The Lowdown
Right, mate, Rusty here. Let’s talk about what’s on the menu for the next little while at Fourth Beach.
It’s a pretty bleak start, to be honest. There’s a solid 4ft SSW swell in the water on Sunday the 6th, with a period of 13 seconds, but the wind is just howling straight onshore. The combined energy sits at 849 (weak), but the chop is going to be a mess. That’s a no-go. We’ve got a long stretch of poor to marginal conditions right through the start of the week. The swell actually builds to a proper 10ft on Monday the 7th, period hitting 17 seconds, and the energy jumps to 5135 (strong), but it’s all cross-onshore, making it lumpy and ugly. This continues into Tuesday the 8th with 10ft swell and 35 km/h cross-onshore winds – that’s more of a kite session than a paddle-in wave.
We finally get a shift on Thursday the 10th. The swell drops back to 5ft, period 14 seconds, and the wind turns clean cross-off. The energy is 1043 (moderate). It’s still only marginal, but it’s a step in the right direction. The real standout, though, is going to be Friday morning the 11th. The wind goes light offshore from the North at 20 km/h, and that 4ft SSW swell (15-second period, 1067 energy) is going to be clean and lined up. It’s described as “very good surf conditions,” and that’s the first real window we’ve had. The water temp is sitting at 62°, which is about normal for this time of year, so no surprises there.
The next big opportunity fires up on Monday the 14th. Morning brings a glassy 8ft SSW swell with a 16-second period, and the energy is a solid 3415 (strong). This is labelled as excellent for experienced surfers, and it’s one of the best on the table. The water is dead calm, so that wave is going to be a proper groundswell, peeling cleanly. Just be aware, with an 8ft swell, that’s getting into expert-only territory.
Looking further out, Saturday the 19th sees a massive 12ft to 13ft SW swell, with an 18-second period and energy readings of 7759 and 5808 (very strong). The wind is clean cross-off, but the forecast is clear: the swell is too big for this break. The same goes for Monday the 21st with another 12ft monster. However, Sunday the 20th morning offers a much more manageable 7ft SSW swell, period 13 seconds, with 3013 energy and light cross-off winds. That’s going to be a good one, cleaner and more accessible.
For the best on offer: I’d say Friday the 11th morning for the clean, offshore lines with the 4ft swell, and Monday the 14th morning for the bigger, more powerful groundswell that’s glassy. These are the true standouts. The rest of the period is a mix of marginal conditions and oversized swells, so pick your moments.
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.
