The Lowdown
Alright, crew, Rusty here with the long-range look. For Spanish Bay-South Moss, the next 16 days start off pretty grim, but there's a little light at the end of the tunnel if you're patient.
Right now, the water's at 59°, which is pretty normal for this time of year.
The first few days are a total loss. Friday and Saturday are flat and junk, with tiny 1ft to 2ft waves and a weak, long-period swell. The energy is weak (273 to 343). Just leave the board in the car.
We get a bit of a bump on Sunday the 9th, with a 6ft NW windswell, but the period is a short 10 seconds and it's cross-onshore. It’s going to be messy, with moderate energy (756). It's a "maybe" day, not a "go" day.
From Monday the 10th through Thursday the 13th, we've got waist to chest-high surf with short, crumbly periods. The wind is light, but onshore, keeping the surface bumpy. It's all pretty mediocre, with the energy in that moderate range (424 to 767).
But, the real standout is Thursday afternoon the 13th. The swell drops to about 4ft, but the period jumps to a very long 12 seconds. This is proper groundswell. The wind, a cross-shore 12 mph, isn’t ideal, but the wave shape will be way better. The energy is moderate (547). This is your best chance for a clean, lined-up wave.
After that, it fades back out on Friday, and the weekend brings a very minor and inconsistent SSW swell that doesn't really do much.
All in all, we’re looking at a lot of blown-out, short-period junk. The one window to zero in on is Thursday afternoon. Don’t get too hyped for anything else.
For the beginners out there, any day over 5ft might be a handful. For the rest of us, it's a lot of paddling. And with the bigger, windier NW swells, this exposed spot might be better suited for a kite than a surfboard.
So, mark your calendars for Thursday the 13th. Otherwise, keep your expectations low. Forecasts this far out can shift, but right now, that's your shot.
Rusty, signing off.
