Conditions at Belmar in October
October: The North Atlantic Roars Back to Life
October is when the North Atlantic truly switches on along the Jersey coast. Average swell height climbs to 4ft (1.2m) and period strengthens to 7.7s, while a more active storm track reintroduces consistent, organized east-southeast groundswells. The favorable ENE/E/ESE/SE quadrant totals 48% of the spectrum, led by ESE (15%), E (14%), and SE (11%). With water temp still comfortable at 18.0°C and air temps averaging 15.5°C, it is arguably the most pleasant time of year to be in the water. Offshore winds blow an ideal direction 40% of the time, with WNW/NW directions increasing as cold fronts begin their regular march. This is the true turning point: expect longer-period pulses, cleaner conditions, and a distinct shift from summer lull to autumn power.
