Solstices are a peculiar cosmic event that stirs curiosity among many. The summer solstice, which marks the longest day of the year in the Northern Hemisphere and the start of summer, might seem straightforward, but there are some enlightening facts that illuminate the true nature of this astronomical phenomenon. Here's everything you need to know, unfiltered.
Misconceptions debunked
- Day length myth: The popular notion that day length is consistent across all latitudes on the Northern Hemisphere during the summer solstice is false. For instance, individuals in Munich experience a day that's 16 hours and 7 minutes long, while folks in Kiel witness the sun for 17 hours and 17 minutes. Only at the equator do days and nights maintain a constant 12-hour duration.
- Solstice synchronization: It's accurate to state that the summer solstice on the Northern Hemisphere coincides with the winter solstice on the Southern Hemisphere. As days grow longest in the Northern Hemisphere, nights become longest in the Southern Hemisphere. This year, the summer solstice on June 21 will denote the summit of the sun's annual path at 04:42 CEST[1].
- Fixed date: Contrary to belief, the summer of 2024 will begin on June 20 due to the inconsistency in the Gregorian calendar and Earth's precise orbit around the sun[2]. This misconception arises because people assume the calendar and astronomical event are interchangeable.
- Sunset during solstice: The sun does set in most regions of the Northern Hemisphere, although later in the evening on the summer solstice. However, north of the Arctic Circle, there exists the phenomenon known as the Midnight Sun, where the sun doesn't set for weeks around the summer solstice. On the other hand, these regions experience several weeks of polar night in winter, plunging them into darkness even during the day[1].
Sun, Earth, and Seasons
Interestingly, while it might seem that the Earth is closer to the Sun in the summer, the opposite is true. The Earth's elliptical orbit results in it being further from the Sun during summer in the Northern Hemisphere than in winter[1]. The angle at which sunlight strikes Earth is what ultimately determines the warming effect, with steeply angled sunlight causing the greatest heat absorption[3].
In summary, the summer solstice is far from being a simple event, with intricate relationships between the Earth, sun, and our calendar contributing to its unique occurrence. Stay informed and continue to explore the fascinating world of astronomy!

In the realm of astronomy, the Earth's elliptical orbit around the sun plays a significant role in determining the disparate day lengths during the summer solstice, even though the Earth is actually further from the sun during this period. This fascinating interplay between the Earth, sun, and our calendar leads to the unique occurrence of the summer solstice, shedding light on the complexities of climate-change and environmental-science, while demonstrating the importance of understanding our planetary position to predict weather patterns.
