The Lowdown
Alright, Rusty here, let's talk about what's coming for Rosie's Bay. Today is the 10th, so let's get into it.
Right off the bat, don't get too excited for today. There's a solid 6 ft swell on the way this morning from the WNW, but it's bumpy with a cross-onshore breeze. The energy is moderate (698), but it's just not clean. The afternoon gets worse; the swell jumps to 8 ft, which is too much for this break and the cross-shore wind chops it up. A write-off for a paddle.
Friday the 11th is where we get a real standout. The morning is glassy as it gets, and while the swell drops to 3 ft from the SW, it's a proper long-period groundswell at 17 seconds. That energy is still moderate (611), and with absolutely no wind, those waves will be clean and lined up. This is your session for the week. The water temp is around 59°, which is about normal for the time of year, so a spring suit is fine.
Later Friday and through the weekend, the swell stays small, around 3 ft to 3 ft, with that long-period SW swell hanging in there. Winds are light but variable, mostly cross or onshore, so it's marginal at best. Saturday morning might have a few with a light cross breeze, but nothing to get worked up about.
There's a long stretch of small, weak surf from Sunday the 14th right through to the end of the following week. Waves are mostly 2 ft to 3 ft, and while we get some glassy conditions on the 16th and 17th, the energy is low (below 300). The swell periods are still long, but there's just not enough size to get a proper ride.
Then, mark your calendar for Wednesday the 23rd of September. The morning looks excellent for experienced surfers. A 6 ft WNW swell is pumping in with moderate-to-strong energy (1050), and it's glassy. That's a powerful, clean wave for the crew who know what they're doing. It'll be too big for beginners, for sure.
Following that, Thursday the 24th morning holds a clean 5 ft W swell with glassy conditions, a nice follow-up session. And then the 25th is forecast for a big 10 ft WNW swell in the afternoon - that's expert territory only, and the winds won't be perfect. Still, keep an eye on that 23rd morning as the gem in the second week.
So overall, a bit of a flat spell in between, but Friday the 11th and Wednesday the 23rd are the ones to circle. Don't sleep on them.

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.
