The Lowdown
G'day, Rusty here. Looks like Rosie's Bay is the only spot on the radar, and it's a bit of a mixed bag for the next couple of weeks. We've got a run of slow, small days to kick things off, but there's some real promise further down the track if you're patient.
First up, the water temp is sitting about average for this time of year, so nothing too wild there. The swell energy is weak for the first few days, hovering around 213 to 286 (moderate energy). Thursday afternoon the 27th of August is the first sign of life, with a clean 2ft SW swell and a light cross-off breeze. It's small, but it's rideable.
Friday morning the 28th of August is a standout for a micro session – glassy conditions with a 1ft SSW swell and a long period of 19 seconds. That's a proper groundswell for the size, so it'll have some push, but it's really only for the longboard or a foamie. The energy is moderate at 258.
We hit a bit of a lull from Saturday the 29th through to Monday the 31st of August, with marginal to poor conditions and light cross-shore winds. The swell stays small, around 2ft to 3ft, and the energy builds to moderate levels (around 391 to 576) but the quality isn't there.
Now, the first week of September brings a change. On Tuesday the 1st of September, we see a 5ft W swell coming in with a short 9-second period, and the energy is moderate at 508. The wind is cross-shore, so it's a bit bumpy. Wednesday the 2nd of September is a big one – the swell jumps to 7ft from the West with that same short period, and the energy is strong at 984. The wind is light and cross-shore, but at this size, Rosie's Bay is going to be a handful. The forecast says it might be too big for this break, and I'd say that's spot on – this is strictly for experienced crew only, and even then, it'll be a challenge.
The best of the entire run, and the one to circle on your calendar, is Sunday the 6th of September. Afternoon sees a 5ft WNW swell, a period of 11 seconds, and a clean cross-off breeze. The energy is strong at 666, and the conditions are expected to be very good. That's your session right there – solid size, clean lines, and a decent period. A close second is Wednesday the 9th of September afternoon, with a glassy 2ft SW swell and a long 18-second period, giving you that clean, long-period groundswell feel. Energy is moderate at 593.
The final standout is Thursday the 10th of September morning – glassy again with a 3ft SW swell and a 17-second period. Energy is moderate at 558. It's a lovely way to wrap up the outlook.
Overall, don't expect much until the end of the first week of September. The big winner is Sunday the 6th, with Wednesday the 9th and Thursday the 10th as solid backup options. Keep an eye on the forecast for that 7ft day on the 2nd if you're a charger.
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.
