The Lowdown
Alright, Rusty here, let's look at what's on the table.
Right now, things are a bit of a mixed bag. We've got swell coming through, but the wind is messing it up for most of the first week. The real standout is gonna take some patience to get to.
We’re starting off on Sunday the 13th. The swell is there at Fourth Beach, pushing about 5ft from the SW with a solid 14-second period, and the energy is strong (1364). But the wind is on it, blowing 9 mph from the south, and it’s just not clean. You’d be fighting a bumpy surface.
Monday the 14th looks pretty ordinary. The swell builds, hitting 7ft on Monday morning and then a chunky 10ft in the afternoon from the SSW, with periods of 13 to 15 seconds. The energy jumps up (2292 and 3258), but the wind is a cross-onshore mess, 12 to 19 mph. That’s choppy, lumpy, and not worth your time.
Tuesday the 15th is a bit better. The wind swings to a cross-offshore from the ENE at 19 mph in the morning, cleaning things up on that 8ft, 14-second SSW swell (2164 energy). It’s a "clean" call, but it's still a fresh breeze, so it won't be perfect glass. The afternoon gets choppy again.
Wednesday the 16th morning could be your first decent window. The swell is 6ft from the SSW, 14-second period, with a cross-offshore breeze from the ENE at 16 mph (2309 energy). The forecast calls it clean. It's still a moderate breeze, but it's the best morning of the early week.
Thursday the 17th is a tease. The swell drops to 4ft, but the wind goes offshore from the north, 19 mph in the morning, dropping to 12 mph in the afternoon. The afternoon session is called "good surf conditions" with moderate offshore wind and clean lines. The energy is low (508), but the quality might make up for it. Worth a look for a clean, small-wave session.
Friday the 18th morning is similar—clean with a light cross-offshore breeze, but the swell is still only 4ft (636 energy).
Now, the first real standout is shaping up for Sunday the 20th. This is the one to circle. Early morning, we’ve got 10ft of clean SSW groundswell, with a 13-second period and light offshore winds from the ENE at just 6 mph. The energy is pumping (2588), and the conditions are called "excellent for experienced surfers." This is big swell—over 8ft—so it’s strictly for the experts. For the advanced crew, this is the pick of the first week.
The following week has some huge numbers, but they come with big caveats. Saturday the 26th morning shows a massive 15ft SSW groundswell with a very long 19-second period. The energy is insane (18881). The wind is light and cross-offshore. But the forecast itself says it’s too big for this break. This is a "look but don't touch" situation unless you’re on a big-wave gun and know exactly what you're doing. Same goes for Sunday the 27th morning with 12ft (5299 energy) and clean winds—still too big for the average punter.
After that, we settle back down. Monday the 28th morning brings a 7ft swell from the SSW with a fresh 22 mph offshore wind from the north, cleaning it up (1719 energy). It’s another clean, punchy option for the advanced surfer.
So, to sum it up: the first few days are frustrating with the wind. The standout for the whole run is the morning of Sunday the 20th at Fourth Beach—big, clean, and powerful for those who can handle it. The weekend after that has massive, dangerous swell. Keep an eye on the Thursday and Friday mornings for smaller, cleaner windows if the big stuff isn't your game.
The water temp is sitting at 61°, which is about average for this time of year, nothing unusual there.
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.
