The Lowdown
Alright, this is Rusty talking. Let’s look at what Fourth Beach has cookin’ for the next couple of weeks.
The overall vibe is a solid run of groundswell, but a lot of wind and size to work around. The early part of the week is a struggle, but we have a couple of windows that’ll get you out of bed, especially for the more experienced surfers.
We start the forecast period on Monday the 14th with a decent push of swell at 7ft from the SSW, with a period of 13 seconds giving it a moderate wave energy (2292). Problem is, the wind is a cross-on SSE breeze at 12 mph, making it choppy. Not a great start. That swell builds through the afternoon to 8ft, but with a fresh SE cross-onshore wind at 19 mph, it’s going to be lumpy and poor. This one’s a write-off.
Tuesday the 15th: The swell drops a touch to 8ft, still from the SSW. Morning winds are from the ENE at 16 mph, keeping it cross-off, which cleans it up a bit. Still marginal, but cleaner than Monday. The afternoon turns cross-shore and lumpy with a fresh E breeze.
Wednesday the 16th is where it starts to look a bit better. We have 6ft of SSW groundswell with a clean-looking morning under clear skies and a moderate NE cross-off breeze at 16 mph. The wave energy is still solid (1691). It’s a marginal call, but the cleanest we’ve seen so far. The afternoon stays clean but the swell eases to 5ft.
Now, the first real standout appears on Sunday the 20th. After a messy Saturday with a big 12ft SW swell and strong cross-winds that are no good for surfing, Sunday morning delivers a clean 7ft SSW groundswell. The key here is the light WNW cross-off breeze at only 6 mph. This is clean, excellent surf for experienced surfers. The energy is pumping at 2355. This is the one to circle.
We then have a few more days of mixed conditions. Monday the 21st has an 8ft SSW groundswell but the wind is on it, making it cross-shore. Tuesday the 22nd is similar, with fresh cross-winds. The long-range looks like it will build again, but it comes with a major caveat.
The second real standout is on Friday the 25th. Another excellent morning. The swell is a clean 8ft from the SSW, with an extra long period of 16 seconds. This is proper groundswell. The wind is glassy – dead calm from the east at just 3 mph. This is incredible for a break like this. The wave energy is massive (3374), but that 8ft is pushing the limit. This is for the experts. The afternoon then goes to 12ft and cross-onshore, which will be too big and messy.
Following that, Saturday the 26th is for big-wave chargers only, with a huge 13ft SSW swell at an 18-second period. This is very strong energy (11610), but it’s way too big for a regular paddle session. Stick to early Friday for your best shot.
So, to sum it up: there are two clear standouts. For the best combo of size, period, and glassy conditions, get on Friday morning the 25th. For the best clean swell earlier on, go for Sunday morning the 20th. Both are for intermediate to expert surfers due to the size. Crowds are a possibility here, so get in early.
Stay frothy.
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.

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.
