The average temperature in January, the area's coldest month, is 32.1 °F (0.1 °C). However temperatures in winter could for a few days be as low as 20 °F (−7 °C) and as high as 60 °F (16 °C). Spring and autumn are unpredictable, and can range from chilly to warm, although they are usually pleasantly mild with low humidity. Summers are typically hot and humid with a July average of 76.5 °F (24.7 °C). Nighttime conditions are often exacerbated by the urban heat island phenomenon, and temperatures exceed 90 °F (32 °C) on average of 18 days each summer and can exceed 104 °F (40 °C) every 4–6 years.
