The Lowdown
G’day, it’s Rusty. Right, let’s have a look at the next couple of weeks at Rosie's Bay. It’s a bit of a slow burner, but there are a couple of windows where it could light up.
For the first few days, we’re looking at small, weak surf – nothing that’s going to get anyone too excited. The water temp is sitting around 60°, which is about normal for this time of year, so no surprises there. The swell energy is weak to moderate, with readings around 448 down to 204 units (moderate wave energy), but the waves are just too small and the winds are a bit messy. It's a case of waiting it out.
Thursday the 10th morning is the first real sign of life. The swell jumps to 7ft from the WNW with an 8-second period, and the energy is strong at 1222 units (strong to very strong wave energy). The wind is glassy, which would normally be a dream, but it’s flagged as too big for this break. That’s a lot of juice for a beach break, and it’s going to be a washing machine. Not one for the average punter. The afternoon drops to 5ft but the wind goes cross-shore, making it messy.
Friday the 11th afternoon is where we might get our first decent option. It’s 5ft from the W with a 9-second period and the energy is moderate at 664 units. The wind is glassy, and the notes say “expect very good surf conditions.” That’s the standout of the first week. It’s not huge, but it’ll be clean and fun.
After that, the surf backs right off again for several days. From the 12th through to the 18th, it’s mostly small, weak, and ordinary. We’re looking at a real gap here – nearly a week of hardly anything. There are a few glassy mornings, but with waves under 3ft, it’s just not worth paddling out for more than a splash about.
There’s a pulse on Saturday the 19th morning, but it’s another one that’s too big at 8ft from the WNW with an 8-second period. The energy is strong at 967 units, but with that short period and size, it’s going to be a close-out. The wind is cross-off, which is clean, but it’s not going to be a fun wave to ride. Might be more interesting for the kite crew than us paddle surfers.
The real golden window is Sunday the 20th morning. The swell is 6ft from the W with an 11-second period, and the energy is strong at 982 units (strong to very strong wave energy). The wind is glassy, and again the notes say “expect very good surf conditions.” This is the pick of the fortnight. That longer period means proper groundswell, and with offshores or glass, it should be lining up nicely.
There’s a final spike Tuesday the 22nd, but it’s another one for the experts only – 10ft from the W with a 12-second period and energy through the roof at 2751 units (strong to very strong wave energy). That’s big and powerful. Too big for most.
So, if you’re keen, keep Friday the 11th afternoon in the back of your mind, but the standout is Sunday the 20th morning. That’s the one to circle. It’s a bit further out, so we’ll have to see how it holds, but it’s looking promising. The rest is pretty much a waiting game.
Rusty.

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