The sun and the clock in Tromsø (2026)
Tromsø lies at 19.0°E. Its time zone, UTC+1, is built around the 15°E meridian. The 4.0° gap between them means the clock runs roughly 16 minutes behind the sun: solar noon arrives at about 11:44 rather than 12:00. Under daylight saving the clocks move 60 minutes forward, widening the gap to 44 minutes and pushing solar noon to 12:44.
Tromsø is inside the polar circle. Across 2026 the sun never sets on 69 days around midsummer, and never rises on 48 days around midwinter. Beyond the polar circle the sun stops rising and setting daily for part of the year.
The sky stays usably light for a while after the sun goes down. In Tromsø that civil twilight runs about 60 minutes at the equinox.
Every figure in this section is computed from the city's own latitude, longitude and IANA time zone using NOAA solar algorithms (Spencer, 1971), accurate to about ±2 arcminutes below 65° latitude.
