The Lowdown
Alright, folks, Rusty here. Let’s talk about what’s happening at Rosie’s Bay for the next couple of weeks.
To be honest, the first ten days are a real drag. From Saturday the 8th all the way through Monday the 17th, it’s pretty much flat. The swell is tiny, mostly 1ft to 2ft, with a 15 to 18-second period, which is a long-range groundswell, but there’s no size to it. The wind is constantly cross-onshore, and the water temp is about average for this time of year. The combined wave energy is weak, running between 147 and 561, so it’s just choppy and weak. For a spot that’s very consistent, this is a tough stretch.
Now, the good news. Tuesday the 18th is where it turns on. Tuesday afternoon is the real standout. We’ve got a solid 7ft swell from the west, with a 12-second period, and the combined energy jumps to a big 1360. The wind goes glassy, which is about as clean as it gets. That’s a day for experienced surfers, as 7ft is getting into the expert range. The west swell direction is a good match for the bay. Crowds are sometimes a factor, so don’t expect to have it to yourself.
Wednesday the 19th is also worth getting out for. Wednesday afternoon is glassy again, with a 4ft west swell at 9 seconds. That’s a bit shorter period, but the energy is still moderate at 515, and the clean conditions will make it fun for intermediates. The morning of the 19th is a touch smaller with a cross-shore wind, but still surfable.
After that, from Thursday the 20th onward, the swell drops back below 3ft, and the wind gets messy again, so it’s back to marginal stuff. The run from the 8th to the 17th is a near ten-day gap with no real surf, so you’ll be waiting until the 18th for the good stuff.
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.
