The Lowdown
Alright folks, Rusty here with the long-range look at what's coming our way for Rosie's Bay.
Overall, this is a strange one. We've got a bit of a flat start before a run of smaller, clean waves, but the real energy is all stacked at the very end of the 16-day window. It's a slow burn, but there are a couple of sessions that are worth circling on the calendar.
### The Outlook
Right now, nothing is happening. The first few days are a write-off with marginal conditions and poor quality, so we're just sitting and waiting. The first real glimmer is on Thursday the 3rd. It's not big, with a 5ft swell from the W, but the wind is glassy. That’s a huge positive. Expect clean, fun little waves that are easy to handle. The combined energy is moderate (587), so there’s enough push for a longboard or a fish.
That glassy spell hangs around for a few days. Friday the 4th and Saturday the 5th both have clean mornings with glassy conditions. Swell drops a bit to 2ft from the SSW, but the period is very long (18-19 seconds). That means longer lulls between sets, making it easy to paddle out, but the waves could be a little tricky as that long-period groundswell tends to stand up and go straight at a beach break. Still, with glassy conditions and crowds only *sometimes* a problem, these are great mornings for a quiet paddle.
Then we hit a long, dry patch. From Sunday the 6th right through to the 13th, it's mostly cross-onshore winds and marginal conditions. The swell is small, the wind direction is messy, and it’s just not worth paddling out for. The one exception is a cracker of a morning on Thursday the 10th. Glassy conditions again, with a clean 3ft W swell and a decent 11-second period. The combined energy is strong (550), promising plenty of push. That’s the best call in this whole quiet stretch.
Now, the standout. Forget the small stuff. The real event is locked in for Wednesday the 16th of September. The morning brings a solid 6ft swell from the WSW with a 10-second period. The wind is glassy, the skies are clear, and the combined wave energy is a powerful 883. This is the heavy-hitter of the outlook. For an intermediate break, 6ft is on the upper edge of comfort, but the clean, glassy conditions and that solid W/NW groundswell will groom it into proper waves. The only caveat is the shortish period means the sets will be more frequent and a bit more challenging. This is the day to be in the water.
So, for the best on offer: the Saturday the 5th of September morning for small, glassy, mellow waves, and the Wednesday the 16th of September morning for the main event – bigger, cleaner, and full of energy.
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.
