April: Spring Mix - Easterly Energy Meets South Swell
April turns the corner. The dominant swells shift from the W/NW to the E/SE quadrant, with E 9.4%, ESE 18.9%, SE 14.0% and SSE 9.8% making for a busy, mostly cross-shore sea state. More importantly for Omaezaki, the S/SSW/SW window delivers a healthy 27.6% of the total swell, and those south swells often hold the larger size classes: SSW has 2.1% at 1.5-2m and 1.2% at 2-2.5m, while SW and S chime in with solid mid-size energy. The average period reaches 7.8s, so wave quality is noticeably better.
Wind is the usual spoiler. E/ENE totals around 23.6%, WSW 10.1% and W/WNW 24.9%, meaning clean offshore windows are limited. Still, ideal wind sits at 18% and spring fronts can deliver crisp N/NNE post-frontal days. Air temps inch up to 15.7°C, rain increases to 6.21mm/day, and the water is 16.5°C. April is a mix of fun, rippable south swell and unavoidable skunk days.
