That's because the flowers will come earlier if temperatures rise quickly in spring.
因为如果气温在春季快速上升,樱花就会提早盛开。
Conversely, if temperatures in the autumn and winter period are higher than usual, the blooms can end up being delayed.
相反,如果此前的秋冬两季气温比平时高,樱花的开放时间会推迟。
Extreme weather can affect the trees too, with unusual patterns in 2018 prompting some blossoms to appear in October, well before the usual season.
极端天气也会影响樱树。2018年不寻常的气候类型导致一些樱花在10月开放,比平时提早太多。
In general, blooms begin as early as March in southern Kyushu and appear as late as May in northernmost Hokkaido.
一般来讲,日本南部九州的樱花早在三月就开放了,而在最北部的北海道,樱花要到五月才开放。
In a bid to improve its forecasts, some outfits have started crowdsourcing data, including Weathernews, a firm in Chiba near Tokyo.
为提高预测准确性,一些机构开始通过众包的方式收集数据,比如,东京附近千叶市的天气资讯公司。
It relies on photos of buds sent in regularly by 10,000 citizens across the country who are registered on the company's website and app.
