Humid subtropical climates generally have long, hot and humid summers with convective showers in summer and a peak seasonal rainfall in the hottest months. Winters are normally mild in the humid subtropics, and warm ocean currents normally are found in coastal areas with humid subtropical climates. This type of climate is normally located along leeward lower east coasts of continents such as in southeast and central Argentina, Uruguay and south of Brazil, the southeast portions of East Asia, the southern United States, South Africa, Ethiopia, and eastern Australia. In some areas with a humid subtropical climate (most notably southeast China and North India), there is an even sharper wet-dry season, called subtropical monsoon or Cwa. In these regions, winters are quite dry and summers have very heavy rainfall. Some Cwa areas in southern China reported more than 80% of annual precipitation in the 5 warmest months (southwest monsoon).
