The Lowdown
Right off the bat, it’s looking pretty bleak for Spanish Bay-South Moss. The next week is a write-off for any decent waves. We’ve got a gap of about six days with nothing but tiny, weak surf and crummy cross-onshore winds. You’d be paddling around for nothing.
The first real glimmer shows up on Sunday the 9th. The swell bumps up to 5ft, but it’s coming from the NW with a short, jumbly 9-10 second period. The energy is moderate (707). It’s messy, and the wind is still on it, so it’s not going to be pretty. This is really just a sign that things are starting to move.
The whole stretch from the 9th through the 14th is a frustrating tease. We’ve got 5ft of swell, but the period stays short, and the wind keeps messing with it. It’s always cross-on or cross-shore, never clean. The energy is moderate, but it’s wasted. This isn’t the kind of surf you’d get excited about unless you’re desperate for a wave.
Finally, on the 15th and 16th, the swell drops to 3ft, but the period stretches out to 16 seconds. That’s proper groundswell. The energy is still moderate (635). The wind is still cross-on, but it’s lighter. The morning of the 15th looks the best of the run, but it’s still marginal. You’d get some clean-ish lines, but it’s not going to be a classic.
The one standout, and I mean the only one worth circling on the calendar, is the morning of Tuesday the 18th. The swell is only 3ft, but the period is a clean 14 seconds from the SSW. The wind finally turns cross-offshore, and the report says it’s clean. The energy is moderate (259). This is your window. It’s not big, but it’ll be glassy and lined up. For this spot, that’s the best you’re going to get. The afternoon, though, is blown out by a 40 km/h cross-off, and the next day the wind swings onshore. So it’s a one-morning window.
After that, it’s back to tiny, poor surf and onshore winds. The 19th and 20th are just a letdown.
So, in short: don’t hold your breath for the next week and a half. If you’re keen, the morning of the 18th is the only real surf. Everything else is a gamble. The water temp is about average for the time of year, so at least you won’t be freezing while you’re waiting.
This is a stretch where you earn your keep, mate.
