Conditions at Katahama in February
February: Still Winter, Slightly More East
February continues the winter pattern, with offshore winds from W (29.0%) and WNW (25.3%) still ruling the roost. The ideal wind percentage ticks up to 26%, and the average swell height holds at 1.3m (4ft). The swell direction begins a subtle shift: E (10.0%) and ESE (5.8%) increase their presence, bringing the total optimal swell coverage to 22.2% - still only about one in five days. The average period remains short at 6.8s, so the prevailing WNW/W swell still struggles to produce quality waves on the ESE-facing beach. The real gem of February is the occasional E/ESE groundswell that slips in under the strong offshore flow, yielding clean, punchy peaks on a perfectly groomed sea surface. Water temperature drops to the seasonal minimum of 14.6°C, air temps average 9.5°C, and precipitation rises slightly to 3.26 mm/day.
