Table - best surf conditions forecast for Bay Street over the next 16 days.
The Lowdown
Alright folks, Rusty here. Let’s get into it for this spot. The window’s looking pretty quiet overall, so we’re gonna have to be patient and pick the right moments.
We’ve got a long stretch of nothing much to start. The first few days are mostly a write-off, with tiny swell and poor conditions. The few sessions that pop up are just marginal, not really worth paddling out for. There’s a real gap of unremarkable surf until the following week.
The best chance we get is on the morning of Monday, September 21st. Bay Street is seeing a 3ft swell from the SW, with a 17-second period. That’s a long period groundswell, which will bring some real shape and energy. The combined energy is moderate at 384. The wind is light and cross-shore from the SSE, which will keep the surface clean. It’s a fairly consistent break, so it should be breaking. The water temp is about average for this time of year, nothing weird going on. This is the standout of the whole forecast – a proper little window where the conditions align.
A couple of other mornings are worth a look if you’re desperate. The morning of Wednesday, September 23rd has a 2ft SW swell (15s period) with light offshore wind, which is a major positive for clean faces. The combined energy is moderate at 225. It’s going to be glassy, but it’s still a small wave. The afternoon of the same day has a clean cross-offshore wind from the SE, but it’s a bit stronger and the wave height is similar.
Overall, it’s a pretty flat run. The Monday morning is the only true standout. Don’t get your hopes up for the rest of it.
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.
