Don"t lose your sunglasses! At least not during this time of year in Svalbard, Norway, when the sun crests the horizon and never dips below it again for more than four months. From about April 19 to August 23, it"s nothing but sunshine in this island chain above the Arctic Circle, more than 500 miles north of mainland Norway. It"s not quite a day at the beach, with average summertime high temps of 39 to 45 degrees Fahrenheit (toasty compared to average wintertime temps of 5 to 9 degrees). And who knows how far it is to the nearest Ray-Ban store?
