Bossiney Haven Surf Forecast and Surf Report

Alright, Rusty here. Let’s size up Bossiney Haven for the next couple weeks.

Honestly, it’s a quiet spell. The first decent window doesn’t show up until 18 August, so expect a solid week of nothing much. That’s a long lull.

From the 10th to the 17th, it’s all small, choppy, and mostly blown out. Swells run from 0.7ft to about 4ft, but the wind is nearly always on it or cross-onshore, and the energy is weak. A few glassy moments on the 11th afternoon give you a clean 1.0ft wave with an 8-second period, but it’s barely a knee-high ripple. Not worth the hassle. Energy values are in the 20s, 30s, and 40s – that’s feeble. The 13th and 14th show a bit more push, with waves around 3ft and periods of 10-11 seconds, energy hitting 184 and 202, but winds stay 15-20 km/h onshore or cross-onshore, making it choppy and messy.

18 August is the first real glimmer. Tuesday morning sees a clean, cross-off breeze out of the SW at 10 km/h, with a 3ft swell from the WNW, 8-second period, and energy of 113. That’s moderate energy, and the near-flat conditions could give you a few clean little waves – ideal for the beginners this spot is known for. It’s small but tidy. The afternoon gets a bit lumpy, but the morning is the clear winner.

19 August also offers a glassy morning: 3ft from the W, 8-second period, NNW breeze at just 5 km/h, energy at 91. Weak but clean as a whistle. And by 21 August afternoon, another glassy spell: 2ft swell from the W at 10 seconds, ESE 5 km/h, energy at 87. That longer period might give a slightly better shape, but still tiny.

The standout across the whole 16 days is that Tuesday 18 August morning. It’s not big, but with the wind dropping out and a little push in the swell, it’s your best chance at a proper clean session. The 19 August morning is a close second for pure glass. Beyond that, it’s mostly waiting on the next change.

Water temp – not given for the first break, but it's typical late-summer stuff around here.
