The Lowdown
Alright, folks, let’s get into it. This stretch is a slow burner at Fourth Beach. We’ve got some solid swell potential, but the timing and conditions are gonna be the big talking points here. It’s a one-break forecast for this zone, so get ready for a couple of standout windows, but also some real rough patches to sit out.
Things kick off Friday the 28th of August, and honestly, it’s a write-off. We’ve got a 5ft SW swell but it’s getting hammered by a 19 mph SE wind. The water’s all lumpy and cross-onshore. It stays ugly through Saturday too, with a big, drawn-out 21-second groundswell, but those cross-shore winds are keeping it messy. You’re better off waiting.
Alright, here’s the first real nod. Sunday the 30th of August is your pick for the first week. We’ve got a solid 8ft SSW groundswell (18 seconds), clean conditions with a light ENE breeze, and it’s glassing off. The wave energy is very strong (4533). This is going to be proper for experienced surfers. It’s a bit overhead, so the beginners should sit this one out. The winds are light and cross-offshore, keeping things clean. This is the best on offer in the first week. Crowds are possible, so don’t expect it to be empty.
Monday the 31st has some fresh offshore winds from the N, but the swell drops to 7ft and the conditions are more marginal. Tuesday and Wednesday look bumpy with cross-onshore winds and a messy 7-8ft swell. We’ve got some moderate wave energy in the 1500-2600 range, but it’s just not clean.
Now, hold onto your board. Thursday the 3rd of September sees a big jump. We’re looking at an 12ft SSW swell, but for an advanced break like Fourth Beach, this is pushing past the fun zone and into "too big" territory. The forecast says it’s too big for this break, so this is for very good, confident surfers only. The winds are WNW and clean in the morning, but that size is a major factor. Wave energy is extreme (8221).
Friday the 4th falls apart again with onshore winds and lumpy 10ft waves. The next good opportunity pops up on Saturday the 5th of September. A 8ft SSW swell arrives with glassy morning conditions from a NNE breeze. That's a nice, clean, manageable size for advanced paddlers, and the wave energy is strong (2151). Sunday the 6th has a brief window of glassy conditions early with a 6ft SSW swell, but the onshore wind kicks in by the afternoon.
The following week starts off clean but smaller. Monday the 7th sees a 4ft SSW swell with gentle offshore winds, making for some clean, smaller waves. By Tuesday the 8th, the wind picks up again. Big dumps show up on Wednesday the 9th and Thursday the 10th, with forecasted swell up to 18ft and insane energy levels (over 15,000). This is for properly experienced big-wave chargers only. The rest of the run looks bumpy.
The standout window is clear: Sunday the 30th of August for the big clean groundswell, and Saturday the 5th of September for a slightly more manageable, clean morning session. The rest is a mix of onshore winds or swell that’s just way too big.

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.
