Conditions at Ikumi in May
May: The South Swell Overshadows the East
May sees the summer monsoon pattern start to take hold. The ideal wind percentage rises to 35 percent, with offshore SW (9.6 percent), WSW (7.5 percent), and W (7.2 percent) flows becoming prominent, and a weak onshore NE/ENE component. However, the swell direction is now heavily biased to the south: SE (34.4 percent), SSE (26.5 percent), and S (16.0 percent) account for over three-quarters of the total. The favourable NE-ESE quadrant falls to just 15.6 percent, meaning Ikumi is getting mostly side-shore-south swell that wraps poorly onto its east-facing sand. Average height is 2.6ft (0.8m) and the period shortens to 7.7s, so the waves are small, soft, and intermittently bumpy. The water warms to 19.3°C and air to 19.7°C, but the rainy season is approaching (6.07 mm/day). Still, the increasing frequency of offshore winds means that when an ESE pulse sneaks in, the beach can offer fun, rippable waves.
