Weather in Alicante is “muy caliente” for most of the year, especially in summer. While it is true that the winter season cools off a bit, the average low is 43°F / 6.3 °C and the average high is 63°F / 17.0 °C. In the hot summers the temperature can reach between and 21.2 °C (70 °F) and 30.8 °C (87 °F). This semi-arid classified region has moderate rain, and is actually more influenced in temperature change by the nearby sea. However, rainfall averages 311 mm per year. The months predicted to have the most rain, including torrential rains, are September and October. Flooding is a recurring problem for some parts of Alicante, as the cold drop change in weather pattern can cause 200mm of rain to drop in as little as a day. Strong west winds do occasionally cause fluctuations in temperature. For the most part, the region stays consistent with its hot summers and mild winters—precisely why many vacationers used to icy winters enjoy the region. Only 37 rainy days are counted on average in this relatively dry city.
While blazing hot temperatures are not common, it’s not unheard of for the summer to reach triple digits. A temperature of 41.4 °C (107 °F) was recorded on July 4, 1994. The coldest day was back on February 12, 1956 at 4.6 °C (24 °F). The worst flood occurred as recently as 1997 when a startling 270.2 mm of rain fell within just six hours.
