  South Africa has a generally temperate climate because it is surrounded by the Atlantic and Indian Oceans on three sides, because it is located in the climatically milder Southern Hemisphere, and because its average elevation rises steadily toward the north (toward the equator) and further inland. This varied topography and oceanic influence result in a great variety of climatic zones. The climatic zones range from the extreme desert of the southern Namib in the farthest northwest to the lush subtropical climate in the east along the border with Mozambique and the Indian Ocean. Winters in South Africa occur between June and August. The extreme southwest has a climate similar to that of the Mediterranean with wet winters and hot, dry summers, hosting the famous fynbos biome of shrubland and thicket. This area produces much of the wine in South Africa and is known for its wind, which blows intermittently almost all year. The severity of this wind made passing around the Cape of Good Hope particularly treacherous for sailors, causing many shipwrecks. Further east on the south coast, rainfall is distributed more evenly throughout the year, producing a green landscape. The annual rainfall increases south of the Lowveld, especially near the coast, which is subtropical. The Free State is particularly flat because it lies centrally on the high plateau. North of the Vaal River, the Highveld becomes better watered and does not experience subtropical extremes of heat. Johannesburg, in the centre of the Highveld, is at 1,740 m (5,709 ft) above sea level and receives an annual rainfall of 760 mm (29.9 in). Winters in this region are cold, although snow is rare.
  
  The coldest place on mainland South Africa is Buffelsfontein in the Eastern Cape, where a temperature of −20.1 °C (−4.2 °F) was recorded in 2013. The Prince Edward Islands have colder average annual temperatures, but Buffelsfontein has colder extremes. The deep interior of mainland South Africa has the hottest temperatures: a temperature of 51.7 °C (125.06 °F) was recorded in 1948 in the Northern Cape Kalahari near Upington, but this temperature is unofficial and was not recorded with standard equipment; the official highest temperature is 48.8 °C (119.84 °F) at Vioolsdrif in January 1993.
  
  Climate change in South Africa is leading to increased temperatures and rainfall variability. Extreme weather events are becoming more prominent. This is a critical concern for South Africans as climate change will affect the overall status and wellbeing of the country, for example with regards to water resources. Speedy environmental changes are resulting in clear effects on the community and environmental level in different ways and aspects, starting with air quality, to temperature and weather patterns, reaching out to food security and disease burden. According to computer-generated climate modelling produced by the South African National Biodiversity Institute, parts of southern Africa will see an increase in temperature by about 1 °C (1.8 °F) along the coast to more than 4 °C (7.2 °F) in the already hot hinterland such as the Northern Cape in late spring and summertime by 2050. The Cape Floral Region is predicted to be hit very hard by climate change. Drought, increased intensity and frequency of fire, and climbing temperatures are expected to push many rare species towards extinction. South Africa has published two national climate change reports in 2011 and 2016. South Africa contributes considerable carbon dioxide emissions, being the 14th largest emitter of carbon dioxide, primarily from its heavy reliance on coal and oil for energy production. As part of its international commitments, South Africa has pledged to peak emissions between 2020 and 2025.
