May is the rainiest month of the year in Kentucky, along with the highest number of storms. The precipitation registers in the range of 5" (127mm) to 6" (152mm), with occasional rainstorms and hailstorms that cause local disruptions. Day temperatures are in the average range of 74°F (23.3°C) to 81°F (27.2°C), while the nights are mild between 49°F (9.4°C) to 57°F (13.9°C). The snow disappears from the ground, even in the coldest areas. Late spring is prone to tornadoes and thunderstorms. The wet periods, however, do not mask the sun for extended periods, and bright sunshine basks the land. Wear jackets that comfortably withstand the rain when exploring outdoors. Blackberry Winter is a cold spell that occurs when the blackberries bloom. Breathtaking views of nature are at its best. Boating and fishing are popular activities as is relaxing on the lake shores. Evenings witness picturesque sunsets on the fabulous lakesides. Beware of stormy and wet weather as well as a continental polar air mass visit in May in Kentucky.
