The Lowdown
Alright folks, Rusty here. Let’s talk about what’s coming up at Bay Street over the next couple of weeks.
Honestly, it’s a tough stretch. The forecast is lean, and there’s a lot of onshore wind messing things up. The water is sitting at a balmy 74°, which is a wild 8° warmer than usual for this time of year – that’s seriously unusual.
We start off pretty flat on Thursday, September 3rd, with a tiny 1ft SW swell and a light cross-on breeze. That’s a no-go. The energy is weak, with a reading of just 187. Friday and Saturday see a bit of size creep up, with the swell hitting 3ft to 3ft from the SSW, but the wind is either on or cross-on, keeping things messy. The energy is building into the moderate range (566 by Saturday morning), but the quality isn't there.
The one real glimmer of hope comes on Sunday, September 6th. Morning glass-off conditions with a 3ft S swell, period of 14 seconds – that’s a proper groundswell. The energy is solid at 476. For a couple of hours, it’ll be clean and lined up. That’s the best we’ve got. The afternoon gets spoiled by onshore wind again.
Monday the 7th and Tuesday the 8th are frustrating. The swell holds around 3ft to 4ft, and the energy is pumping (over 500), but the wind is onshore from the SW all day. It’s going to be bumpy and blown out. Not worth the paddle.
We drop off again mid-week, with the 9th and 10th seeing the swell back down to 2ft to 3ft, and the wind refusing to play nice. The long period (17 seconds) on the 10th would be great for a point break, but at a beach setup like this, it’ll probably just break too straight.
The second week is flat and forgettable. From the 12th onwards, we’re looking at tiny waves – 1.0ft to 2ft – with near-constant onshore wind. The energy drops off a cliff (down to 134 on the 13th). There’s a very long period swell (22 seconds) on the 17th of September, but at 1ft, it’s just a bump on the water. No good.
So, to sum it up: Sunday morning, September 6th, is your only real window. Get in early for clean 3ft SSW groundswell before the wind wrecks it. Everything else is a write-off. There’s a long stretch of nothing from the 10th through the 18th, so don’t hold your breath.
Rusty.

Information about the Bay Street Surf forecast
The above surf forecast table for Bay Street provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Bay Street can be found by selecting the local surf guide option on the grey menu. Our Bay Street 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 (Bay Street) 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 Bay Street 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.
