The Lowdown
Alright folks, Rusty here. Let's take a look at this stretch of coast.
First thing, the water temp at Bay Street is a balmy 73°, which is a solid 7° warmer than normal for this time of year. That's a real bonus.
The honest truth is, the surf is looking pretty quiet for a while. The first real window of opportunity doesn't open up until Sunday morning, September 6th. Before that, it's all onshore slop and tiny waves.
The standout period is Sunday, September 6th. The morning is looking clean with a light cross-offshore breeze from the ESE at 9 mph, pushing a 3ft SSW groundswell with a 15-second period. That long period means good shape and energy, with a combined swell energy reading of 493 (moderate). But the absolute best is Sunday afternoon. The wind goes completely glassy, dead calm, and the swell ticks up a hair to 4ft from the S, with a 14-second period. The energy is 537 (moderate). This is the pick of the forecast – glassy, clean faces, and just enough push for a fun session. This spot breaks fairly consistently, so you'll get waves. It can get a bit crowded sometimes, so expect to share.
Monday, September 7th, the swell builds to 4ft (S, 13 seconds, energy 678 – moderate), but the wind swings onshore from the SSW at 6 mph, messing up the surface. Tuesday sees similar swell size but the onshore wind stays, and quality nosedives.
From there, it's a long, slow fade. From Wednesday, September 9th, all the way through the end of the forecast on September 19th, the surf is small and mostly blown out. There are a few mornings with a light cross-off or cross-shore breeze, like Saturday the 19th, but the swell is down to 2ft with a long 19-second period – not enough grunt to work with, and the energy is weak (356). On September 14th, there's a brief blip of 3ft swell but with a terrible 6-second period and a cross-onshore wind. That's just a choppy mess.
So, the bottom line: Sunday afternoon, September 6th, is your day. Make the most of it, because after that, it's a long dry spell of nearly two weeks.
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.
