Conditions at Karmay in October
October: The North Atlantic Roars Back
October is the true autumn turning point. Average swell height climbs to 6.6ft (2.0m) and average period lengthens to 8.6s, with swell distribution broadening across W, WSW, SW, SSW, NW and WNW. The frequency of strong extratropical storms over the North Atlantic jumps, and Karmay's SW exposure starts to line up with a more regular supply of storm swell.
The wind picture is still messy: SSE, SE and S keep a lot of onshore/cross-shore energy in the water, and ideal offshore windows remain around 22%. But when the low pushes through and a cold northwesterly wraps into N/NE, the combination of fresh W/SW swell and clean offshore flow is electric. Water temperature has dropped to 12.6°C, air temps average 10.4°C, and precipitation rises to 5.26mm/day - a classic storm-surf month.
