Seasonal frost occurs when temperatures drop to the freezing point, causing moisture in the air or on surfaces to freeze. This phenomenon typically happens during the late fall, winter, and early spring months when nights are cooler. Frost can form on grass, leaves, and other surfaces, creating a layer of ice crystals. Frost is most common in regions with a temperate climate, where temperature fluctuations are significant. It can impact agriculture by damaging sensitive crops like tomatoes and flowers. Farmers often monitor weather forecasts to protect their plants from potential frost damage during vulnerable growing seasons.
