However the climate varies considerably from coastal to inland areas. The coastal regions have a climate with relatively mild winters (7 to -4 degrees centigrade) and cool summers (12 to 20 degrees centigrade). Inland areas have a continental climate with cold winters (-10 to -15 degrees centigrade) and warm summers (15 to 25 degrees centigrade).
Stavanger is situated by the coast and has a climate with relatively mild winters (7 to –4 degrees centigrade) and cool summers (12 to 20 degrees centigrade).
An interesting phenomenon in Norway is the seasonal change in the length of day and night. In midwinter, daylight lasts less than six hours in the southern part of the country, while in the far north darkness prevails. In midsummer, daylight takes over and there is no "real" night during June and July, even as far south as Trondheim (this cannot be observed in Stavanger, though).
