Alright, Rusty here. Let’s talk about what’s coming our way.
The next couple of weeks are looking pretty lively for the exposed reef at Flatrock. There’s a bit of a wait for the first good session, but once it gets going, there’s some serious energy on the cards. The water temp is sitting at about 60° right now, which is pretty much what you’d expect for this time of year.
The action kicks off on Sunday the 5th. It’s not for the faint-hearted – we’ve got a solid 12ft SSW swell rolling in with a very long 17-second period. That’s a heap of groundswell energy (6602), and with a clean, moderate offshore breeze from the east, it’ll be holding up nicely. This is expert-only territory, though. The swell drops a touch in the afternoon to 10ft, but it’s still clean and powerful.
Monday the 6th is a step down in size but still a good one. You’ve got 6ft SSW swell early, period dropping to 14 seconds, and a light offshore breeze. The energy is still moderate (1504) and conditions are clean. By the afternoon, it’s a bit smaller at 5ft but still lined up and rideable.
Tuesday the 7th brings a shift. Morning has a cross-offshore breeze, but the 6ft SW swell with a 16-second period is clean enough. The afternoon is where it’s at – 6ft SW, 16-second period, and a gentle offshore wind. That’s going to be clean and fun for experienced surfers, with moderate wave energy (1995).
Wednesday the 8th gets a bit tricky. The morning has a solid 10ft SW swell with a 17-second period, but the wind is cross-offshore, so it’ll be clean but a bit lumpy. The crowd factor is worth noting here – this spot can get busy, so expect company. The afternoon turns more to a cross-on, which messes with the shape a bit.
By Thursday the 9th, it’s backing off – 6ft in the morning with clean conditions, then dropping to 5ft in the afternoon but with a very long 18-second period. The cross-on breeze in the arvo will spoil it a little though.
Friday the 10th through Saturday the 11th is a write-off. Strong winds, cross-shore, and messy conditions. The swell is around, but it’s not worth paddling out in that. Take a couple of days off.
Sunday the 12th and Monday the 13th are dominated by strong onshore winds and big, ugly swell – 12ft to 13ft, but it’s blown out. This is more of a kite-surfing show than a paddle session.
Now, Tuesday the 14th is a real standout. Look at this: a 12ft SW swell with a 20-second period (10932 energy) in the morning, and a 10ft with a 19-second period in the afternoon. The wind is cross-shore from the south, so it’ll be lumpy, but the sheer power and size make it a very attractive option for advanced surfers. The energy is massive. This is the best session on offer for the second week, but it’s a long way out so treat it as promising rather than guaranteed.
The rest of the second week sees some size hanging around, but the wind isn’t always cooperating. Wednesday the 15th has 8ft to 10ft SW, but cross-shore winds. Thursday the 16th is similar but with more onshore influence. Friday the 17th is a mess.
However, keep an eye on Saturday the 18th and Sunday the 19th. Saturday morning has a 13ft WSW swell with a 16-second period, and a light breeze making it fairly clean. The energy is extreme (14053). This is a beast for experts. Sunday the 19th has a 12ft SW swell with a 15-second period in the morning and a light offshore from the NE – clean and powerful. The energy is strong (5453). Monday the 20th is similar, with a 12ft SSW swell, 17-second period, and a clean offshore. These days have the potential to be epic, but they’re a good 13-15 days out, so keep your fingers crossed for the forecasts to hold.
Overall, the first few days and the middle of the second week are your best bets. Don’t bother with the windy junk in between.
Rusty.

Information about the Flatrock Surf forecast
The above surf forecast table for Flatrock provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Flatrock can be found by selecting the local surf guide option on the grey menu. Our Flatrock 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 (Flatrock) 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 Flatrock 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.
