The Lowdown
Alright, Rusty here. Let’s have a look at what Rosie’s Bay has in store for us over the next couple of weeks.
We’re looking at a pretty quiet run for a while. The first real suggestion of anything worthwhile doesn’t show up until the middle of the month, and even then it’s marginal. The water temp is sitting around 58°, which is pretty much what you’d expect for this time of year, nothing unusual there.
The first chance for a surf comes Monday morning, September 14th. We’ve got a small 2ft SSW swell, period around 13 seconds, and a light cross-off breeze from the ESE. The energy is moderate (269), and it should be clean. It’s not big, but it’s a start.
Tuesday morning the 15th looks glassy with a tiny 1ft SW swell, but the period is a very long 17 seconds. That’s a groundswell, and while it means clean conditions, that long period can make a beach break like this a bit straight and tricky. Energy is moderate (259). It’s a session for the log, not for charging.
Saturday the 19th is another glassy morning. A 2ft SW swell, 19-second period again – very long period, so the same caveat applies. The energy is moderate (368). It’s going to be clean but small.
Now, there’s a shift around the 22nd of September. Tuesday the 22nd afternoon is where it starts to get interesting. We see a jump in swell to 6ft from the W, period 13 seconds, with glassy conditions. The energy kicks up to strong (1468). That’s a proper swell for an intermediate surfer. For the more experienced crew, this is the standout of the run.
Wednesday the 23rd afternoon also looks good. A 5ft W swell, period 12 seconds, with a light cross-off breeze from the NNE keeping it clean. Energy is strong (893). That’s another solid option.
Thursday the 24th morning is a no-go. The swell is predicted to hit 8ft from the WNW, which is too big for this break, especially with the period at 11 seconds. That’s expert territory and a fair step up.
Friday the 25th morning is back to more manageable conditions: glassy, with a 4ft W swell, 10-second period, and moderate energy (470).
The following week gets a bit wild. Sunday the 28th morning is too big again, with a 7ft WSW swell and glassy conditions – that one’s for experts only, if anyone’s brave enough.
So, the standout here is the afternoon of September 22nd: 6ft W swell, glassy, strong energy. That’s the one to circle on the calendar. The 23rd afternoon is a close second. The rest of the time, it’s small and clean, but nothing to get too excited about until that mid-week pulse.
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.
