In summer, the ocean acts like a kind of natural air conditioner: on the coast, for example in Santa Monica, at the Los Angeles International Airport or in Long Beach, daytime temperatures are quite cool, and remain around 24/25 ☌ (75/77 ☏) they are higher, but they don't reach 30 ☌ (86 ☏), in the central districts of the city (see the table above), although they slightly exceed this value in the areas located further from the sea (see Pasadena), not to mention the eastern areas, which are closer to the desert. Summer, from July to September, is hot and sunny. The phenomenon is due to the contrast between the sea, which is still cold, and the mainland, which is getting increasingly warmer. In June, and sometimes in May, the phenomenon called " June gloom" can occur in the morning: this is a kind of cloudy and damp weather, sometimes foggy, accompanied by a sort of drizzle, which is formed on the sea and later can invade the mainland and therefore the area of Los Angeles. Spring, from April to June, is pleasantly warm and sunny. However, to the north of the city, the San Gabriel Mountains, whose highest peak is Mount San Antonio, 3,067 meters (10,062 feet) high, are quite often covered with snow, and offer a nice view on the horizon.Īs mentioned, the Santa Ana can sometimes blow also in winter, and it's able to the temperature to about 25 ☌ (77 ☏) or above.

The rains occur in short periods of bad weather, and are generally not abundant, although, as mentioned, there can sometimes be waves of bad weather more intense than usual. However, after the rare cold air outbreaks, the night temperature can approach freezing (0 ☌ or 32 ☏).

There are many pleasant and sunny days, with daytime temperatures around 20 ☌ (68 ☏). Winter, from December to March, is a very mild and spring-like season. Sometimes, the Santa Ana winds can spread fires. San Fernando Valley (see San Fernando, Van Nuys, Burbank, Glendale), north-west of the city, being closed between the hills, is even hotter, so much so that the highest records are about 46/47 ☌ (115/117 ☏). The highest recorded temperature was measured on September 27, 2010, with 44.5 ☌ (112 ☏) in the city center and 40.5 ☌ (104.5 ☏) at the airport, which is located on the coast. Heat waves due to this wind occur more often in September, followed by August, July and October. When it blows, the temperature can go above 25 ☌ (77 ☏), and sometimes up to 30 ☌ (86 ☏), in the middle of winter, while it can go above 35 ☌ (95 ☏), and sometimes up to 40 ☌ (104 ☏), from from April to October. This wind is more likely to occur in autumn and winter, but it can blow all year round. In addition to the possible waves of bad weather, which occur mainly from December to March, a nuisance in the climate of Los Angeles is represented by the Santa Ana, a hot, dry wind from the northeast, which blows for a few days from the deserts of California and Arizona, after passing over the mountains, from which it descends. The city is quite polluted, and pollutants can accumulate in the air especially in the dry season, from May to October. There are, however, different microclimates depending on area, since the city covers a wide surface, it is situated on the coast, but it's also surrounded by hills and mountains. The city has therefore a really pleasant climate, also because it is kissed by the sun most of the year. In fact, the city is located at a lower latitude than the Mediterranean coasts, so it has milder winters on the other hand, it is located on the Pacific coast, along which a cool current flows (ie the California Current) therefore, summer is a bit cooler than in the Mediterranean Sea. It is similar to the Mediterranean climate but it's even milder. The climate of Los Angeles is subtropical, characterized by very mild, relatively rainy winters and hot, sunny summers.
