Perpetual darkness
When it is winter in the northern hemisphere and summer in the southern hemisphere. The North Pole is tilted away from the Sun in December. (That means that the Northern Hemisphere is also tilted away from the Sun in December.)

Winter
When summer in New Zealand, the Earth's southern regions are tilted towards the Sun, and the North Pole tilted away from it.
When it's winter in the Southern Hemisphere it's summer in the northern hemisphere. Therefore the North geographic pole is tilted towards the sun and the South geographic pole is tilted away from the sun.
When the South Pole is tilted away from the sun, it is winter in the Southern Hemisphere.
Winter. The Earth has an axis, tilted at about 23.5° from the perpendicular to Earth's orbit. When the Earth's north pole is tilted towards the Sun, the northern hemisphere is in summer while the southern hemisphere is in winter. That's the main time when the Sun doesn't set at the north pole. When the Earth's north pole is tilted away from the Sun the southern hemisphere is in summer while the northern hemisphere is in winter.
When the North Pole is tilted toward the Sun, it is summer in the Northern Hemisphere. This tilt allows for longer daylight hours and more direct sunlight, resulting in warmer temperatures. Conversely, the Southern Hemisphere experiences winter during this time, as it is tilted away from the Sun. The opposite occurs when the South Pole is tilted toward the Sun, leading to summer in the Southern Hemisphere.
Seasonally colder weather results from being tilted away from the sun. There is also another kind of cold weather that results from being close to the north pole or the south pole.
the north pole is tilted away from the sun so the suns rays are less direct
At its full extent, the South Pole is tilted about 23.5 degrees toward or away from the Sun.
During the winter solstice, the North Pole is tilted 23.5 degrees away from the sun. This is the reason why the Arctic Circle does not receive any sunlight.
