The best time to visit
On Shikoku, the rainy season begins in early June. Accordingly, the most rainy days of the year occur in June (17 days) and July (17 days).
In midsummer, July and August, it gets very hot, with temperatures well over 85 °F / 30 °C during the day. And the temperatures also remain high at night. In these months it is too hot for demanding pilgrimages. Tropical cyclones (typhoons) hit Shikoku particularly frequently in these high summer months.
It can get quite cold in December, January and February. Snowfall can also occur on the higher parts of the pilgrimage route.
The Shikoku Pilgrimage Trail can basically be walked all year round, but temperatures are most pleasant in spring and autumn.
The cherry trees blossom on Shikoku in the second half of March to early April, with yearly variations due to the climate.
Many of Shikoku’s temples are famous for the magnificent colouring of the maple leaves in late November.
These are also the times when the vast majority of pilgrims are on their way.
The Golden Week
During the “Golden Week” (ゴールデンウィーク), four fixed holidays are supplemented with weekends and bridge days to form a longer period. During this time, most Japanese take time off to travel or visit family. It is advisable to take this into account when planning and to book accommodation as early as possible.
