Bossiney Haven Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s be straight with you – this 16-day window for Bossiney Haven is a tough one. The overall pattern is a long stretch of poor surf quality, with onshore winds and messy conditions dominating. The best bet is tucked away in the second week, but even that comes with a caveat.

Starting off, we’ve got nothing worth paddling out for. The first surf recommendation is a blank. From Wednesday the 5th of August right through to the morning of Wednesday the 12th of August, it’s just a run of poor surf. The swell is tiny, the wind is cross or cross-onshore, and the water is a touch warmer than normal for the time of year at 65°F, but that’s the only nice thing I can say. Energy levels are weak, barely cracking 100 (combined energy 290 down to 9), and the wave periods are short, mostly 6 to 8 seconds. It’s a frustrating start.

Then, around Wednesday the 12th of August morning, things finally shift. The combined energy hits 117 (moderate), and we get clean conditions with a light cross-offshore breeze. The swell is 3 ft from the west with a 10-second period – that’s a bit more groundswell character, which means better shape and longer gaps between sets. This carries into the afternoon, holding at 3 ft and clean. It’s not huge, but it’s the best-looking window in the whole run.

Thursday the 13th of August morning sees the swell push up to 4 ft from the west, period dropping to 8 seconds, but still clean with a cross-offshore breeze. Energy is now 219 (moderate). This is the standout. The west swell is coming from the optimum direction for this break, and the clean wind will make for proper lined-up waves. It’s going to be a bit more challenging for beginners at this size, but for anyone intermediate and up, this is the session to aim for.

Unfortunately, the afternoon of the 13th gets messier as the wind swings cross-shore and the swell builds to 5 ft with a period of 9 seconds. Energy hits 381 (strong), but the wind chops it up. Friday the 14th of August is a write-off with cross-onshore winds and lumpy conditions.

Now, here’s a glimmer for the second week. Saturday the 15th of August morning offers clean offshore winds, with a 2 ft west swell. Energy is low at 48, but it’s glassy-clean. The afternoon gets even better with a moderate offshore breeze and 3 ft swell. For a small-wave board, this could be a fun, uncrowded session. Bossiney Haven can get crowded sometimes, so the small size might keep the numbers down.

Sunday the 16th is a no-go with building swell and strong cross-onshore winds.

Monday the 17th of August morning brings a clean cross-offshore breeze, 4 ft west swell, and energy of 201 (moderate). The period is 8 seconds, so it’s a bit wind-swell-ish, but clean. That afternoon goes full offshore with a 3 ft swell – clean and lined up. This is another promising call, but it’s further out, so keep an eye on the forecast.

The rest of the window fades out with dropping swell and strong cross-shore winds. The combined energy dips back into the weak range. For the love of surfing, lock in those Wednesday 12th and Thursday 13th of August mornings, and keep an eye on Saturday 15th and Monday 17th for the smaller, cleaner windows.

Rusty.
