The climate of South West England is classed as oceanic (Cfb) according to the Köppen climate classification. The oceanic climate typically experiences cool winters with warmer summers and precipitation all year round, with more experienced in winter. Annual rainfall is about 1,000 millimetres (39 in) and up to 2,000 millimetres (79 in) on higher ground. Summer maxima averages range from 18 °C (64 °F) to 22 °C (72 °F) and winter minimum averages range from 1 °C (34 °F) to 4 °C (39 °F) across the south-west.
It is the second windiest area of the United Kingdom, the majority of winds coming from the south-west and north-east. Government organisations predict the region to rise in temperature and become the hottest region in the United Kingdom.
Inland areas of low altitude experience the least amount of precipitation. They experience the highest summer maxima temperatures, but winter minima are colder than the coast. Snowfalls are more frequent in comparison to the coast, but less so in comparison to higher ground. It experiences the lowest wind speeds and sunshine total in between that of the coast and the moors. The climate of inland areas is more noticeable the further north-east into the region.
In comparison to inland areas, the coast experiences high minimum temperatures, especially in winter, and it experiences slightly lower maximum temperatures during the summer. Rainfall is the lowest at the coast and snowfall is rarer than the rest of the region. Coastal areas are the windiest parts of the peninsula and they receive the most sunshine. The general coastal climate is more typical the further south-west into the region.
Areas of moorland inland such as: Bodmin Moor, Dartmoor and Exmoor experience lower temperatures and more precipitation than the rest of the southwest (approximately twice as much rainfall as lowland areas), because of their high altitude. Both of these factors also cause it to experience the highest levels of snowfall and the lowest levels of sunshine. Exposed areas of the moors are windier than lowlands and can be almost as windy as the coast.
