Conditions at Kitaizumi in August
August: Typhoon Alley
August remains a low-consistency month, but the stakes get higher. The average wave height rebounds to 1.0m (3ft), period reaches 8.6s, and the distribution is packed with ESE at 32.6 percent, SE at 26.3, E at 22.4 and ENE at 7.7. This is typhoon alley: tropical storms and typhoons spinning through the western Pacific can generate pulses of E/ESE swell in the 1.5-2.5m (5-8ft) range, with the data showing that 1.5-2m and 2-2.5m bands tick up compared to June and July. The catch is the wind. Ideal surf wind sits at only 31 percent, and SSE, SE and S winds dominate, putting an onshore bump on most of that storm swell.
Air temperatures average 24.0°C, water temperature reaches 23.2°C, and precipitation remains high at 4.33 mm/day. When the wind does swing offshore through the west, a passing typhoon to the south can turn Kitaizumi into the best wave of the summer. Otherwise, it is small, warm and soft.
