Snow in Amanohashidate in March?

I am planning to drive from Osaka to Amanohashidate around 26 March. I am not sure if there will be snow in the area...will snow tires be required for the drive?

Very unlikely.

Now checked the observation record of the past 30 years at JMA,

but it was only 5cm in 1988 and 1cm in 2005, so the possibility is not "zero".

It is not late to decide after watching weekly weather forecast(週間天気) of Miyazu(宮津).

This local site also has weather forecast(not for weekly) and Live Cam.

Thanks everyone for your replies. I need to book a rental car so I need to decide early if I want to reserve one that is equipped with snow tires.
