The Lowdown
G’day, Rusty here, lookin’ at the next couple of weeks at Rosie’s Bay. It’s a bit of a mixed bag, but there’s a couple of windows that’ll get your heart pumpin’. First thing Friday morning, the water’s sittin’ at 58°, which is pretty much spot on for this time of year – no weirdness there.
Right off the bat, Friday morning, the 17th of July, we’ve got a clean-looking 3ft swell rollin’ in from the west, with a solid 11-second period. The wind’s barely a whisper from the southeast at 6 mph, keepin’ it cross-shore. The wave energy’s moderate at 508. It’s not epic, but it’s a solid start. Then Friday afternoon, the wind drops to glassy – 3 mph from the east-southeast – and the swell’s still hanging around 3ft, though it’s shifted a touch to the west-northwest. That’s a nice little session if you can sneak out.
Saturday the 18th is a write-off, though. The wind’s cross-on, and the swell’s all over the place. Sunday and Monday aren’t much better—cross-on winds and messy little waves. You’ll be fightin’ chop.
Now, Tuesday morning the 21st is a gem. The wind goes glassy out of the south-southwest at 3 mph, and we’ve got a tiny but clean 2ft groundswell from the southwest with a very long 16-second period. Wave energy’s weak at 334, but for a small-wave board or a longboard, that’ll be buttery smooth. Wednesday morning the 22nd is another one to circle – glassy again, 5ft from the west-northwest at 8 seconds. It’s a bit short-period, but clean faces are on offer.
The real standout, though, is Sunday the 26th of July. Sunday morning, the wind’s glassy from the southwest at 3 mph, and we’ve got a 3ft groundswell from the southwest with a very long 21-second period. The wave energy is strong at 628. That’s a proper, long-period groundswell – it’ll stack up nice and smooth at a place like Rosie’s Bay. It’s small, but the quality will be there for a patient surfer. The afternoon gets a bit sloppy with cross-on wind, so get out early.
The second week is a bit of a tease. Monday the 27th and Tuesday the 28th have some solid energy—over 1000 in the combined swell—but the wind’s cross-on and choppy, especially in the afternoons. Wednesday the 29th and Thursday the 30th of July hold the most promise for the back half. Thursday morning has a 4ft swell from the south-southwest, 16-second period, and the wave energy is very strong at 1203. The wind is light cross-on from the south-southwest at 6 mph, so it’ll be a bit bumpy, but that’s a lot of juice. It’s more of a long-range ‘maybe’—keep an eye on it, but don’t book the week off.
After that, it fades out. Friday the 31st and into the 1st of August, the swell drops and the wind gets messy. All in all, the best call is Sunday morning the 26th of July—glassed-off, long-period groundswell, and no crowds to speak of. The Tuesday the 21st is a close second for a clean, tiny-wave session. The rest of the time, you’re either fighting the wind or waiting for the next pulse.
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.
