霜降是中国传统二十四节气（the 24 traditional Chinese solar terms）中的第十八个节气，英文表达为Frost's Descent。霜降期间，气候由凉向寒过渡，所以霜降的来临意味着“寒秋”的开始。

Frost's Descent is the last solar term of autumn, during which time the weather becomes much colder than before and frost begins to appear.

霜降是秋季的最后一个节气，在此期间，天气相较之前会冷得多，寒霜开始出现了。

地面上的水汽遇冷凝结成白色冰晶，这就是所说的“霜”（frost）。这段时间里，植物慢慢失去生机，大地变得萧条，所以民间有“霜降杀百草”的说法。
