Lyall Bay Surf Forecast and Surf Report

G'day, Rusty here, and I gotta be straight with you – this forecast for Lyall Bay is a tough one to call. We're looking at a 16-day window that's got a real mean streak, with a lot of wind and swell that's just not lining up. The first week is a write-off, honestly. We're talking about strong, howling winds from the NW and SSW, and the swell is either too small or blown to bits. The water's sitting at a touch warmer than normal for this time of year, but that's small comfort when you're getting sandblasted.

The first real glimmer of hope doesn't come until Monday the 14th of September. On that morning, the wind flips to a light offshore breeze from the north, and we've got a solid 6ft of S swell pushing in with a decent 11-second period. The combined energy of all swells is a solid moderate 922. This is the standout of the whole forecast. The waves will be clean, the wind will be light, and it's a genuine chance for a good session. The afternoon hangs in there too, with 5ft and a light northwesterly, still offering some clean lines.

But, and this is a big but, if that swell is too big for you, listen up. Earlier, on Sunday the 13th of September, we get a warning from the data. The morning sees a 12ft S swell with a 12-second period, but it's flagged as too big for this break. The afternoon is the same story with 10ft, but the wind turns offshore from the NNW. It's a powerful, clean, but huge swell. If you're an expert, that Sunday afternoon might be your window, but it's not for the faint-hearted.

Looking further out, the second week offers a couple of interesting possibilities. Thursday the 17th of September morning is a real tease. The wind goes glassy, dead calm from the east, and we've got a 8ft S swell with an 11-second period – that's a very good session on paper, with a combined energy of 1261. But it's a long-range call, so it's a promising but less certain one. The afternoon drops off a bit with a small cross-onshore wind creating some chop.

The bottom line? The first week is a total blowout. Monday the 14th of September is your best bet for a clean, fun, manageable surf. After that, keep an eye on the 17th for a potential glassy gem, but don't book your day off work just yet. For the rest of the time, the wind is just too strong or the swell is too big and messy. It's a waiting game.
