Sunshine and UV index
Sunshine duration is about 2,500-2,700 hours per year, from 147 – average 4.7 hours of sunshine per day in December to 338 – average 10.9 hours of sunshine per day in July.[8] This is the upper-average value for the southern half of Europe because in this part of the continent, sunshine duration varies from about 2,000 to about 3,000 hours per year. However, this is 60% larger value than in northern half of Europe, where sunshine duration is around 1500 hours per year. In winter Rome has about three times more sun duration than in the northern half of Europe. With the exception of Madrid,[9] Lisbon[10] and Athens,[11] Rome has the highest UV index between European capitals (only in the continent) and values close to that of Chicago at 41.9 °N as ultraviolet radiation is less interfered with by other geographic variables, but with a moderate annual average with index equal to 5, which allows direct exposure to the sun at some times of the year. Values range from 1 (December) to 9 (July).[12]
