The Lowdown
Alright folks, Rusty here. Let’s get into it.
We’ve got a bit of a slow start on the cards, but there’s a glimmer of something worth paddling out for later in the window. The first proper swell arrives on Saturday the 5th, but it’s a bit of a messy one. Fourth Beach is an advanced break, so you’ll need your wits about you. The water’s sitting at 62.2°F – pretty much average for this time of year, so no nasty surprises there.
Saturday 5th (afternoon) – There’s an 8.2ft swell pushing in from the SSW, but that solid 14-second period tells us it’s a groundswell with some real grunt. The combined energy is pumping at 3494 (moderate to strong). Problem is, the wind is a light onshore breeze from the SSE. It’s not ruining it outright, but it’s not ideal. The report flags questionable tide conditions, so it’s a gamble. Not a standout.
Sunday 6th – The swell drops to 4.3ft in the morning, but the wind swings onshore and picks up to 12 mph. By the afternoon it’s a fresh 19 mph cross-onshore making a lumpy mess of things. Sunday is a write-off.
Monday 7th to Tuesday 8th – This is where it gets big but ugly. Swell jumps to 9.8ft with a very long 17-second period, and combined energy is through the roof (5108 to 5589). That’s serious power. But the wind is a moderate to fresh cross-onshore all day, making it choppy and lumpy. At 9.8ft and over 8.2ft, this is strictly for experts only, and even then, the conditions are poor. Kite surfers might be having a field day, but for paddle surfing, it’s a hard pass.
Wednesday 9th through Thursday 10th – The swell drops a touch (4.9ft to 8.2ft) and the wind shifts to a cross-offshore (NE/ENE), cleaning things up nicely. The combined energy is still moderate (1084 to 2999). These afternoons are the most promising in the first week—clean faces, decent shape. The 4.9ft to 5.9ft on Thursday afternoon is a nice size, and the wind is gentle. Worth a look if you’re keen, but not a true standout.
Friday 11th (afternoon) – Here’s the first real highlight. The swell is 3.9ft from the SW, combined energy at 990 (moderate), but the wind is a gentle cross-offshore from the NNW, and the report says “expect very good surf conditions.” That’s a clean, fun-sized wave. The period is 14 seconds, so it’s a proper groundswell. This is a solid window for a session.
Saturday 12th to Sunday 13th – A bit of a mixed bag. Saturday afternoon sees the wind back onshore, making it messy. Sunday morning has a clean cross-offshore, but the swell drops to 5.2ft with a shorter 11-second period (combined energy 897). Then Sunday afternoon gets hammered by a strong breeze from the SW, bringing rain and mess. Skip it.
Monday 14th – Another big, clean-ish morning. 9.8ft from the SSW with a 15-second period, combined energy 3745. The wind is a light onshore from the SSE, so it’s not glassy, but it’s manageable. The report says “marginal,” but with light wind, it’s a possibility for the brave. By the afternoon, the wind picks up and ruins it.
Tuesday 15th (morning) – THIS IS THE STANDOUT. The swell is 6.9ft from the SSW, period 14 seconds, combined energy 1878 (moderate). The wind is a moderate offshore breeze from the north, keeping it clean. The report calls it “excellent surf conditions for experienced surfers.” This is the best wave of the forecast period. Get out there if you can.
Wednesday 16th onwards – Things get messy again. Swell stays around 6.6ft to 7.2ft, but the wind is cross-onshore, making it choppy. Thursday the 17th sees the swell drop to 4.3ft with weak energy (682) and poor wind. Friday the 18th has a clean cross-offshore but the swell is 6.9ft with a shorter 13-second period, and the wind is fresh (22 mph). Not great.
Saturday 19th to Sunday 20th – The swell builds big again (9.8ft to 13.1ft), with combined energy maxing out at 7734 on Saturday afternoon. That’s very strong, but the wind is cross-onshore and messy. Sunday the 20th morning has an 11.5ft SSW swell (5096 energy) but the wind is a moderate cross-shore. The report says it’s predicted to be too big for this break. Honestly, unless you’re a pro with a death wish, give it a miss.

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.
