The Lowdown
Alright, mate, Rusty here. Let’s be straight with you. Looking at the next couple of weeks, it’s a bit of a grim picture for the surf out at Whitesand Bay. We’ve got a long stretch of small, weak, and messy waves, and honestly, there’s nothing here that’s going to get the heart racing. The good news is, near the very end of the window, there’s a glimmer of something that might just be worth a paddle, but we’ve got a lot of flat, blown-out days to get through first.
Right now, and for the first week, it’s really not looking good. We kick off with tiny, poor surf. The energy is weak, with combined readings mostly under 100 (48, 13, 9), and the wind is all over the place, adding a cross-chop to the already small swell. Saturday the 15th is a write-off. Sunday the 16th is even smaller. The beginning of the next week sees a slight bump on the 18th, with a combined energy of 123, but it’s still just a messy 3.9ft of cross-onshore slop, and the period is a weak 6 seconds. It’s not surf, it’s just whitewater.
The pattern continues through the 19th and 20th – more of the same. There’s a bit of a shift on the morning of the 21st with a clean cross-offshore wind, but the swell is still tiny and weak. The energy is only 99, and it’s not enough to push over the sandbar properly. This is a stretch where you’d be better off finding something else to do. It’s a long, blank run.
Then, we finally get a sign of life. Saturday the 22nd, early, the wind swings offshore, which is a big positive. The swell is still small at 3ft, but it’s clean. The combined energy is 94, so it’s weak, but it’s rideable. This is the first day that’s even worth looking at. The offshore wind will be the key, making the most of what little there is. But still, it’s not going to be anything spectacular. On the 27th, we get a bit more. The afternoon shows a small but clean pulse of 2.3ft swell from the WSW, with a bit more energy (104). The wind is light and cross-offshore, and it’s about as good as it gets in this run. It’s an honest, small-wave day for the log.
The real standout, if you can call it that, is Thursday the 27th afternoon. It’s the best combination of any size, clean conditions, and light wind. With the swell direction from the WSW matching the break’s optimum, it’s worth a look. The water is 62.6°, which is just about normal for this time of year. The crowd factor at Whitesand Bay (Cornwall) is listed as “sometimes”, so you might have the place to yourself mid-week, but it’s a popular spot so be ready for a few others.
The second week is looking pretty hopeless for surf. The swell drops right off, and we just get a series of small, long-period pulses that are too weak and too far apart to do anything. The wind is also fresh and strong at times, which will just add more chop and mess. Don’t get your hopes up for that stretch. The 22nd morning and the 27th afternoon are your best bets, but they’re more about getting wet than getting barreled. Keep the expectations low, and you might have a bit of fun.
