The Lowdown
G’day, Rusty here, lookin’ at the next 16 days for Fourth Beach. It’s a tricky outlook, mate. The big news is a massive pulse of west to south-west swell that’s gonna hammer the place, but the wind is gonna be a battle for most of it. There’s a short window early on that’s the pick, and then a couple of later sessions that are worth a look if you’re a seasoned local. The water temp is about average for this time of year, so a standard spring wetsuit will do.
Friday the 4th is a write-off. We’re talkin’ a brutal 13ft to 16ft of SW swell with a 31 mph cross-wind. The combined swell energy is a wild 6693 to 7405, but it’s ugly, messy, and dangerous. Don’t even think about it. Saturday the 5th morning is your one true standout. The swell drops to a still-solid 10ft from the SSW (3451 energy), but the wind swings around to a light north-westerly, giving us a clean, cross-off breeze. The sets will have some serious length on them, with a 14-second period, so expect lots of power and long, walling rides. This is for experienced surfers only – it’s too big for beginners. The afternoon gets a bit iffy as the wind turns light cross-onshore, dropping the swell to 8ft.
Sunday the 6th through to Tuesday the 10th is a long, disappointing stretch. The wind is a dog – onshore, cross-onshore, and strong – with lumpy, choppy conditions. The swell hangs around 10ft to 13ft with a mix of periods, but the poor wind quality ruins it. Combined energies are high, like 3801 to 7962, but it’s all just a messy, dangerous paddle. There’s a brief flicker on Thursday the 11th morning with a 5ft SSW swell (1338 energy) and a clean cross-off breeze, but it’s marginal and small.
The next real chance comes on Saturday the 12th afternoon. The wind fades to a moderate WNW cross-off, and the swell kicks back up to a solid 10ft from the SW with a 16-second period (4666 energy). The waves will be clean and powerful, but at 10ft it’s still only for the experienced crew. The morning of that day is a small 4ft SW swell (959 energy) with a fresh offshore wind, which is clean but tiny.
The second week is a bit of a lottery. From Sunday the 13th to Monday the 14th, the wind is back onshore and messy with strong cross-swells, so no good. Tuesday the 15th morning is a strange one – a huge 12ft SSW swell (7344 energy) with 18-second period, but it’s flagged as being too big for this break. The wind is light, but the sheer size makes it a big-wave mission for absolute experts only. Wednesday the 16th afternoon is similar, with a massive 15ft SSW swell (11972 energy) and 17-second period, again too big for most.
The last chance is Friday the 18th morning. Finally, a clean forecast! A gentle north-northwest offshore wind, a 7ft SSW swell (1756 energy) with a 13-second period. That’s a good, clean, powerful wave for experienced surfers, and it’s the best call in the second week. The morning of Saturday the 19th also has a huge 12ft SSW swell (11024 energy) with a 19-second period, but it’s once again flagged as too big for the break.
So, the pick is Saturday the 5th morning. That’s your clean, powerful, long-period swell with a glassy feel. After that, keep an eye on Saturday the 12th afternoon and Friday the 18th morning for a clean session, but don’t expect the same quality. The rest is a battle with the wind or just too much size.
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. 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.
