Climate chart - Palermo (Sicily)
In Palermo, the capital of Sicily, the climate is Mediterranean with very mild, quite rainy winters and hot, sunny summers.
The city is located on the northern coast of Sicily, in an area exposed to the cool mistral wind that blows from Sardinia, but also to the sirocco.
The sirocco, the wind from Africa, is able to raise the temperature by several degrees: it can exceed 20 °C (68 °F) in winter, and can reach or exceed 40 °C (104 °F) in summer.
That of Palermo is one of the most exposed areas because the wind comes from the interior (and not directly from the sea as on the southern Sicilian coast), and in addition, there is an effect of air compression due to the fact that the wind comes down from the mountains. In fact, around Palermo, there are mountains about 1,000 meters (3,300 feet) high, while further south are the Sicani mountains, which reach 1,600 meters (5,200 ft).
The average temperature ranges from 12.2 °C (54 °F) in February to 26.8 °C (80.2 °F) in August. Here are the average temperatures.

Winter, from December to February, is mild, and is characterized by sunny periods alternating with rainy periods.
It rarely gets very cold, although there can sometimes be cold, windy, and rainy days, with highs around 10 °C (50 °F).
Very rarely, and especially in the areas of the city located farther from the coast, it may snow. Snowfalls with accumulation occurred in March 1949, February 1956, January 1962, January 1963, January 1981, January 1999 (when the beach also turned white), and New Year's Eve 2014. However, snow tends to last a few hours and to melt quickly, because the temperature, already almost always above freezing, tends to increase further during the day (it is true that the wind in these cases comes from the north, but the sea is quite warm).
The temperature almost never drops below freezing. The coldest record is -1 °C (30 °F), recorded in January 1962. On other occasions, the temperature reached 0 °C (32 °F) in February 1956, 0.5 °C (33 °F) in January 1981, and 1 °C (34 °F) in January 1999.
Summer, from June to August, is hot and sunny, with very rare rains.
Generally, the temperatures are not too high and the breeze blows, which also brings humidity from the sea.
However, heatwaves of African origin can sometimes occur: in these cases, it is possible for the temperature to reach or exceed 40 °C (104 °F). The record is 45.8 °C (114.4 °F), set in July 2023. On other occasions, the temperature reached 43/44 °C (109/111 °F).
In 2020, the temperature reached 39 °C (102 °F) even in May, and 37.5 °C (99.5 °F) in October. When the sirocco blows at night, the temperature can remain around 30 °C (86 °F), and sometimes not only in summer. For example, on October 14, 1993, the minimum was 31 °C (88 °F).
The amount of sunshine in Palermo is great in summer, when clear skies prevail; in winter, sunny periods alternate with periods of bad weather, with rain, wind and thunderstorms. On average, there are about 2,700 hours of sunshine per year. Here are the average sunshine hours per day.

The sea in Palermo is warm enough for swimming from July to September. In June, the sea is still a little cool, while in October, after the summer, the water temperature is still decent, around 22.5 °C (72.5 °F): in days of fine weather, perhaps with the sirocco, locals go to the beach of Mondello. Here is the average sea temperature.

Best Time
The best time to visit Palermo for a beach holiday is the summer, from June to August. The sea temperature is comfortable enough from July to September, although in September, which in any case is still a good month (especially in the first half), the first periods of bad weather can occur.
To visit the city you can choose spring, in April and May, and the beginning of autumn, from mid-September to mid-October.
