Monobegawakakou - surf spot statistics

Monobegawakakou in Japan offers a mix of conditions throughout the year, with the best surfing opportunities typically found in the late summer and autumn months. The spot is predominantly windswell-driven, with ground swells remaining relatively low year-round, peaking in August and September at 16%. Wind conditions are challenging most of the year, with bad winds prevailing 80-90% of the time across all months. However, the period from September to November sees a slight improvement, with good wind conditions reaching up to 17-20%. During these months, the swell consistency also improves, with wind swell percentages staying above 56%, and no-swell days dropping to 23-29%. The mean swell size hovers around 0.7-0.8m, with slightly larger waves in March, April, September, October, and November. While summer months like August and September bring higher ground swell contributions, autumn (September to November) stands out as the most reliable window due to better wind conditions and a decent balance of swell presence. Early spring (March-April) also offers reasonable swell activity, but unfavorable winds remain a limiting factor. Winter months suffer from inconsistent swells and particularly poor wind conditions, making them less ideal for surfing. Overall, dedicated surfers should focus on September to November for the best combination of swell consistency and marginally better wind conditions.

October at Monobegawakakou offers relatively small but surfable conditions, with an average swell height of 0.8m and a decent period of 7.9s. The dominant swell directions are ESE (14.37% of waves in the 0.5-1m range) and SE (8.00% in the 0.5-1m range), providing consistent, albeit modest, wave energy. Larger waves (1.5-2m) are rare but do occur, primarily from NNE, NE, and SE directions. Wind conditions are less favorable, with only 20% of the time offering ideal offshore or light cross-shore winds. The most problematic winds come from NNE and NE, which are strong (10-30kph) and onshore, potentially creating choppy or blown-out conditions. SW winds also appear occasionally but are less consistent. For experienced surfers, the spot can work on days with ESE/SE swell and lighter winds, but expect mostly smaller, softer waves with limited power. Bigger days are rare and require a well-timed swell.
