The Lowdown
Alright folks, Rusty here. Let's be honest, looking at this stretch ahead, it’s a bit of a heartbreaker. We’ve got a long, long run of poor conditions before anything worthwhile shows up. We’re looking at a real drought for waves, so if you’re keen, you’ll need to be patient.
Right off the bat, through this week and into the next, it’s all pretty mushy and junky. The swell is small and mostly short-period, and that’s if we even get any. We’re talking ankle-biters at best, with a lot of onshore and cross-shore breeze messing up what little there is. The energy is weak too, with combined values in the low double digits to just over 200. The wind is constantly on it, making things choppy and lumpy, especially from the 18th to the 20th when it picks up a bit. The 22nd sees a bit of a bump in energy to 63 but it’s a fresh, lumpy cross-onshore, so it’s not doing us any favors. The 24th gets blown out with a fresh breeze hitting 22 mph and waves around 3.9ft but it’s all over the place. For us, that’s just not surf, that’s a washing machine.
There is a tiny glimmer of hope for cleanliness on the morning of the 27th, with a light cross-offshore breeze making things look clean at Bossiney Haven, but the swell is a non-event – 1.3ft at 7 seconds with only 18 in the energy reading. It’s clean, but you’d be struggling to get wet and do much. That’s a session for the rocks and the view, not for the board.
Then, it looks like the tap finally turns on. The first real standout, and it's a week and a half away, is on the morning of Friday, the 28th of August. This is the one to circle. Bossiney Haven (North Cornwall) is looking at a proper pulse of west swell, with a solid 6.9ft on offer. The period is a clean 10 seconds, so there’s some proper push behind it, and the energy reading jumps right up to 799, which is strong. But the best part is the light southerly offshore wind. That’s going to groom it into clean, lined-up waves. This is the standout on offer, no question. It’s a big jump in size from what we’ve seen, so we can expect some proper waves. It will be too much for beginners, for sure, but for the rest of us, it’s on.
The afternoon of that Friday still has a decent 4.6ft of west swell, but the wind swings more cross-off and the energy drops to 318. It’s still surfable, but the morning is definitely the window to grab. The following Saturday morning (29th) has a moderate offshore breeze with 3.3ft of swell, but it’s dropping and the energy falls away to 137. Still, it might be worth a look if you missed the boat on Friday.
Beyond that, it fades back down. The last week is all smaller and weaker again, mostly poor with a lingering cross-shore or onshore wind. The water temperature, given the long gap and being the first spot I mentioned, is looking about average for this time of year, which is a bit of a comfort while we wait out the flat spell. It’s a long haul, but that Friday morning of the 28th looks like it’s going to make it all worth it. Get your gear ready for it.
