Time for Nantong to enter Mei in 2022
Because the temperature in each region is different, the entry and exit time of plum blossoms in 2022 is also different. However, plum blossoms generally enter plum in mid-June, and bloom in the first half of July, lasting about 20 days. However, there are also cases where plum blossoms recruit late and leave late. For example, in the Meiyu area in 2020, plum blossoms enter the plum blossom early and leave the plum blossom late, lasting for a long time. At that time, Zhejiang officially entered the rainy season at the end of May, ten days earlier than before.
Generally speaking, the rainy season in 2022 will start in early June and end in early July, lasting about 20 days. It is expected that around June 10, plum blossoms will officially enter all places, and the plum blossom time will be in mid-July. When the rainy season comes, we must pay attention to things at home, check more and don't get moldy.
