The boats (hydrofoil) running between Kagoshima and Yakushima (nice tropical island, UNESCO World Heritage) can be cancelled in case of bad weather. When you have scheduled all the stops of your route, it can be quite stressful (you go to the other side of the planet… and you can finally not reach your destination, and you have reserved your accommodation and you have already planned to leave on a given day).
I gathered the cancellation announcements for the year 2014, and here are the number of days having cancelled boats (it does not tell how many boats have been cancelled for each day, though):
- January: 1
- February: 5
- March: 5
- April: 2
- May: 0
- June: 0
- July: 5
- August: 6
- September: 0
- October: 8
- November: 1
- December: 4
