The climate of Udine is moderately continental, with cold, damp winters and hot, muggy summers.
The city is located in north-eastern Italy, in the Friuli-Venezia Giulia region, in the Venetian plain, which has a slightly milder climate than the Po valley (see Milan, Turin), but also a little more windy, given that it is exposed to both the bora (cold and dry north-east wind) and the sirocco (mild south-east wind).
Snowfalls are rare, because in cold weather, the bora wind blows, cold and dry, while in bad weather, the sirocco blows from the sea and raises the temperature.
The average temperature of the coldest month (January) is of 3,7 °C (39 °F), that of the warmest month (June) is of 25,6 °C (78 °F). Here are the average temperatures.

Precipitation amounts to 1,210 millimeters (47,6 inches) per year: it is therefore quite abundant. It ranges from 60 mm (2,4 in) in the driest month (February) to 140 mm (5,5 in) in the wettest (June). Here is the average precipitation.

Best Time

The best period to visit Udine is that of spring and early summer, and in particular, from mid-April to mid-June. September, too, is a good month. However, you have to take into account some rainy days in both periods.
Summer can be hot, although some days can be acceptable, especially in June. In summer, and sometimes in May, sudden thunderstorms in the afternoon or evening must be put into account.
