Growing up as a curious kid, I always wondered what magic makes summer days longer and nights seem short. Like most kids, I asked my friend’s older brother why? He said that time is only about perspective. But as I grew up, I realized something more exciting. When it’s winter in North America, then it is summer in some other continents, like South America and Australia. So I found out the reason and cracked it. Do you want to learn something exciting? Let’s dig.
Why are days longer than nights during the summer season? Although all days have 24 hours, including summer days, summer days are longer because of the tilt in the earth’s axis as it rotates and revolves around the sun. The Earth is tilted at an angle, and so if your continent is on the upper tilted side up to the sun, the sun’s rays get to brighten your side for longer since the sun scatters its rays.
Many people think that the temperature changes because the Earth is farther from the sun in winter and closer in summer. But that’s wrong. Scientific research has shown that the Earth goes farther away from the sun in July and is closest to the sun in January! What makes us see the difference in the days, and how is it created?
The Reason For The Seasons
The four seasons that you see each year come about as a result of the 23.4-degree tilt in the Earth’s axis. Imagine a world like ours that revolves around its star as the Earth revolves around the sun. If it is rotating as a giant meatball hung on a puppet string, that world would be a planet that has weather but will not have any seasons or variation in the length of days, and there will be no polar nights, no midnight Suns. Bah, it will be a world much less beautiful, much less dramatic than our Earth.
So why are days longer and warmer in Summer? Now imagine holding a round soccer ball that is a little bit compressed. Imagine a straight line drawn around the middle. That is the same as the Earth. That line around our earth is the equator, and the equator divides the globe into two parts. Both parts are called hemispheres. Hence, we have the Northern Hemisphere and the Southern Hemisphere. If you are in the Northern Hemisphere and you have summer, guys in the Southern Hemisphere will be in the winter season. Now, in Summer the days are longer, while in winter days are shorter.
If you are reading a map, you look at flat earth, and you see the north pole and the south pole up and down, right? In reality, the earth is like a ball, and it is tilted at 23.4 degrees out of 360 degrees of a complete circle. It is because of this tilt that summer days get long and winter days short. The simple explanation, though is that in revolution, the earth can move the northern hemisphere close to the sun and that is summer. Now, the hemisphere that’s tilted closest to the Sun would have the longest, brightest days and that is because that hemisphere would be hit directly by the Sun’s rays. The other hemisphere that is opposite would get short days.
What Days Are Shorter, Is The Sun Moving?
Why? The Earth never stays in one place like a soccer ball. The earth is not a perfect round, and it is an oval shape. The earth goes around the sun in orbit. This complete orbit makes one year. For those of us who live in the Northern Hemisphere, December days are short and cold. The Sun seems early to bed and late to rise that’s not because the Sun is moving, it’s because our Earth is moving. When we’re in winter, it’s not that our part of the planet is further from the Sun, it is because the sun’s rays fall on us less directly. While our days are at their darkest, our friends in the southern hemisphere are down there enjoying their sunniest and warmest season. Around December 21st, the days are as long and bright in the southern hemisphere as they ever get and just as short and dark in the northern hemisphere. The solstices, you have probably heard of that, are the moments when winter and summer reach their climax and begin to fall back towards each other. So, by about June 21st, they’ve changed places. For those who are near the equator, they may not notice any change at all but only as they get closer to the poles, the difference in length of days get and more extreme all over the planet.

Does The Earth Move Faster In Summer?
Like athletes that run circular tracks, the runners that are closer to the roundabout gets by faster than those who are farther away. Same goes with the earth’s revolution around the sun. The Earth moves faster when it is closer to the sun, and the other hemisphere that is farther comes around later. Put, when our planet is closer to the sun, it moves faster around its orbit, and when it is further away, it moves so much slower. However, because of the tilt, the hemisphere closer to the sun gets around first. So when the northern hemisphere has winter, the earth is moving faster and this makes the season and the days shorter. At the equator, the surface of the planet moves at a speed of 460 meters per seconds (approximately 1,000 miles per hour). The earth covers its revolution around the sun route at a rate of nearly 30 kilometers per sec or 67,000 miles per hour.
What Happens After The Longer Day?
The summer solstice is always the longest ever seen day of the year. The summer solstice begins immediately when the tilt of the Earth’s axis is most inclined towards the sun. In the summer solstice, the sun shines for as long as 17 hours. That’s the longest day of the year ever for those who have summer in their hemisphere. After the longest day of the year, which is the solstice, the summer begins. And you can have days of fun ahead.
The seasons, the change in days and the length of sunshine in the days are all caused by the 23.4-degree angle tilt of the earth. So next time someone asks you, you know what to do, Einstein! You should read more to see more answers to your pestering questions.
