Alicante enjoys a Mediterranean climate with mild winter temperatures, warm to hot summers, and little rain concentrated in equinoctial periods. Scientists tend to classify the climate of Alicante region according to Köppen climate classification as semi-arid (BSk).On average the temperature ranges between 16.8 °C (62 °F) and 6.2 °C (43 °F) in January and between 30.6 °C (87 °F) and 20.4 °C(69 °F) in August, with an average annual temperature of 17.8 °C (64 °F). Daily oscillations in temperature are very small due to the influence of the sea, although occasional periods of Westerly wind can result in temperature ranges in excess of 15 °C (27 °F). Annual oscillations in temperature are also small meaning that winters are mild and summers are warm.
The average amount of rainfall is 336 mm (13.2 in) per year.
