The Lowdown
G’day, I’m Rusty. Let’s have a look at what’s on the cards for Rosie’s Bay over the next couple of weeks.
Right off the bat, we’ve got a bit of a flat start. The first proper surf recommendation doesn’t roll in until Tuesday, August 11th, and even then it’s pretty marginal. The swell is tiny at 2 ft from the SW, with a very long period of 15 seconds. That long period makes it a groundswell, which can be a bit tricky at a beach break – tends to jack up and close out. But with the wind light and offshore from the WSW, it’ll be glassy clean. The combined energy is weak (233). The water temperature is 60°F, which is pretty much spot on average for this time of year, so nothing unusual there. It’s a small one, but the clean conditions might tempt you.
We then go through a few days of cross-onshore winds and tiny swell, nothing really worth paddling out for. The energy stays low, and the conditions are poor. This stretch runs from Tuesday afternoon all the way through to Saturday morning, August 15th. It’s a long gap of nothing special.
Now, here’s where it gets interesting. Sunday morning, August 16th, we see a bit of a lift. The swell nudges up to 3 ft from the SSW, with a period of 16 seconds – still a groundswell, but the wind is glassy. That’s a major positive. The energy is moderate (440). It’s the first real standout, with clean, glassy conditions and a small but fun wave. It’s not big, but it’ll be smooth.
The best of the whole forecast, though, comes on Monday afternoon, August 17th, and Tuesday morning, August 18th. Monday afternoon has 3 ft from the SSW with a 15-second period, and glassy conditions – clean as a whistle. The energy is moderate (321). Tuesday morning is similar, with 3 ft from the SSW, 14-second period, and glassy winds again. The energy is a bit higher (420). These are the two standout sessions, no doubt. The waves will be small, clean, and well-shaped for an intermediate surfer. Crowds are possible at Rosie’s Bay, so get in early.
We also get a decent window on Wednesday morning, August 19th, with 3 ft from the W, a 12-second period, and glassy conditions. The energy is moderate (479). That’s another clean morning, but the afternoon gets blown out with a moderate cross-shore wind.
After that, the swell stays small, mostly cross-onshore, and the energy drops into the 200s again. From Thursday, August 20th, through to the end of the forecast on Wednesday, August 26th, it’s all marginal or poor conditions. The swell never really gets above 4 ft, and the winds are mostly cross-onshore or choppy. There’s one morning on Sunday, August 23rd, with a 3 ft swell from the WSW, but the period is short at 9 seconds, and the wind is cross-onshore, so it’s messy.
Overall, the best bet is Monday afternoon, August 17th, and Tuesday morning, August 18th, for clean, glassy, small waves. Everything else is a bit of a snooze. Keep an eye on the wind, and if it goes glassy, you might snag a fun one.
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.
