The Lowdown
Alright, grab your wettie, let’s talk surf.
Alright, listen up, it’s Rusty here. I’ve had a good look at the charts for The Breakwater-St Ives, and I’ve gotta be straight with you: we’re looking at a proper flat spell that stretches out for a while. There’s no surf worth talking about for well over a week. From now until the 23rd, it's just small, weak, and blown-out junk. You'd be better off tuning up your longboard or finding a rock pool to stare at. The water temp is sitting at about 65°, which is a touch warmer than normal for this time of year, so that's something, I guess. We're talking combined energies barely cracking three digits most days, with light onshores and cross-shore chop that'll just frustrate you.
Then, things finally start to change around Sunday the 23rd. Sunday morning looks like the one to circle on the calendar. This is the standout. We’ve got a solid 8ft groundswell rolling in from the west with a period of 8 seconds, but the important news is that a gentle southerly offshore wind kicks in, cleaning it right up. That’s a classic combo for The Breakwater. The combined energy is a meaty 787 (moderate wave energy), so there’s plenty of push. The water's still reasonably comfortable for an August dawny. Just keep in mind, when you get a 8ft west swell here, it’s gonna be a fair step up in size—definitely not one for the beginners. The Sunday afternoon session takes a hit though; the wind picks up to a fresh 19 mph from the south, making it a bit of a battle.
Monday the 24th still has some leftover energy with 4ft swell and clean conditions thanks to some light offshore cross-off winds, but it’s a smaller, weaker swell (around 233 combined energy) and the direction swings north, which isn’t the optimum west-northwest this break likes. It’s surfable, but nothing to write home about.
So, in short: be patient. The first ten or eleven days are a write-off. The only true standout window is the morning of Sunday the 23rd of August. If you’ve got a big-wave board and you don’t mind a bit of a paddle, that’s your shot. Otherwise, wait and see if the later forecasts improve.
Rusty.
