Charleston has a four-season humid subtropical climate (Köppen Cfa) with continental climate (Dfa) elements. Especially in winter, Charleston's average temperatures are warmer than the rest of the state, due to the city being west of the higher elevations. Spring is the most unpredictable season, and spring-like weather usually arrives in late March or early April. From the beginning of March through early May, temperatures can vary considerably and it is not unusual at this time for day-to-day temperature fluctuations to exceed 20 °F (11 °C). Temperatures warm up considerably in late May, with warm summer-like days. Summer is warm to hot, with 23 days of highs at or above 90 °F (32 °C), sometimes reaching 95 °F (35 °C), often accompanied by high humidity. Autumn features crisp evenings that warm quickly to mild to warm afternoons. Winters are chilly, with a January daily average of 34.4 °F (1.3 °C), and with a mean of 16 days with maxima at or below the freezing mark. Snowfall generally occurs from late November to early April, with the heaviest period being January and February. However, major snowstorms of more than 10 inches (25 cm) are rare. The area averages about 3.5 inches (89 mm) of precipitation each month. Thunderstorms are frequent during the late spring and throughout the summer, and occasionally they can be quite severe, producing the rare tornado.
