At the North Pole, the Sun is permanently above the horizon during the summer months and permanently below the horizon during the winter months. Sunrise is just before the vernal equinox (around March 19); the Sun then takes three months to reach its highest point of about 23½° elevation at the summer solstice (around June 21), after which time it begins to sink, reaching sunset just after the autumnal equinox (around September 24).
