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

and stretches down to the southern coast of Sydney, where it transitions into the cooler, oceanic climates. From Newcastle, New South Wales, Newcastle, approximately northeast of Sydney, the ''Cfa'' zone would extend to inland New South Wales, excluding the highland regions (which have an oceanic climate), stretching towards Dubbo to the northwest and Wagga Wagga to the south, ending at the New South Wales/Victoria (Australia), Victoria border (Albury–Wodonga). To note, these places would have characteristics of the semi-arid and/or Mediterranean climates. 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 Greater Western Sydney, western suburbs, where highs over are not uncommon. Frost is prevalent in the more inland areas of Sydney, such as Richmond, New South Wales, Richmond. Average annual rainfall in the Sydney region ranges between . There is usually a distinct summer rainfall maximum that becomes more pronounced moving northwards. 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 Australian east coast low, east coast lows forming to the north of a anticyclone, large high pressure system, there can be great variation in rainfall amounts from year to year as a result of these systems. As an example Lismore, New South Wales, Lismore which lies in the centre of this zone, the annual rainfall can range from less than in 1915 to more than in 1950.


Europe

As the continent does not have a large ocean to its east as the case in many other continents within the climate zone, humid subtropical climate in Europe is limited to relatively small areas on the margins of the Mediterranean and Black Sea basins. ''Cfa'' zones are generally transitional between the Mediterranean climate zones along the coast and oceanic and humid continental zones to the west and north where rainfall in the warmer months is too high for a Mediterranean classification, while temperatures (either in the summer and/or winter) are too warm to qualify as oceanic or humid continental. Humidity is not as high here as in other continents within this climatic zone. The Po Valley, in Northern Italy, including major cities such as Milan, Turin, Bologna, and Verona, has a humid subtropical climate, featuring hot, humid summers with frequent thunderstorms; winters are foggy, damp and chilly, with sudden bursts of frost. Some parts of the valley have a mild continental climate. Places along the shores of Lake Maggiore, Lake Lugano, Lake Como (Como and Verbania in Italy and Lugano in Switzerland) have a humid subtropical climate with a distinctive high amount of rainfall during summer. Due to recent warming, cities in the Pannonian Basin such as Belgrade, Novi Sad and Budapest, Hungary, are now just warm enough to be categorized as such. At 47th parallel north, 47°N, Budapest lies on the northern limit of the humid subtropical zone. The coastal areas in the northern half of the Adriatic Sea also fall within this climate zone. The cities include Trieste, Venice, and Rimini in Italy, Rijeka and Split, Croatia, Split in Croatia, Koper in Slovenia and Kotor in Montenegro. Other Southern European areas in the ''Cfa'' zone include the central valleys and coast of Catalonia of Girona and Barcelona in Spain, some on the north-east of Spain (Huesca), West Macedonia in Greece (Kozani), the Garonne, Garonne Valley (Toulouse) and Rhone, Rhone Valley (Valence (city), Valence) in France.

coast of Bulgaria (Varna, Bulgaria, Varna), coast of Romania (Constanta and Mamaia), Sochi, Russia and Crimea, have summers too warm (> in the warmest month) to qualify as oceanic, no freezing month, and enough summer precipitation and sometimes humid conditions, where they would be fit to be classed under ''Cfa'', though they closely border the Humid continental climate, humid continental zone. All these areas are subject to occasional, in some cases repeated snowfalls and freezes during winter. In Central Europe, a small area of humid subtropical climates are located in transitional areas between the oceanic and continental climates in areas where higher summer temperature do not quite qualify it for inclusion in the Oceanic climate schema (but, in the

, this type of climate is included in that typical of the other areas of central-west Europe, classified as Do -the Temperate Oceanic climate-) and mild winters do not allow their inclusion into continental climates. Average summer temperatures in areas of Europe with this climate are generally not as hot as most other subtropical zones around the world. In the Azores, some islands have this climate, with very mild and rainy winters (>) and no snowfall, warm summers (>) but with no dry season during the warmest period, which means that they can neither be classified as oceanic climate, oceanic, nor as Mediterranean climate, Mediterranean, only as humid subtropical, as with Corvo Island. In many other climate classification systems outside of the Köppen, most of these locations would not be included in the humid subtropical grouping. The higher summer precipitation and poleward flow of tropical air-masses in summer are not present in Europe as they are in eastern Australia or the southern United States.
