Day length is shortening rapidly as winter approaches in the far north. We had 12 hours of daylight at the equinox on September 21st and now there is much less. Day length also shortens more quickly the further north you are. At 78 degrees north, the latitude of our most northerly mooring, the day length will be only 6½ hours by the middle of October and the sun will set for the last time there on October 27, not rising again until February 14. This is polar sunset and polar sunrise. With the onset of winter it is also getting much colder.
