The Lowdown
Alright, Rusty here. Let’s have a look at what’s on offer for the next couple of weeks.
First off, I gotta be straight with you – it’s a lean run. The whole 16-day window is basically a flat spell with only a whisper of swell, and the winds are mostly onshore or cross-onshore, which is not what we want. You’ll be waiting a long stretch of days before anything even looks close to rideable. The only break available is Bay Street, a beginner-friendly spot that’s fairly consistent, exposed to a WSW swell direction. The water temp is about average for this time of year.
Right now, through the 16th and for the next week or more, it’s just not happening. The swell is tiny – 1 ft to 2 ft – and the wind is onshore from the SSE or SW most of the time, making for choppy, poor conditions. There are a few mornings with a light cross-onshore breeze, but the energy is weak, with combined swell energy readings in the low to mid hundreds (119–339), and the wave comments are all poor or marginal. It’s a long, quiet stretch.
The only time that even raises an eyebrow is right at the very end. On Thursday morning, the 1st of October, we finally get a glimpse of something. Bay Street shows 1 ft of swell from the SW, with a generous 18-second period – that’s a long-period groundswell, which usually brings better shaped waves and longer gaps between sets. The best part? The wind goes glassy, dead calm, with a slight air. That’s a rare treat and will make for clean, glassy conditions. The combined swell energy is only 142 (weak), so it’s not a big day, but for a spot that’s been flat, this is the one. Keep an eye on that morning; it’s the only chance for a clean little session. The break is Bay Street, and it’s exposed to a SW swell, so you’ll want that direction.
The rest of the period? Honestly, it looks more interesting for a kite surfer than a paddle surfer, with the onshore wind and small, bumpy waves. But for a wave count? Nope. The standout is that Thursday the 1st of October morning – it’s the only show in town, and with glassy conditions, it could be a real treat for the beginners and longboarders.
Stay hopeful, though – it won’t stay this flat forever.
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.
