Rosie's Bay Surf Forecast and Surf Report

G’day folks, Rusty here. We’ve got a solid run of clean, small to medium swell on the cards for Rosie’s Bay, but you’ll need to pick your moments. The standout session is the Thursday 10th September morning with long-period groundswell from the SW, clean and glassy conditions, and moderate wave energy (706). The Friday 11th September afternoon is also a ripper – glassy, clean, and building to 3 ft of SW swell with strong energy (701). On the other hand, Sunday 13th September morning sees a big pulse of 6 ft WNW swell with offshore wind and a short period of 8 seconds – it’s clean and powerful, but that afternoon the swell jumps to 10 ft and the break can’t handle it, so for experts only the morning there. Water temperature is sitting at 59°, which is about average for this time of year.

For the first few days: Friday 4th September morning is small but glassy – 2 ft SSW swell with a very long period of 19 seconds (447 energy). It’s clean and surfable, not big but fun. The afternoon stays glassy with 2 ft SW (526). Saturday 5th September morning is another beauty – 3 ft SSW and glassy (525). Saturday afternoon the wind swings cross-on and it gets chopped up – give it a miss. Sunday 6th and Monday 7th are marginal with cross-on or onshore winds, the swell stays 3 ft but the quality drops off. Tuesday 8th morning returns to glass with 2 ft SSW (263). Wednesday 9th morning is glassy again with 2 ft SSW (378).

Then we hit the highlights: Thursday 10th morning is the real gem – glassy, 2 ft SW with a long period of 17 seconds and energy at 706. Friday 11th morning is a bit bigger at 3 ft SW with onshore wind, but the afternoon cleans right up – glassy, 3 ft SW (701), and really good.

Saturday 12th is a mixed bag: morning is cross-shore breeze with 3 ft SW (619), afternoon gets a new 5 ft WNW swell at short period (10s) but it’s cross-shore and messy. Sunday 13th is a big day – morning has 6 ft WNW with offshore wind and short period of 8 seconds, clean but powerful (817). That afternoon the swell pumps up to 10 ft WNW – way too big for this spot. Monday 14th has 8 ft WNW in the morning, also too big, and then a strong cross-on breeze with 7 ft waves in the afternoon – that’s more for kite surfers than us.

The second week tails off: Tuesday 15th morning is glassy 3 ft W (368), decent. Wednesday 16th morning is glassy 5 ft W (436) – solid. Thursday 17th morning glassy 3 ft W (305). Friday 18th onward the wind picks up strong from the WNW, and the swell drops to under 3 ft with a very long period but choppy conditions – not worth it. Saturday 19th is similar, messy and small.

Overall, the best bet for clean, long-wave, shoulder-high fun is Thursday 10th morning, with Friday 11th afternoon as a close second. The Sunday 13th morning session is for experts only with that punchy 6 ft swell. Longer term, keep an eye on Tuesday 15th and Wednesday 16th mornings for glassy windows.

Rusty.
