The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ for Whitsand Bay and Tregantle over the next couple of weeks.
First off, I gotta be straight with you—this is a grim run. There’s a solid 11-day stretch of flat to tiny, onshore junk ahead. The water is a weird 67° right now, which is *much warmer than normal* for this time of year, so at least you won’t freeze while you’re starin’ at a lake. From Monday the 20th right through to Thursday the 30th, we’re looking at waves barely a whisper—0.3 ft to 2 ft—with short, weak periods and a combined energy that barely cracks double digits (5 to 40). Most of the time the wind is cross or onshore, making it choppy and messy. The one bright spot is a few glassy mornings—like Friday the 24th morning and Wednesday the 29th morning—but with nothing to ride, it’s just a pretty pond.
The drought finally breaks on Friday the 31st of July. That morning, an ENE wind of 22 mph is blowin’ clean cross-offshore, and we get a sudden spike in swell: 6 ft from the WSW at a 7-second period. The combined energy jumps to 311—that’s moderate power, but it’s a short-period wind swell, so it’ll be a bit lumpy and walled up. By Friday afternoon, it pushes to 7 ft from the WSW with an 8-second period, and the energy rockets to 846. That’s the biggest swell of the whole outlook, and with clean cross-off winds, it’s the standout. But listen—that 7 ft is expert territory, and with only a short period, it’ll be a bumpy, powerful closeout at a beach break. This one is for the experienced crew only.
After that, it drops off quick. Saturday the 1st of August sees 3 ft leftover from the SSW, but by then the wind is swinging onshore, and the energy is back down to 80. By Sunday the 2nd, we’re back to weak, onshore slop, and it stays that way through the 4th of August, with a 6 ft onshore mess on Tuesday the 4th that’s more of a kite-surfing scene than a paddle session.
So here’s the deal: the only real chance to get wet is Friday the 31st of July, and that’s a big, powerful, short-period swell for experts only. Everyone else, you’re lookin’ at a long dry spell. Forecasts can change, but right now, this stretch is a tough one.
Rusty.
