Bossiney Haven Surf Forecast and Surf Report

Alright, Rusty here again, switching to feet and degrees Fahrenheit.

Let’s be real: the next 16 days at Bossiney Haven are a long, flat stretch of frustration. There’s nothing that gets the heart pumping. The first half-decent chance doesn’t show up until Saturday, September 12th. Before that, it’s all cross-shore wind, lumpy chop, and sad little waves.

The water temp is 65°F, which is a touch warmer than usual for this time of year – a nice thought, but the waves aren’t cooperating.

Bossiney Haven is a sheltered little spot that needs a west swell, and we’re getting that direction, but the wind is the problem. Thursday the 3rd and Friday the 4th have waist-high swell (5ft to 7ft), but the wind is cross or cross-off, and the period is a short 8 seconds, so it’s all weak, lumpy junk. The combined energy on Friday morning hits a moderate 563, but the wave comment says it’s poor. Not worth it.

Saturday the 5th drops to 4ft to 3ft with a longer 10-second period, but the wind is still cross. Small, weak, bumpy. Energy is 294 in the morning.

Sunday the 6th has tiny 2ft west swell with 9 seconds, and finally some clean conditions in the afternoon with a moderate offshore from the SSE. But energy is only 54 – barely a ripple. You’d be lucky to get a ride.

Monday the 7th is the biggest swell – 7ft west groundswell with a long 13-second period, and massive energy of 1430 in the morning. That’s serious power. But the wind is cross-onshore from the NW, turning it into a choppy, closing-out mess. Only for experts, and even then it’s ugly. Kite surfers might have a field day.

The rest of the first week and into the second is more lumpy cross-shore wind and moderate energy. The gap of poor conditions runs from the 3rd all the way to the 12th.

Finally, on Saturday the 12th afternoon, a glimmer. A 3ft west swell with 10 seconds, cross-off wind from the WSW, and a gentle breeze. Energy is 220 – weak – but the conditions are clean and “surfable but very ordinary.” You might get a few grovelly ones.

Then Tuesday the 15th morning has glassy conditions with a 4ft west swell (9 seconds, 185 energy) and offshore wind from the ESE. Clean, but tiny. Wednesday the 16th is also glassy with 3ft waves and 10 seconds (131 energy). These are the “might as well be paddleboarding” days.

The last few days (17th and 18th) are back to fresh cross-shore wind and lumpy, with energy below 100. Not worth it.

Bottom line: no standouts. The cleanest, most rideable windows are Saturday the 12th afternoon or Tuesday the 15th morning. If you’re dying for a paddle, go then. Otherwise, save your energy. Forecasts can change, but this one’s a dud.
