Warm-summer Mediterranean Climate
Occasionally also termed “Cool-summer Mediterranean climate”, this subtype of the Mediterranean climate (Csb) is the less common form of the Mediterranean climate. As stated earlier, regions with this subtype of the Mediterranean climate experiences warm (but not hot) and dry summers, with no average monthly temperatures above 22.0 °C (71.6 °F) during its warmest month and an average in the coldest month between 18 to −3 °C (64 to 27 °F) or, in some applications, between 18 to 0 °C (64 to 32 °F). Also, at least four months must average above 10 °C (50 °F). Winters are rainy and can be mild to chilly. In a few instances, snow can fall on these areas. Precipitation is heavier during the colder months, but there are a number of clear sunny days even during the wetter seasons.
As stated earlier, in some instances, regions with this subtype of the Mediterranean climate closely resembles an Oceanic climate. Unlike typical Mediterranean climates, for the majority of the year, these regions experience generally cloudier and damper conditions. However, sunshine duration remains higher than in the Cfb areas, and during the summer months, these regions experience sunny, dry and warm conditions, where almost no rain falls. There is the legitimate threat of forest fires in these areas, in regions such as Galicia and the Pacific Northwest. Despite the fact that these climates are technically Csb climates, a number of scientists (and others) do not consider the climate “Mediterranean”, primarily because of the predominantly oceanic characteristics that these places exhibit. They are instead categorized as a form of an oceanic climate.
Csb climates are found in northwestern Iberia, coastal California and parts of the Pacific Northwest, central Chile, parts of southern Australia and sections of southwestern South Africa.
