Cherry blossoms after a warm winter

Unfortunately, it is raining, but along the street called Sakura-dori (cherry blossom street) in front of our office in the center of Fukui City, cherry blossom trees are nearly in full bloom already. So they will be in full bloom as early as the beginning of next week.

It will be already April next week, so it's not surprising. This year, it was a record warm winter and we had almost no snow in Fukui, a heavy snowfall area. So I didn't feel like winter, but nevertheless, the cherry blossom trees did not bloom much earlier, one month or so than usual, and did only a few days earlier.

There may be a mechanism that even if the temperature rises, they wouldn't bloom simply. It's interesting.
