This climate features mean temperature in the coldest month between (or ) and and mean temperature in the warmest month or higher. However, while some climatologists have opted to describe this climate type as a "humid subtropical climate", Köppen himself never used this term. The humid subtropical climate classification was officially created under the Trewartha climate classification. In this classification, climates are termed humid subtropical when they have at least 8 months with a mean temperature above . While many subtropical climates tend to be located at or near coastal locations, in some cases, they extend inland, most notably in

, where they exhibit more pronounced seasonal variations and sharper contrasts between summer and winter, as part of a gradient between the hotter tropical climates of the southern coasts and the colder continental climates to the north and further inland. As such, the climate can be said to exhibit somewhat different features depending on whether it is found inland, or in a maritime position.


Characteristics

In a humid subtropical climate, summers are typically long, hot and humid. Monthly mean summer temperatures are normally between . A deep current of tropical air dominates the humid subtropics at the time of high sun, and daily intense (but brief) convective thundershowers are common. Summer high temperatures are typically in the high 20s to mid-30s °C (80s or 90s °F), while overnight lows in the summer are typically in the lower 20s °C (70s °F). Monthly mean temperatures in winter are often mild, typically averaging . Daytime highs in winter normally are in the range, while overnight lows are from , though the poleward boundaries of this climate feature colder temperatures, possibly below freezing. Rainfall often shows a summer peak especially where

that have fronts that reach down into subtropical latitudes. However, many subtropical climates such as southeast Asia and Florida in the United States have very dry winters, with frequent brush fires and water shortages. Under the Holdridge life zones classification, the subtropical climates have a biotemperature between the frost or critical temperature line, (depending on locations in the world) and , and these climates are humid (or even perhumid or superhumid) when the potential evapotranspiration (PET) ratio (= PET / Precipitation) is less than 1. In the Holdridge classification, the humid subtropical climates coincide more or less with the warmest ''Cfa'' and ''Cwa'' climates and the less warm humid tropical "Köppen" climates (''Aw'', ''Am'' and ''Af'').

lie just north of South Florida and around southern coastal Texas. Cities at the southernmost limits, such as Tampa and Orlando and along the Texas coast around Corpus Christi down toward Brownsville generally feature warm weather year-round and minimal temperature differences between seasons. In contrast, cities at the northernmost limits of the climate zone such as New York, Philadelphia and Louisville feature hot, humid summers and chilly winters. These areas have average winter temperatures at the coldest limit of climates classed as humid subtropical. Snowfall varies greatly in this climate zone. In locations at the southern limits of this zone and areas around the Gulf Coast, cities such as Orlando, Tampa, Houston, New Orleans, and Savannah rarely see snowfall, which occurs, at most, a few times per generation.

Furthermore, the inland ''Cfa'' climates generally have drier summers, or at least summers with low humidity. Extreme heat is more often experienced in Sydney than in other large cities in Australia's ''Cfa'' zone, especially in the western suburbs, where highs over are not uncommon. Frost is prevalent in the more inland areas of Sydney, such as

In Brisbane, the wettest month (February) receives five times the rainfall of the driest month (September). Temperatures are very warm to hot but are not excessive: the average maximum in February is usually around and in July around . Frosts are extremely rare except at higher elevations, but temperatures over are not common on the coast. North of the ''Cfa'' climate zone there is a zone centred upon Rockhampton which extends north to the Köppen ''Cwa'' classified climate zone of the Atherton Tablelands region. This region has a very pronounced dry winter period, with often negligible rainfall between June and October. Winter temperatures generally only fall slightly below , which would classify the region as a tropical savanna, or ''Aw'', climate. Annual rainfall within Australia's humid subtropical climate zone can reach as high as in coastal locations and is generally or above. The most intense 2-3 day rainfall periods that occur in this coastal zone however are the outcome of
