Winter, from December to February, is quite mild: the average January temperature is about 6.5 °C (43.5 °F). However, it can be more or less cold, depending on weather situation: on sunny days, at night the temperature approaches freezing (0 °C or 32 °F), and there may be some morning fog, while the north wind, the "Tramontana", can bring some cold and windy days, and some frosts at night. Every now and then, it can even snow. During intense cold spells, the minimum temperature may drop to -5/-10 °C (5/14 °F).
On the contrary, when the southern currents prevail, the weather becomes milder, but cloudy and with some chance of rain: in these cases, the temperature can reach or exceed 15 °C (59 °F) even in winter.

Spring, from March to May, is mild and gradually more sunny, but it is also quite rainy. March and the first half of April are unstable periods, in which mild and sunny days alternate with rainy and cold days, still quite wintery. From the second half of April, and especially from May, the temperature becomes pleasant in a more constant way, but some rainy periods are still possible.

Summer, from June to August, is hot and sunny. Every now and then, some afternoon thunderstorms may occur, and more rarely also some cool and rainy days, especially in June and in the second half of August. Daytime temperatures, when the weather is nice (and this happens very often), are high, given the distance from the sea and the location in a valley: in fact Florence is often one of the hottest cities in Italy. Every year there are days with maximum temperatures around 36/38 °C (97/100 °F), but sometimes they can get to 40 °C (104 °F). Fortunately, the humidity is not very high, and at night the temperature becomes almost always acceptable.

Autumn, from September to November, is initially warm and pleasant, dry and bright, but it quickly becomes quite rainy, and in fact it is the wettest season, especially in October and November. Sometimes the rains are abundant.

The amount of sunshine in Florence is very good in spring and summer, from May to August, while from November to March the sun is not very frequent, given the frequent passage of weather disturbances, although some sunny days are always possible.

When to go

The best times to visit Florence are from mid-April to mid-June, and the month of September: there will be many nice days, with a pleasantly warm weather, and cool evenings. There will be, however, also some rainy days. Those who can stand the heat can also choose July and August. For safety, it will be useful a sweatshirt for the evening, even in summer.
