6059-466: The subtropics or tropics. It has characteristically mild temperatures year-round, featuring the four seasons in the subtropics and no marked seasons in the tropics, the latter usually remaining mild to cool through most of the year. Subtropical highland climates under the Cfb classification usually have rainfall spread relatively evenly in all months of the year similar to most oceanic climates while climates under
6142-473: The subtropics. Japan receives over half of its rainfall from typhoons. The Mediterranean climate is a subtropical climate, usually found on the western side of continents, with a wet season in winter and a dry season in the summer. Regions with this type of climate include the rim lands of the Mediterranean Sea , southwestern Australia , parts of the west coast of South America around Santiago and
6225-641: The subtropics. Pest control of the crops is easier than in the tropics, due to the cooler winters. Tree ferns ( pteridophytes ) are grown in subtropical areas, as are dracaena and yucca , and trees in the Taxaceae . Apple , pear and pomegranate also grow well in the subtropics. The humid subtropical climate is a subtropical climate type characterized by hot, humid summers and generally mild winters. This climate can be found in northern Middle East , northern South Asia , northern Indochina , eastern Australia , southern and southeastern China , southern Japan ,
6308-537: The time transportation ceased in 1868, convicts outnumbered free settlers 9,700 to 7,300. In the 1890s, interstate immigration, resulting from a mining boom in the Goldfields region , resulted in a sharp population increase. Western Australia did not receive significant flows of immigrants from Britain, Ireland or elsewhere in the British Empire until the early 20th century. At that time, its local projects—such as
6391-473: The tiny settlement. Eucla has a semi-arid climate ( BSk ) with Mediterranean climate ( Csb ) tendencies. Summers are warm and dry, although mild by Australian outback standards. However, very hot days can occur, caused by hot northerly winds from the Great Victoria Desert . Winters are mild to cool with a rainfall peak. For a semi-desert climate the humidity is rather high all-year round, due to
6474-501: The warmest subtropical climates and the less warm tropical climates as defined by the Köppen-Geiger or Trewartha climate classifications. However Wladimir Köppen has distinguished the hot or subtropical and tropical (semi-)arid climates ( BWh or BSh ) having an average annual temperature greater than or equal to 18 °C (64.4 °F) from the cold or temperate (semi-)arid climates ( BWk or BSk ) whose annual temperature average
6557-417: The winter (dry season) the monsoon retreats, and the drier trade winds bring more stable airmass and often dry weather, and frequent sunny skies. Areas that have this type of subtropical climate include Australia, Southeast Asia, and parts of South America. In areas bounded by warm ocean like the southeastern United States and East Asia, tropical cyclones can contribute significantly to local rainfall within
6640-502: Was 49.8 °C (122 °F) on 19 December 2019, while the lowest was −2.2 °C (28 °F) on 20 June 1936. Eucla is the largest stopping point between Norseman and Penong for travellers along the Eyre Highway . It has a hotel and restaurant, a police station, a golf club (7 km (4 mi) to the north), a museum dedicated to the Old Telegraph Station, and a meteorological station. These, together with fishing, are
6723-433: Was abandoned, and a new townsite established about 4 km (2.5 mi) to the north and higher up on the escarpment. The ruins of the original telegraph station which still stand amongst the dunes are a local tourist attraction. Many of the pioneer farmers and telegraph operators were buried at Eucla, but as the sand dunes encroached onto their graves, some of the headstones and plaques were removed and can now be seen at
6806-552: Was proclaimed a township and gazetted in 1885, and reached its peak in the 1920s, prior to the construction of a new telegraph line further north alongside the Trans-Australian Railway in 1929. In the 1890s a rabbit plague passed through the area and ate much of the Delisser Sandhills ' dune vegetation, thus destabilising the dune system and causing large sand drifts to encroach on the townsite. The original town
6889-636: Was reported in the Perth Hills , as far north as Wongan Hills and as far east as Salmon Gums . However, even in the Stirling Range, snowfalls rarely exceed 5 cm (2 in) and rarely settle for more than one day. The highest observed temperature of 50.7 °C (123.3 °F) was recorded in Onslow on 13 January 2022. The lowest temperature recorded was −7.2 °C (19.0 °F) at Eyre Bird Observatory on 17 August 2008.
