Conditions at Katagai in May
May: Plenty of Swell, Scattered Wind Windows
May is a classic shoulder month: the swell direction is almost perfect, with SE, ESE, E and SSE waves dominating and average surf holding at 1.2m (4ft). However, wind and weather grow more complicated. Offshore flow drops to just 22 percent, and a persistent summer monsoon pattern brings SSW/SW winds and afternoon sea breezes that can ruin an otherwise clean lineup. Average water temp climbs to 17.1°C and air temps reach 18.4°C - spring wetsuits start to feel good - but the reward comes from chasing the early mornings, when lingering NW flow can still groom the easterly swell before the seabreeze kicks in.
