Basilicata's climate owes much to the region's position itself under the influence of the three adjacent seas (Tyrrhenian, Adriatic and Ionian) and to the region's particularly tormented orography, with the mountain ranges never aligned in the same direction. In fact, despite their southern latitude many zones have rather low annual average temperatures: low winter temperatures, falling below zero at higher altitudes, can produce harsh winters while summers are relatively warm with significant variations in temperature. Temperatures rise significantly, especially in the summer months, as one goes towards Matera and the Ionian coast.
