In the northern hemisphere, spring is March, April, and May, summer is June, July, and August, autumn is September, October, and November, and winter is December, January, and February. This is divided according to temperature.
Divided according to the months, spring is January, February, and March, summer is April, May, and June, autumn is July, August, and September, and winter is October, November, and December.
Extended information:
In terms of climate, the four seasons are distinguished by temperature. In the northern hemisphere, spring is generally from March to May, summer is from June to August, autumn is from September to November, and winter is from December to February. In the Southern Hemisphere, the seasons are exactly opposite to those in the Northern Hemisphere. When it is summer in the Southern Hemisphere, it is winter in the Northern Hemisphere; when it is winter in the Southern Hemisphere, it is summer in the Northern Hemisphere. There are no clear boundaries between the seasons, and the transition from season to season is gradual.
Change patterns
From the spring equinox through the summer solstice to the autumnal equinox, the northern hemisphere is in the summer half of the year and the southern hemisphere is in the winter half of the year. During this period, the northern hemisphere has long days and short nights, while the southern hemisphere has short days and long nights; the North Pole is in polar day and the Antarctic is in polar night; the height of the sun north of the Tropic of Cancer is always greater than the average, and south of the Tropic of Cancer is less than the average. North of the Tropic of Cancer, the sun rises on the horizon circle in the northeast and sets on the horizon circle in the northwest. On the equinox, the sun rises due east and sets due west all over the world.
From the autumnal equinox through the winter solstice to the spring equinox, the northern hemisphere is in the winter half of the year and the southern hemisphere is in the summer half of the year. During this period, the length of day and night, the length of day and night, the height of day and night, and the height of the sun in the northern and southern hemispheres were all opposite to the above situation. North of the Tropic of Cancer, the sun rises on the horizon in the southeast and sets on the horizon in the southwest.
From the summer solstice through the autumnal equinox to the winter solstice, the northern hemisphere changes from summer to half of the year, and the southern hemisphere changes from winter to summer. During this period, the days in the Northern Hemisphere are getting shorter and the nights are getting longer, and the polar day zone is gradually shrinking; in the Southern Hemisphere, the days are getting longer and the nights are getting shorter, and the polar night zone is gradually shrinking. The height of the sun has been decreasing north of the Tropic of Cancer and increasing south of the Tropic of Cancer. North of the Tropic of Cancer, the rising direction of the sun changes from northeast to southeast, and the setting direction changes from northwest to southwest. The autumnal equinox rises due east and sets due west.
