The Lowdown
Alright folks, Rusty here. Let’s walk through what’s brewing for Bossiney Haven over the next couple weeks. I’ll cut it plain – it’s a slow start.
We’ve got a long stretch of flat or messy conditions kicking things off. For over a week and a half, the swell is small and the wind just won’t cooperate. It’s not until the tail end of the window that something promising appears.
Day by day: Friday the 11th and Saturday the 12th are a total washout – tiny, choppy surf with poor energy. Sunday the 13th brings a bump in energy (combined swell energy of 417, moderate) and clean cross-off winds, but it’s only a marginal call. Monday the 14th is small, Tuesday the 15th and Wednesday the 16th get lumpy with cross-on winds. Thursday the 17th drops to weak energy. It stays very ordinary through the 22nd, with just a few cleaner moments on small waves.
The first real standout pops up Friday the 25th of September. That morning we have a moderate offshore breeze from the SSW, a 1.2m W swell with a long 13-second period, and combined energy of 480 (moderate). That’s real groundswell. The water temperature is a touch warmer than normal for the time of year, but that’s secondary – the surf is the story. Clean, lined up, and with that long period, this sheltered spot will be well worth the wait.
Through the middle of the window, with those strong cross-onshore winds and lumpy conditions around the 15th and 16th, kite surfers might get more out of it than paddle surfers.
The one to circle: Friday 25th September morning. Offshore wind, solid groundswell – that’s your session.
Rusty, signing off. See you in the water.
