Because that is how "beginning of summer" is defined.
Trying to look into the reasoning why you might have asked the question... you might have been thinking that summer should be equally spaced on both sides of the northernmost point reached by the sun, instead of all occurring after the sun has reached its northernmost point.
However, that point occurs in late June, and if you'll think about it a bit, you'll probably realize that the hottest days you can remember happened in late July or August rather than in early June or late May. It takes the Earth a while to warm up (or cool down), so the temperature lags a bit behind the position of the sun. This is why we start the count on the solstice, rather than spacing it to either side of the solstice.
northern hemisphere people
In the southern hemisphere it is winter when in the northern hemisphere it is summer.
South America is located in three hemispheres. They are the Northern, Western and Southern Hemispheres. As of 2011, South America has a population of 387.5 million people.
To simulate snow on the trees, which they would have outdoors in winter.Because Argentina is in the Southern Hemisphere, which has opposite seasons from the Northern Hemisphere, Christmas there is in the summer. (Their summer solstice is December 21 or 22.)
India is in the Northern Hemisphere. Australia is in the Southern hemisphere. The Earth's axis has a 23.5 degree tilt. So on December 21st, the Southern Hemisphere is closest to the Sun, while the Northern Hemisphere is closest to the Sun on June 22nd.
northern hemisphere people
People live in both the Northern and Southern Hemisphere.
There are more people living in the northern hemisphere compared to the southern hemisphere. This is because the majority of the world's population is concentrated in countries located in the northern half of the globe.
Western and Northern hemisphere
USA people primarily live in the Northern Hemisphere.
In the southern hemisphere it is winter when in the northern hemisphere it is summer.
No. One of the better known constellations in the northern hemisphere is the big dipper. People in the southern hemisphere can't see this. In the south the well known constellation is the southern cross, and you can't see this in the northern hemisphere.
More people live in the northern hemisphere than in the southern hemisphere. This is because the majority of Earth's landmass is in the northern hemisphere, which includes populous countries like China, India, the United States, and Russia.
Because it is winter in the Southern Hemisphere.
Greenland is the least populated country in the northern hemisphere, with a population of around 56,000 people.
