Endless summer

At this time of year in Svalbard, Norway, the Sun crests the horizon and won’t dip below it again for more than five months. From about 19 April to 23 August, it’s nothing but sunshine on this island above the Arctic Circle, more than 500 miles north of mainland Norway. But it’s far from a day at the beach, with average summertime highs of 4C to 7C (toasty compared to average wintertime temps of -15C to -13C).
