Grimsey, where it's located

The climate of Grimsey is subarctic, with cold winters and very cool summers, or even a little cold.
Grimsey is a small island located north of Iceland, and is the only point in the country to be crossed by the Arctic Circle. However, thanks to the atmospheric refraction, the sun can be seen for a while even at the winter solstice, in fact, on December 21st, the sun rises at noon and sets at 2:15 pm. Instead, on the longest days, from June 7th to July 6th, the sun does not set, but remains just above the horizon around midnight. Besides, the white nights, in which the sun sets but it does not become completely dark, occur from May 10th and then until August 3rd, and less clearly already from April 21st and until August 23rd.
