June 21st marks the Summer Solstice in the Northern Hemisphere. On this day, the Earth’s Northern Hemisphere is maximally tilted towards the sun.
– Equator (0° latitude): Experiences roughly 12 hours of daylight and 12 hours of night throughout the year, including on June 21st. Sunlight duration is approximately 12 hours, not more than 12 hours.
– Tropic of Cancer (approx 23.5° N): On June 21st, the sun is directly overhead at noon at the Tropic of Cancer. All locations in the Northern Hemisphere north of the equator experience more than 12 hours of daylight on this day. The closer to the North Pole, the longer the daylight. So, the Tropic of Cancer experiences more than 12 hours.
– Tropic of Capricorn (approx 23.5° S): June 21st is the Winter Solstice in the Southern Hemisphere. Locations south of the equator experience less than 12 hours of daylight on this day (except south of the Antarctic Circle, which has 24 hours of darkness). So, the Tropic of Capricorn experiences less than 12 hours.
– Arctic Circle (approx 66.5° N): On June 21st, all locations north of the Arctic Circle experience 24 hours of daylight (Midnight Sun). 24 hours is definitely more than 12 hours.
Therefore, the Tropic of Cancer and the Arctic Circle experience sunlight of more than 12 hours on June 21st.
On the Northern Hemisphere Summer Solstice (June 21st), all latitudes in the Northern Hemisphere north of the equator experience more than 12 hours of daylight; the duration increases with latitude.
The phenomenon of polar day (24 hours of sunlight) occurs north of the Arctic Circle on June 21st. The duration of daylight increases from 12 hours at the equator to 24 hours at or north of the Arctic Circle on this day.
