Rosie's Bay Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s take a long look at what’s cookin’ at Rosie’s Bay. It’s a bit of a mixed bag for the next couple of weeks, but we’ve got a few windows of glory to keep an eye on.

We start off from Saturday, August 29, with a clean but tiny swell. Morning sees a 2ft SSW groundswell at a very long 17 seconds with a light SW breeze – glassy as can be. The combined energy is weak (474), so the surf is small. The water temp is about average for the time of year. This pattern of small, clean, long-period swell carries through the weekend, but the wave heights are only in the 2ft to 3ft range. It’s marginal, but the glassy conditions on Monday afternoon (August 31) with a 3ft SSW swell and 15-second period (491 combined energy) will be a nice session for a log or a mid-length if you’re patient.

Tuesday, September 1, is a write-off with moderate to fresh breezes and rain, so give it a rest.

Here’s the big one to circle on your calendar: Wednesday, September 2. The morning brings a 7ft S swell, but here’s the catch – it’s short period at 8 seconds, and the combined energy is strong (1161). The cross-shore wind is moderate, and the wave comment says it’s predicted to be too big for this break. This is expert territory only, and the short period means it’s not going to be the cleanest. For a safer bet, the afternoon drops to 6ft from the W at 11 seconds, but with a fresh cross-shore and cross-chop, it’s still a messy, powerful zone. This setup is honestly looking more interesting for kite surfing than a paddle session.

We get a nice reprieve from Thursday, September 3, through Friday, September 4. The mornings are pure glass. Thursday morning has a 4ft S swell at 8 seconds (310 combined energy) and Friday morning a 4ft S swell at 8 seconds (324 combined energy). Both are glassy with a slight air. This is clean, fun-sized surf for the intermediate surfer. The short period means you’ll get a bit more punch but shorter rides, so it’s a beach-break grovel.

After Friday, the swell drops back to the 2ft to 3ft range for the next week, with mostly cross-on winds. The standouts here are Monday, September 7, morning, and Tuesday, September 8, morning. Tuesday morning (September 8) is a total glass-off with 2ft SSW swell at 14 seconds (297 combined energy). It’s small, but it’s perfect. The long period will make it a bit walled up at a beach break, but on a sandbar it’ll be fun.

The best, most consistent push of the run comes around the 2nd week. Friday, September 11, has a 3ft SW swell at 17 seconds (446 combined energy), but the wind is cross-shore from the SE, making it marginal. The true standout is Sunday, September 13, morning. A 2ft swell from the W at a very long 19 seconds (617 combined energy) with a light cross-shore breeze. That’s a long, clean roller for a point or river mouth if you can find one. But it’s inconsistent, so you’ll be waiting for sets.

Best on offer: The glassy mornings of Thursday, September 3, and Friday, September 4, offer the best combination of clean conditions and rideable swell (4ft). For a longer-term, patient bet, the glass-off on Tuesday, September 8, morning is a true gem for a small-wave board. The big swell on September 2 is for experts only.

Rusty.
