The Lowdown

Alright, folks, Rusty here. Let’s be straight with you. The next couple of weeks are looking pretty average for Spanish Bay-South Moss. We’ve got a lot of small, mushy, onshore slop to wade through before anything with real grunt shows up. The water temp is sitting around 59.5°, which is pretty much normal for this time of year, so don’t stress about a freak cold snap.

The first few days are all about light cross-onshore breezes and wave heights hanging around the 4.5 to 5.5 feet mark. It’s not going to be a complete flat spell, but the energy is weak, with combined energy readings in the 500-670 range. That’s just not enough push to get the banks doing anything fun. The swell direction is mostly from the NW, which is not ideal for this spot. You’ll be fighting a bit of chop, especially in the afternoons when the breeze picks up slightly. Honestly, through the 9th to the 13th, it's a lot of paddling for not much payoff. There’s a slightly bigger pulse on the 10th, but the onshores will keep it messy.

Then, we hit a real lull from the 14th through the 19th. The swell drops right off, with wave heights barely getting over 3 feet, and the period is all over the shop. This is the lean part of the run. The combined energy here dips down to figures like 375-519, which is weak, weak, weak. It’s looking like a solid week of close-outs and groveling, if you can even call it that. The only thing that changes is the wind, but it doesn't matter much when there's nothing to work with.

Now, for a glimmer of hope. Into the back half of the window, around the 24th, there’s a late-breaking pulse. We start to see a more powerful, longer-period swell from the WNW pushing through with wave heights up to 7 feet and the combined energy jumping to 1067. That’s a significant bump from where we’ve been. It will be a different story out there, with a lot more push and size. The catch? The wind is still forecast to be cross-shore, but that might be a price worth paying. The quality isn't guaranteed, but this is the most interesting surf in the whole 16-day outlook. Keep an eye on that Monday, the 24th. It’s the one real standout on the horizon, but it’s still a week and a half away, so don’t book your day off just yet.

So, to sum it up: lots of small, clean-ish but weak surf for the first half, a proper flat lull in the middle, and then a late pulse of real size and energy to finish off the run. If you can be patient, the 24th is the day to circle on the calendar. Until then, keep the board waxed and the expectations low.
