The Lowdown

Alright folks, Rusty here. Let’s be straight with you – this is a tough one.
Look, we’ve got a 16-day window for Bossiney Haven, but honestly, it’s a quiet stretch. The first surfable day with any real energy isn't until Monday the 12th of August, and even then, it's a small, clean affair. Before that, it’s a whole lot of nothing – Sunday the 9th and Monday the 10th are plain flat or just messy, with tiny 0.7ft to 1.0ft wind chop. The gap from the start until the 12th is a write-off.
The best of a very average bunch comes on Tuesday the 13th of August. Thursday morning the 13th sees a 3ft west-northwest swell with an 11-second period, which is a proper groundswell. The combined energy is moderate at 230 (moderate wave energy). Now, that period is long enough to get some shape, but for a sheltered spot like this, it might be a bit too straight for the beach. The wind is onshore from the north-northwest, so it’ll be a bit wonky. If you’re an expert looking for a challenge, it’s the stand-out, but it’s not clean.
The real hidden gem, and the only time I’d actually get excited, is Wednesday the 12th of August. The morning has a 2ft west swell with a 10-second period, but the energy is actually building to 94 (weak energy). The afternoon is where it’s at: glassy winds from the southeast, 2ft swell, and the same 10-second period. It’s tiny, but with glassy conditions and a bit of a W swell, it’ll be the most fun you’ll have. The water temperature is about average for the time of year.
Sunday the 23rd of August also shows a glassy morning with 2ft, but the swell period is a short 8 seconds, so don’t expect much push. It’s a long way out.
Forget the rest of the days. The wind is cross-on or onshore, the swell is small, and the setups are all showing poor surf conditions. The only real positive is that for a small, sheltered beach break, a glassy afternoon like Wednesday the 12th will be a lovely little session. Crowds are possible there, so get in early.
Stay patient, lads. It’s not a complete loss, but it’s a waiting game. Tuesday the 13th is for the brave, Wednesday the 12th is for the smart.
Rusty.
