The Lowdown
Alright mates, let’s be real: Bay Street is a ghost town for waves right now. The first ten days or so are going to be a total washout for surf. You're looking at a big gap with barely a ripple out there, just tiny stuff under 2-2 feet that won't stand you up.
It’s a whole lot of nothing, with winds mostly onshore or cross-onshore. The one thing that's off the charts is the water temp—it's running about 6°F warmer than usual. It feels like a warm bath, but that's where the good news ends for a while.
We stay in the doldrums through the end of August. There are a couple of mornings around the 24th and 25th where the swell bumps to a foot and a half, but the energy is weak and the swell period is short, so it won’t have any shape.
Okay, now let's talk about the only real hope on the charts. As we get to the 29th of August, the swell finally wakes up. We're looking at waves pushing 3 feet from the SSW, with a solid 16-18 second period. The combined energy jumps to strong territory, hitting 511 to 619. That’s the real deal, but it’s still small enough for anyone. The winds are light, and while the mornings have that slight cross-onshore bump, it should clean up through the day. Saturday morning the 29th is your best bet—still not perfect, but it's the standout of the whole window.
The 30th and 31st keep similar size, around 3 feet, but the period shortens up, so it'll get a bit crumbly. Still, the afternoons with the lighter breeze are your best shot. After that, it’s back to dribble as we head into September. So keep your expectations low, but if you’re keen, that last weekend of the month is your only real shot.

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.
