<P> Around the summer solstice ( approximately 21 June in the Northern Hemisphere and 22 December in the Southern Hemisphere ) , the sun is visible for the full 24 hours , given fair weather . The number of days per year with potential midnight sun increases the closer towards either pole one goes . Although approximately defined by the polar circles , in practice the midnight sun can be seen as much as 55 miles ( 90 km ) outside the polar circle , as described below , and the exact latitudes of the farthest reaches of midnight sun depend on topography and vary slightly year - to - year . </P>
