The summer solstice marks the day with the most number of daytime hours. For people living in the southern hemisphere, the summer solstice occurs on the 21st or 22nd of December. This year, the summer solstice will occur on Tuesday the 22nd of December.



The increase in the number of day time hours occurs due to the axial tilt of the Earth. During the southern hemisphere’s summer, the South Pole points towards the Sun. This results in more of the southern hemisphere being illuminated by the Sun at any given point in time. For people in the northern hemisphere the opposite is true. The North Pole points away from the Sun, resulting in less daylight hours for people in the northern hemisphere
