March: Spring Transition - More South Swell, More Wind Variability
March begins the transition away from the winter pattern, with average swell height bumping up to 0.8m (2.6ft) and period to 8.1s. The swell roses show a healthy spread of south energy: SSE (12.2%), S (14.9%), SSW (17.2%) and SW (11.6%) account for 56% of the waves, giving Inamuragasaki excellent directional exposure. However, the wind regime becomes more fickle. Offshore N/NNE/NE/NNW flow still occurs 51% of the time, but onshore SSE, S, SSW and SW winds increase to roughly 27%, with SSW/SW breezes gusting into the 20-40kph range. That pushes the ideal surf window down to just 18%, though when a high-pressure ridge sets up to the north, mornings can deliver clean 2-3ft (0.6-0.9m) lines. Air temperatures warm to 6.8°C and precipitation climbs to 3.83 mm/day, while water temperature remains cold at 14.9°C. It's a month to pick your sessions.
