Editing Harstad Municipality (section)

===Climate and light===
Despite being located north of the [[Arctic Circle]], Harstad features either a dry-summer [[subarctic climate]] ([[Köppen climate classification]]: '''Dsc'''), or (barely, by only half a degree C)<ref>{{Cite web |title=MSN |url=https://www.msn.com/en-us/ |access-date=2023-10-26 |website=www.msn.com}}</ref> the rare [[cold-summer mediterranean climate]] ([[Köppen climate classification]]: '''Csc'''), depending on if the {{convert|0|C}} or the {{convert|-3|C}} isotherm is used. Harstad features relatively mild, wet winters and cool, dry summers. Harstad does not have the brutal winters most locations north of the Arctic Circle experience, and is sheltered from Atlantic gales by mountains in the west, and has the main part of the [[Scandinavian Mountains]] to the east. The city experiences warmer winters than major cities located 25 degrees farther south in latitude such as [[Beijing]], [[Chicago]] and [[Toronto]]. Summers in Harstad are cool, with average high temperatures seldom breaking the {{convert|22|C|F|0}} mark. Since the weather station opened August 2002, July 2014 was the warmest month with mean {{convert|16.9|C|F|0}}, average daily high {{convert|21.8|C|F|0}} and all-time high  {{convert|31.7|C|F|0}} on 10 July. The record low of {{convert|-16.1|C|F|0}} was recorded in February 2010. The coldest month recorded was January 2003 with mean {{convert|-6.5|C|F|0}} and average daily low {{convert|-9.5|C|F|0}}. On 9. September 2024 Harstad recorded high {{convert|25.9|C|F|0}}, the warmest temperature in September recorded in Troms.

The municipality enjoys the [[midnight sun]] during the summer months, from 22 May to 18 July. There is also a period from early May to early August with twilight for a few hours each night as the sun just dips below the horizon, so there is no darkness. The [[polar night]], when the sun is always below the horizon, lasts from 30 November to 12 January. At this time, there are 3–4 hours of dawn and dusk around noon, sometimes with colourful skies towards the south. From late January, the period of daylight rapidly increases, reaching 12 hours by March and 18 hours in April. Harstad is located in the midst of the [[aurora borealis]] ({{aka}} ''the northern lights'') zone, and the aurora can often be seen on clear nights, but not in summer due to the continuous daylight.
