South Florida/Miami metropolitan area has a tropical climate, similar to the climate found in much of the Caribbean. It is the only metropolitan area in the 48 contiguous states that falls under that category. More specifically, it generally has a tropical monsoon climate (Köppen climate classification, "Am"). The South Florida metropolis sees most of its rain in the summer (wet season) and is quite dry in the winter (dry season). The wet season, which is hot and humid, lasts from May to October, when daily thunderstorms and passing weak tropical lows bring downpours during the late afternoon. The dry season often starts in late October and runs through late April. During the height of the dry season from February through April, South Florida is often very dry, and often brush fires and water restrictions are an issue. At times cold fronts can make it all the way down to South Florida and provide some modest rainfall in the dry season. The hurricane season largely coincides with the wet season.
