The Lowdown

Righto, let’s have a look at what’s on the cards. We’ve got a solid run of swell on the way for Fourth Beach, and the first real taste of it hits early on Friday. The water temp is sitting right on average for this time of year at 61°, so nothing out of the ordinary there.

Friday morning, August 21 – this is the standout. Glassy conditions, clean as a whistle, with a solid 8 ft SSW swell rolling in at a generous 15 seconds. The combined energy is pumping at 3384, which is strong and full of grunt. This is proper groundswell, and with that long period, it’ll be best handled by experienced surfers – it’s over 8 ft, so experts only. The offshore wind is nil, making it glassy perfection. Crowds can be an issue here sometimes, so get in early.

Friday afternoon the wind swings SE and it gets a bit choppy, not worth your time.

Saturday morning, August 22 is another good shout. A clean 7 ft SSW swell with a 12 mph north wind blowing offshore. The energy is still strong at 2997, and it’s clean. Still sizey for a learner, but good fun for intermediates and up.

Saturday afternoon picks up a touch to 8 ft, but the SE cross-onshore breeze puts a bit of texture on it.

Sunday looks messy – onshore winds and dropping energy, best to give it a miss.

Monday, August 24 sees a return of 8 ft SSW swell at 15 seconds, but it’s got a cross-onshore wind, making it choppy. Not the best for a clean wave.

Tuesday, August 25 drops down to 5 ft, but the wind is cross-offshore and clean in the morning. A smaller, cleaner option if you want a paddle.

Wednesday morning, August 26 is a real highlight. 7 ft SW swell, 15 seconds, with a 9 mph north offshore wind – clean and punchy. Energy is strong at 2565. This is another one for the experienced crew, with great shape on offer. Wednesday afternoon, however, gets messy with onshore wind and a big 10 ft spike, but it’s blown out.

Thursday, August 27 is a write-off – strong onshore winds and lumpy, dangerous conditions.

Friday, August 28 stays poor with onshore wind and dropping swell.

Saturday, August 29 is small and blown out.

Sunday morning, August 30 – a nice surprise. 7 ft SSW at 16 seconds, clean offshore cross-off wind, and the energy is strong at 2147. This is a gem for experienced surfers, with long-period groundswell and clean faces. Crowds possible.

Monday, August 31 holds 7 ft SSW at a very long 17 seconds. Morning has a fresh offshore wind, and afternoon is clean too. Energy is high at 2964. Great for the experts, and the long period will make it wall up nicely at the point.

Tuesday, September 1 has smaller 6 ft glassy conditions in the afternoon – a good option for a cruisier session.

Thursday, September 3 is blown out again.

Friday, September 4 sees a return of size: 8 ft SSW at 17 seconds, with clean cross-offshore winds. Energy is huge at 4304. This is another standout for experienced surfers only – powerful, long-period groundswell with clean conditions.

Saturday, September 5 drops off with onshore wind and lumpy conditions.

All in all, the best bet is Friday morning, August 21 – it’s as good as it gets: glassy, strong, and well-formed. Sunday morning, August 30 and Monday morning, August 31 are also top-tier for the experienced crew.

Stay safe out there.

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.
