The Lowdown
Alright folks, Rusty here. Let's have a look at what Rosie's Bay has on offer for the next couple of weeks.
We're looking at a bit of a mixed bag, but there's some real gold hidden in there if you're patient. The longer-period swells are the ones to watch, especially when they line up with some clean wind.
Things kick off this Thursday, July 30th, with a solid 3ft swell from the SSW, but it's a bit short on quality with a cross breeze. The morning's a write-off. Friday afternoon, July 31st, is where it starts to get interesting. The wind goes glassy, and we get a 3ft, 15-second period SSW swell. The energy is moderate (708), and it'll be clean. Not a huge wave, but a real fun one for an intermediate.
Saturday and Sunday look pretty grim with rain showers and onshore winds, so give those a miss. The first real standout comes on Wednesday, August 5th. The morning is glassy with a 6ft, 9-second WNW swell, and the combined energy is moderate (546). That's a classic early session. But the real headline is the afternoon. The swell bumps up to 7ft from the WNW, still with a 9-second period. The energy jumps to a strong 1157, and the comments say it's too big for the break. For those of you who are expert-level, this is going to be a beast. The wind is a light cross-shore, so it'll be a bit lumpy, but the power is undeniable. The following morning, Thursday, August 6th, is also glassy with a 5ft swell, a great follow-up session.
Things get a bit messy after that, with a lot of onshore and cross-onshore winds through the next week. The swell stays moderate, but the quality drops. Then, another treat. On Wednesday, August 12th, the afternoon goes glassy again. The swell is a tiny 2ft, but it's a very long-period groundswell from the SW with an 18-second period. The combined energy is moderate (537). At a beach break, a period that long can make the waves a bit too straight, but for a clean, glassy, long-period wave, it's a beautiful thing for a longboard or a fish. It's a great, quiet session to round out the outlook.
Best on offer: The standout is definitely the afternoon of Wednesday, August 5th for the experts who can handle the size, with the glassy morning of Thursday, August 6th as a close, more manageable second.
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.
