The Lowdown
Alright, grab a coffee, 'cause we got a proper forecast on our hands for Fourth Beach over the next couple of weeks. It's not gonna be a straight-forward run, with some proper boomers early on and a lot of waiting around for the wind to play nice. Let's get into it.
The first real movement shows up overnight tonight, with a solid SSW swell filling in. Sunday morning (the 10th) is looking at 10ft of swell with a 15-second period, and the energy reading is a solid 3316. The wind is cross-offshore, which should keep the face reasonably clean. It’s a bit of a challenge, but it's a start. It’s not an all-time day, but there are waves.
Then, get ready because the ocean is about to roar to life for the start of the new week. The swell just explodes on Tuesday the 12th. We’re talking 18ft of SSW groundswell with a 16-second pulse, and the energy is massive at 24663. That’s not just a step up; that's a full-on jump. The problem is the wind is a fresh cross-onshore, making it lumpy as all hell. It’ll be wild and powerful, but the surface will be a mess. This is not a day for the faint of heart; honestly, it looks like a day more suited for kite surfing than paddle surfing. The swell stays well overhead for the next few days, with Wednesday and Thursday still holding 11-12ft, but the wind stays stubbornly cross-shore or cross-on. The energy is still considerable, sitting in the 5000-6000 range. The keyword for this stretch is "messy."
We get a break in the clouds and the wind on Friday the 15th. The swell eases to a still-chunky 10ft, but the wind goes light and cross-offshore from the ENE. The energy is still moderate at 4396. This is the first real standout window. It’s still big, but clean, powerful, and lined up. This will be one for experienced surfers only, as the size is going to be pushing double overhead plus. The following days ease off a touch, with Saturday showing 6-7ft and Sunday dropping to 4-5ft, but the winds are a mix of cross-off and offshore, making for clean conditions. These are more manageable days for a broader crew.
Keep an eye on the 17th. The swell drops to 5ft but the period is a very long 19 seconds, and it's a clean offshore wind day. That’s a proper, long-period groundswell, and the energy, while lower at 2585, is still decent. That long period might make it a bit straight at a beach break, but the conditions should be pristine.
After the weekend, the week of the 18th continues to play nice. Tuesday the 19th is looking prime, with 8ft of SSW swell, and by the afternoon the wind goes completely glassy and the swell settles to 8ft. That’s going to be a magic session, with the surface like a lake. The swell direction is a consistent SSW, matching what this spot wants. As we get into the second week, the 20th and 21st still have some fun waves around 6-8ft but the winds get a bit more variable, a lot of it cross-off or light cross-shore. It’s not going to be as perfect as Tuesday, but there are still waves to be had.
Then the ocean gets angry again on the 23rd, with onshore winds and a jump in swell back to 11ft, making for poor conditions. The following days (the 24th and 25th) see the swell stay around 10ft but the wind shifts offshore or cross-off, cleaning it up once more. This is the final stretch of the forecast, and it looks similar to the first week: big, powerful surf, but you’ll have to pick your moments when the wind lets it get clean.
Looking at the whole window, the standout swell for pure power is that Tuesday on the 12th, but the wind ruins the party. If you want clean, quality surf, you have to wait for the brief windows like Friday the 15th and especially Tuesday afternoon the 19th, where the combination of a solid swell and glassy conditions will make it unforgettable. The water temp is 62°, which is about average for this time of year, so a decent 3/2 is your friend. The later half of the week and into the next week has some promising but less certain conditions. It's not a classic two-week run, but when it's on, it will be seriously good.

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.
