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.

In July, Monobegawakakou offers relatively small but surfable conditions, with an average swell height of 0.7m and a decent period of 8.1s. The swell is most frequently from the ESE, SE, and SSE directions, contributing to the majority of rideable waves, though wave heights are generally modest—mostly in the 0.5-1m range, with occasional 1.5m+ days (around 3-5% of the time). The wind is a mixed bag, with only 11% of conditions being ideal (typically light offshore or cross-offshore). The worst wind direction is SW, bringing stronger onshore winds (20-50kph) that can ruin the surf, especially since this direction accounts for a significant portion of wind occurrences. Surfers should watch for windows when ESE/SE winds are lighter (0-20kph) to find cleaner waves. Overall, patience is key in July—expect smaller, fun-sized surf with occasional mid-period pulses, but be prepared for some blown-out days due to onshore SW winds.
