Climate in Ancona (Marche)

The climate of Ancona can be described as transitional Mediterranean. In fact, the city is located north enough to partially undergo some influences typical of northern Italy (such as the fog in winter and early spring), as well as the typical influences of the Adriatic side (such as cold air intrusions from Russia).
The city is located in north-central Italy, on the Adriatic coast, and is the capital of the Marche region.
The position on a promontory, surrounded by the sea on two sides, makes the climate quite windy.
The meteorological station is located at the Falconara Marittima airport, and therefore has slightly more continental values, typical of the plain. Here, the average temperature of the coldest month (January) is of 5.8 °C (42.4 °F), that of the warmest months (July and August) is of 23.9 °C (75 °F). Here are the average temperatures.

Precipitation amounts to 740 millimeters (29 inches) per year: so, it is at an intermediate level. It ranges from 45 mm (1.8 in) in the driest months (January, July) to 85 mm (3.3 in) in the wettest (November). Here is the average precipitation.

The winter, from December to February, is quite cold.
There are quite mild periods, in which Atlantic currents prevail, during which there can also be rainy days. When the warm wind from the south-west (Garbino) blows, which comes down from the Apennines, the temperature can reach and exceed 20 °C (68 °F) even in the middle of winter.
In periods of good weather, fog can form.
On the other hand, the wind from Eastern Europe, sometimes even in March, can bring about cold periods, in which snow can also fall. During the coldest winters, snowfalls can be abundant, and can reach or exceed half a meter (20 inches), as happened in February 1929, February 1956, January 1985 and February 2012.
Given the location on the coast, frosts are generally not intense, and on the coldest nights of the year, the temperature does not go below -4/-5 °C (23/25 °F). However, during the most intense cold spells, it dipped lower.
The temperature reached -13 °C (8.5 °F) in February 1963, -10.5 °C (13 °F) in January 1966, -15.5 °C (4 °F) in January 1967, -12.5 °C (9.5 °F) in January 1968, -12 °C (10.5 °F) in March 1971, -11 °C (12 °F) in January 1979, -13 °C (8.5 °F) in January 1985, -12.5 °C (9.5 °F) in February 1991, -10 °C (14 °F) in December 1996, and -8.5 °C (16.5 °F) in February 2012. Such low values, although rare, make us understand that the city is more prone to the cold than central and southern Italy.

The summer, from June to August, is hot and sunny, with rare rainy days and a few thunderstorms coming from the Apennines. Generally, it is less hot than in Florence, and the breeze blows from the sea in the afternoon, however, there can be hot and sultry periods, moreover, sometimes the Garbino can bring some torrid days.
The heat record, 41 °C (106 °F), was recorded in July 1968. Since then, the temperature reached 40.5 °C (105 °F) in July 1983, 39 °C (102 °F) in July 2000, 39.5 °C (103 °F) in August 2003, and 40 °C (104 °F) in August 2017.



On average, there are around 2,220 sunshine hours per year, therefore less than in the real Mediterranean climate. Here are the average sunshine hours per day.

The sea temperature ranges between 12 °C (54 °F) and 25 °C (77 °F). The sea is warm enough for swimming from July to September. Here are the average sea temperatures.
