The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the table for our stretch of the lake.
Straight up, I gotta be honest with you: this is a tough one. We're looking at a solid 16-day window, and for the first week, there's pretty much nothing doing. The forecast is showing a big, long gap of flat, poor surf conditions from now right through to Saturday the 15th of August. We've got glassy mornings and clean afternoons, but with zero swell energy, it's just a paddling pool out there.
The first real whisper of a wave shows up on Sunday, the 16th of August, but it's a sad little thing. We're talking about south-west swell pushing in at a tiny 1ft with a period of just 3 to 4 seconds. That's windswell, and it's weak. The combined energy is a measly 3 to 7 (weak energy). With a moderate cross-onshore breeze, it's going to be choppy and messy. Not one for a paddle out unless you're desperate to wet the board.
After Sunday, it’s back to nothing. The lake goes flat again. We get some nice offshore and glassy conditions on Monday the 17th and again on the 23rd, but there's simply no swell to go with it. There's no wave energy to speak of. It's a long, flat run, and this is one of those times where the lake just shuts down. This sort of blank run is pretty normal for the area when the wind and swell don't line up. Forecasts can always change, but for now, all we can do is wait.
Alright, I’m going to be straight with you: there isn't a single standout in this 16-day stretch. The only break we're looking at is Port Colborne. It's exposed to a south-southeast swell, which is the right direction, but the swell just never shows up with any meaningful size or period. The crowd factor here is listed as "sometimes," but with no waves, the crowds won't be an issue anyway. It's a massive bust.
If you really need to get in the water, wait for one of those clean, glassy mornings later in the period, like Sunday the 23rd of August. The water temperature is about average for the time of year, but without any swell, it's a swim, not a surf.
So, that's the grim picture. No waves on the horizon for a while. Keep your board in the car just in case, but don't hold your breath.
Rusty.
