The Lowdown
Alright, let’s get into it. The ocean’s been working, and there’s a solid window of surf ahead, but you gotta pick your moments. This stretch is all about conditions, not just size. The water’s sitting at 62°F at Fourth Beach, which is right on the money for this time of year, nothing weird going on there.
We start Wednesday morning with a clean 7ft SW groundswell rolling in at 16 seconds. That’s proper energy, with a combined energy of 2201, and a light WNW cross-off breeze keeping things tidy. It’s gonna be a fun one for the experienced crew – the period is long, so be ready for those lines to push through. The afternoon jumps to 10ft and the energy jumps right along with it to 4258, but the wind swings south and onshore, so it’ll get a bit lumpy. Not the pick.
Thursday is where it starts to get interesting. The morning has that same 10ft SSW swell, but now the wind is a gentle offshore from the north. The energy is still pumping at 4021, and the surf is clean. This is a proper morning session. The afternoon drops a touch to 8ft, but stays clean with that same offshore wind, and the energy is still strong at 3543. Thursday is a solid day.
Friday brings a bit of rain, but the swell holds at 10ft. The morning has a cross-off breeze, but the afternoon looks better with lighter WNW winds and a 5/10 call. The energy is still up there, over 4000. It’ll be worth a look if you can dodge the showers.
Then things get wild. Saturday the wind goes full gale from the WSW at 31 mph, and the swell jumps to 13ft, then 15ft. The energy readings are massive – 6359 and 8876 – but it’s blown out. Forget it. Sunday is even bigger, with a 16ft swell and a huge energy reading of 20447. The wind is cross, and the call is that it’s just too big for this break. Same story Monday and Tuesday – the swell is massive, the wind is on it, and it’s a washing machine. This is not a paddle-out situation; honestly, this setup looks more interesting for kite surfing than anything else.
The size finally starts to back off mid-week, but it’s still big. Wednesday the 12th has 13ft with a cross-off breeze in the morning, but it’s still over the top for this spot. Thursday the 13th has that same 13ft, but with a clean offshore wind in the morning – still too big, though. The energy is over 10,000, so it’s powerful, but it’s not what you want here.
Friday the 14th is the one. The swell drops to a more manageable 12ft, and you have a clean, gentle offshore wind all day. The energy is still substantial at 7462 in the morning, but it’s clean and the wave comment says it’s favorable. The afternoon is even better with a slight cross-off and energy around 6124. This is the standout of the whole run – a proper, powerful swell with clean conditions.
The weekend after that settles down a lot. Saturday the 15th sees the swell drop to 7ft, but the winds are a bit all over the place. Sunday the 16th is the one to watch – the morning is glassy with a 7ft SSW swell and a 15-second period. The energy is lower at 1762, but it’s clean and fun. That’s a great pick for a relaxed session.
The following week starts off a bit choppy again. Monday the 17th has cross-onshore winds, and Tuesday is similar. The swell is still in the 6-10ft range, but the quality drops. Wednesday the 19th has a cross-off breeze in the morning, and the afternoon looks clean with an 8ft swell and offshore winds. That’s a decent end to the run before the wind goes wild again on Thursday the 20th with a near gale.
So, the long and short of it: the first few days are fun, but the real standout is Friday the 14th – big, clean swell with offshore winds. After the huge, blown-out weekend, Sunday the 16th is your next best bet for a clean, smaller wave. The second week is more about picking the calm windows; it’s not as consistent.

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.
