The Lowdown
Alright, this is Rusty, and here’s the long-range picture for Kennack Sands.
To be straight with you, this is going to be a frustrating stretch. We’ve got a long, flat spell kicking us off. From this coming Sunday right through almost to the end of the second week, we’re staring at a whole lot of nothing. Days on end with barely a ripple, and what little shows up is too small or badly directed to bother with. You’re looking at a solid week-plus of no real surf on offer here.
Now, after that quiet spell, things do finally try to fire up around the middle of the second week. The standout, and really the only window worth circling, lands on Saturday the 15th and Sunday the 16th of August. It’s not groundbreaking, but it’s something. We see a pulse of easterly windswell push through, with wave heights building from around 6ft up to 8ft. The period is short, though, only 6 to 8 seconds – that’s local windswell, not a proper groundswell, so expect a bit of a bumpy, less organized wave. The combined energy jumps up, hitting moderate at first (225) and then strong by Sunday (541), so there’s power in the water, but it’s messy power.
Unfortunately, the wind is the real problem. For most of that spike, it’s cross or cross-off from the southwest, with speeds picking up to 19 mph on the Sunday. That will chop it up and make it tricky. The cleanest window looks to be Saturday afternoon, with a cross-off breeze, but even then, it’s only a “marginal” call. The best conditions actually fall on the Monday the 17th, when we get cleaner cross-off winds and a still-big 8ft swell, but the energy is maxing out (796), which puts this firmly in expert territory. For the average punter, that’s going to be a handful, and the short period will make it dumpy.
Overall, Kennack Sands is a beginner-friendly, sheltered spot that rarely sees big clean swell, and this forecast backs that up. This isn't a spot that handles a big, short-period easterly well. For the first week and a half, you’re better off finding something else to do. The last few days of the outlook offer some size, but the quality just isn’t there for a great paddle session. Keep an eye on it, but don’t hold your breath.
