Conditions at Sendai in February
February: Cold Water, Strong Offshore Flow and Building North Pacific Swell
February matches January in size and period, with an average swell height of 3ft (1.0m), a 9.3s period, and ideal wind 47% of the time. ENE swell is the standout direction at 14.1%, followed by E (10.8%) and ESE (8.8%). These are the long-fetch storm swells that make Sendai work in winter. The wind tables still favour the offshore WNW/NW quadrant, with combined WNW and NW winds near 51%, so cold, clean conditions remain frequent. The water temp hits the annual minimum at 7.8°C, while the air averages 1.2°C, so thick rubber and wind protection are mandatory. When the swell and wind align, expect powerful, mid-period lines with occasional 5-6ft (1.5-1.8m) bombs from the E/ENE swell window.
