too big and long for a beach break. Afternoon jumps to 16.4ft from the SSW – that’s knit-your-own. Not the place.
Sunday the 23rd morning still has 13.1ft but short period at 10 seconds, so it’s lumpy and ugly despite clean wind. The afternoon drops to 7.9ft from the SW at 14 seconds and clean cross-off – that’s a better bet.
Monday the 24th is onshore and choppy, and Tuesday the 25th morning is that good one I mentioned earlier – the standout of the second week.

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.
