The Lowdown
Alright folks, Rusty here. Let’s take a good, hard look at what’s on offer for Bossiney Haven over the next couple of weeks.
Right off the bat, I gotta be straight with you: this is a quiet stretch. There’s a big gap of nothing special at the start. The first couple of days are just flat or messy, with cross-shore winds and weak, choppy energy. That 5 ft of WNW swell on Tuesday morning the 18th looks promising on paper, but it’s got a short period of just 7 seconds and a cross wind that’s messing it up. The water is sitting at 66°, which is a solid 4° warmer than usual for this time of year – feels like a bath, but the surf quality is a letdown.
We get a bit of a pulse on Thursday the 20th, with the swell hitting 6 ft and the combined energy reading 456 – that’s moderate to strong energy. But the wind is cross-onshore and choppy, so it’s not the clean, lined-up waves we want. This spot is sheltered, so it needs a clean window to really shine. Honestly, for the first week, the setup looks more interesting for a kite surfer than a paddle surfer.
Now, hold on. There’s a glimmer of hope. On Tuesday the 25th, we’ve got a 6 ft WSW swell rolling in with a combined energy of 537. The wind is a clean offshore from the SSE, and the period is 9 seconds – that’s a decent groundswell pulse. This is the standout of the whole outlook. The waves will be well-shaped and clean, but keep in mind, at 6 ft it’s pushing the limit for beginners. For the experienced crew, it’s a solid session. The crowd here is listed as "sometimes", so it might get a few heads, but it’s worth the paddle.
After that, it drops off again. Thursday the 27th morning is glassy with a 3 ft swell, but it’s weak and short-lived. The following days are small and mostly clean, but nothing with enough push to get excited about. The first week of September sees a little bump of 5 ft on Tuesday the 1st, but with a short period of 6 seconds, it’s just weak, windswell slop.
So, the call is: if you’re itching for a wave, focus everything on Tuesday the 25th. That’s the best chance for a proper, clean session. The rest of the run is a write-off for anyone who wants to actually get a decent ride.
Stay keen, and keep an eye on the charts – things can change.
Rusty.
