Conditions at Choshi in November

November: Winter Monsoon Returns with Consistent Waves

November is one of the cleanest months of the year at Choshi. The ideal wind frequency jumps to 44%, second only to December, as the Siberian High rebuilds and the northwest winter monsoon kicks in. Average swell heights hold at 5ft (1.6m), with a solid 9.5s period. The directional spread still favours ENE/E/NE swells, which together account for over 50% of the observations, but important contributions from ESE/SE/S add variety. Winter lows are now marching across the North Pacific with regularity, and each one drags a cold front through Japan, creating the N/NW offshore flow that makes the south-facing beach line up. Water temperatures fall to 18.2°C, and the precipitation drops to 3.66 mm/day. The combination of well-organized groundswell, offshore monsoon winds, and moderate air temperatures makes November a prime month for Choshi.
