no artificial lighting is needed outdoors. At the winter solstice, the sun rises at 10:01, stays very low above the horizon (at midday its altitude is slightly more than 3 degrees over the horizon), and sets at 14:31. Climate Trondheim city has an oceanic climate (Cfb) or humid continental climate (Dfb), depending on the winter threshold used (−3 °C or 0 °C). The part of the municipality further away from the fjord has slightly colder winters, while the part close to the fjord has the mildest winters. Trondheim is mostly sheltered from the strong south and southwesterly winds which can occur along the outer seaboard but is more exposed to northwesterly winds. As with the rest of Norway, the weather is dependent on the weather pattern. High pressure over Central Norway or to the east gives sunny weather which can last for weeks. Conversely, Atlantic Lows can also dominate for weeks, and both patterns can happen all year. This was demonstrated in 2020 when May saw northwesterlies with cold air from the Greenland Sea lasting three weeks into the month, and snowfall in mid-May, setting a new record for snow in May. The next month, high pressure and weeks with southeasterlies gave the warmest June on record, with 345 sun hours and Trondheim Airport recording a new record high , Norway's warmest high in 2020. Trondheim experiences moderate snowfall from November to March, but mixed with mild weather and rainfall. There are on average 14 days each winter with at least of snow cover on the ground and 22 days with a daily minimum temperature of or less (1971–2000, airport). There is often more snow and later snowmelt in suburban areas at a higher elevation, with good skiing conditions in Bymarka. All the monthly record lows are from 1955 or older, with half of them from before 1920. The last overnight frost in June was in 1958, and the coldest night in May after year 2000 had low −2.7 °C. The May record low is from 1900, 3.7 °C colder than the second coldest May night. The all-time low was recorded February 1899. The all-time high was recorded 22 July 1901. The warmest month on record is July 2014 with mean and average daily high (airport). The coldest month on record is February 1966 with mean and average daily low (airport). The average date for the last overnight freeze (low
