Conditions at Ikumi in October
October: The Window Opens Wide
October is statistically the best month for the combination of swell direction and period at Ikumi. The average wave period reaches 9.5s - the highest of the year - and the favourable ESE swell surges to 36.8 percent, with E adding 9.6 percent, ENE 2.5 percent, and NE 0.2 percent, for a massive 49.1 percent of swell from the optimal quadrant. Average height is 3ft (0.9m), but with such long periods, even the 2-5ft (0.5-1.5m) band becomes rideable and punchy. The downside is the wind: the NNE flow is the strongest of any month at 31.5 percent, and NE/ENE winds contribute another 19.7 percent, limiting the ideal wind percentage to just 17 percent. So October serves up the most promising waves, but they are frequently accompanied by onshore or cross-onshore winds. The trick is to wait for a north-westerly swing - which does occur about 10 percent of the time - and then the stars align. Water temperature is a pleasant 24.7°C, air 20.7°C, and precipitation has dropped to 5.68 mm/day. This is the month to watch the forecast closely.
