Conditions at Mira in January
January: Peak Winter Groundswell and Clean Offshore Windows
January is peak winter at Mira. The average swell height checks in at 8ft (2.5m) with a 12.9s period, putting this month firmly in the powerful, long-period groundswell range. WNW and NW swells together account for over 40 percent of all incoming wave energy, and the broader west-northwest window supplies the west-facing beach with consistent, hard-punching sets. Most waves sit in the 1.5-2.5m range, right at the top end of pumping, and occasional pulses beyond 8ft (2.5m) keep things serious. What makes January extra special is the wind: with the Icelandic Low driving storms across the Atlantic and high pressure often parked to the northeast, offshore E/SE wind blows often enough to give a 49 percent ideal-surf-wind rating. Water temp is 13.8C (57F), air averages 10.2C (50F), and rainfall runs near 3.93mm/day, so bring the winter rubber and a good rain jacket. When a clean WNW groundswell meets that offshore breeze, Mira is firing.
