The Lowdown
Alright, Rusty here. Let’s break down what’s coming at Fourth Beach over the next couple of weeks.
We’ve got a decent run of surf on the horizon, but it’s not all clean. Water temp is about 62°F, pretty normal for this time of year. Nothing worth paddling out for on Thursday the 19th—the wind’s onshore and the surf is poor.
Friday the 21st is a real standout. 8ft SW groundswell with a long 15-second period, and the wind is glassy out of the ENE. That’s a dream scenario for experienced surfers. The wave energy is strong (3384), so there’s plenty of juice, but that long period might make the waves a bit straight at a beach break. Expect some company in the water.
Saturday the 22nd is another good one. 7ft SSW swell with a 14-second period, clean offshore winds from the north, and strong energy (2884). It’s going to be clean and fun, but again, watch for the longer period making things a little fat.
Sunday the 23rd and Monday the 24th are messy with cross-onshore wind and chop. Skip ’em. Tuesday the 25th is small—5ft and 4ft—with the energy dropping to moderate (742 and 625), but the winds are clean and cross-offshore. Good for a small-wave cruise.
Then we get a big one on Wednesday the 26th. 10ft SW swell with a very long 17-second period. That’s huge energy (7817). The wind is cross-onshore from the SSE, so it’ll be lumpy. Experts only at this size.
The end of August and start of September clean up nicely. Sunday the 30th and Monday the 31st both offer 5ft to 6ft SSW swells with 17 to 18-second periods, light offshore or cross-off winds, and clean conditions. Strong energy (1625 and 1646). Excellent options for experienced surfers.
Tuesday the 1st of September finishes strong—5ft SW swell, 15-second period, offshore winds in the morning, light cross-off in the afternoon. Moderate energy (1204 and 1103). A good, clean start to the month.
Best bets: Friday the 21st and Saturday the 22nd are your top picks. Glassy conditions, strong swell, and clean faces. Get out there.
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.
