Begins September 21, 2024

The Fall season officially begins on Saturday, September 21, 2024, at 3:01 AM EDT. This is the moment when the Sun crosses the celestial equator moving southward. The celestial equator is an imaginary line that circles the Earth halfway between the North and South Poles.

• Autumnal equinox

  The Fall season begins with the autumnal equinox. The word “equinox” comes from the Latin words “aequus” (equal) and “nox” (night). This is because, on the day of the autumnal equinox, the day and night are of equal length all over the world.

• Shorter days

  After the autumnal equinox, the days begin to get shorter and the nights begin to get longer. This is because the Earth is tilted on its axis and the North Pole is starting to point away from the Sun.

• Cooler temperatures

  As the days get shorter, the temperatures also begin to cool down. This is because the Earth is receiving less sunlight.

• Changing leaves

  One of the most noticeable signs of Fall is the changing leaves. As the days get shorter and the temperatures cool down, the leaves on the trees begin to change color. This is because the trees are preparing for winter and they are starting to break down the chlorophyll in their leaves.

The Fall season is a beautiful time of year to enjoy the outdoors and take in the changing scenery. Be sure to make the most of it!

Sun crosses celestial equator

The celestial equator is an imaginary line that circles the Earth halfway between the North and South Poles. The Sun crosses the celestial equator twice a year: once in the spring and once in the fall.

• Vernal equinox

  The Sun crosses the celestial equator moving northward on the day of the vernal equinox, which occurs in March. This is the first day of spring in the Northern Hemisphere and the first day of fall in the Southern Hemisphere.

• Autumnal equinox

  The Sun crosses the celestial equator moving southward on the day of the autumnal equinox, which occurs in September. This is the first day of fall in the Northern Hemisphere and the first day of spring in the Southern Hemisphere.

• Equal day and night

  On the day of the equinox, the day and night are of equal length all over the world. This is because the Sun is directly above the equator and its rays are shining equally on both the Northern and Southern Hemispheres.

• Change of seasons

  The equinoxes mark the change of seasons. The vernal equinox marks the beginning of spring and the autumnal equinox marks the beginning of fall.

The Sun crossing the celestial equator is a significant astronomical event that has been observed by cultures around the world for centuries. It is a reminder of the Earth’s tilt on its axis and the changing seasons that this tilt causes.

Cooler temperatures

As the days get shorter and the Sun’s rays become less direct, the temperatures begin to cool down. This is because the Earth is receiving less sunlight.

• Reduced solar radiation

  The Sun’s rays are less direct in the fall because the Earth is tilted on its axis and the North Pole is starting to point away from the Sun. This means that the Sun’s rays have to travel through more of the Earth’s atmosphere to reach the surface. The atmosphere absorbs some of the Sun’s energy, which reduces the amount of energy that reaches the Earth’s surface.

• Less heat retention

  The Earth’s surface also retains less heat in the fall. This is because the days are shorter and the nights are longer. The Earth’s surface has less time to absorb heat from the Sun during the day, and it has more time to lose heat to the atmosphere at night.

• Changes in wind patterns

  The wind patterns also change in the fall. The prevailing winds in the Northern Hemisphere shift from the west to the east. This means that the wind is coming from colder regions, which further contributes to the cooling temperatures.

• Seasonal lag

  The Earth’s surface takes time to cool down, so the coolest temperatures of the fall season typically occur in November or December, even though the days start getting shorter in September.

The cooler temperatures of the fall season can be a welcome relief from the heat of the summer. However, it is important to be prepared for the changing temperatures and to dress accordingly.

Shorter days

After the autumnal equinox, the days begin to get shorter and the nights begin to get longer. This is because the Earth is tilted on its axis and the North Pole is starting to point away from the Sun.

• Earth’s tilt

  The Earth’s axis is tilted away from the Sun by 23.5 degrees. This tilt is what causes the seasons. As the Earth orbits the Sun, different parts of the Earth are tilted towards or away from the Sun. This results in different amounts of sunlight reaching different parts of the Earth at different times of the year.

• Less direct sunlight

  As the North Pole starts to point away from the Sun in the fall, the Sun’s rays become less direct. This means that the Sun’s rays have to travel through more of the Earth’s atmosphere to reach the surface. The atmosphere absorbs some of the Sun’s energy, which reduces the amount of energy that reaches the Earth’s surface.

• Earlier sunsets

  As the days get shorter, the sunsets also get earlier. This is because the Sun is setting below the horizon at an earlier time each day.

• Later sunrises

  As the days get shorter, the sunrises also get later. This is because the Sun is rising above the horizon at a later time each day.

The shorter days of the fall season can be a reminder to cherish the daylight hours and to make the most of the time spent outdoors.

Changing leaves

One of the most noticeable signs of fall is the changing leaves. As the days get shorter and the temperatures cool down, the leaves on the trees begin to change color. This is because the trees are preparing for winter and they are starting to break down the chlorophyll in their leaves.

Chlorophyll is a green pigment that helps the leaves absorb sunlight and produce food for the tree. As the days get shorter, the trees receive less sunlight and they begin to produce less chlorophyll. This causes the green color of the leaves to fade and other colors to become more visible.

The colors that emerge in the fall leaves are determined by several factors, including the type of tree, the amount of sunlight it receives, and the temperature. Some of the most common fall leaf colors include:

• Yellow: Yellow leaves are caused by the presence of a pigment called carotenoid. Carotenoids are also responsible for the yellow color of carrots, corn, and bananas.
• Orange: Orange leaves are caused by a combination of carotenoids and chlorophyll. As the chlorophyll breaks down, the carotenoids become more visible.
• Red: Red leaves are caused by a pigment called anthocyanin. Anthocyanin is produced in the leaves in response to cold temperatures and bright sunlight.

The changing leaves of fall are a beautiful sight to behold. They are a reminder of the changing seasons and the beauty of nature.

Northern Hemisphere: September – November

In the Northern Hemisphere, the fall season typically lasts from September to November. This is because the Earth’s Northern Hemisphere is tilted away from the Sun during this time of year. This means that the days get shorter and the nights get longer, and the temperatures begin to cool down.

• Autumnal equinox

  The fall season begins with the autumnal equinox, which occurs on September 22 or 23. The autumnal equinox is the day when the Sun crosses the celestial equator moving southward. On the day of the autumnal equinox, the day and night are of equal length all over the world.

• Shorter days

  After the autumnal equinox, the days begin to get shorter and the nights begin to get longer. This is because the Earth’s Northern Hemisphere is tilted away from the Sun, which means that the Sun’s rays are hitting the hemisphere at a more oblique angle. As a result, the days receive less sunlight and the temperatures begin to cool down.

• Cooler temperatures

  As the days get shorter and the Sun’s rays become less direct, the temperatures begin to cool down. This is because the Earth’s surface is receiving less sunlight. The coolest temperatures of the fall season typically occur in November.

• Changing leaves

  One of the most noticeable signs of fall in the Northern Hemisphere is the changing leaves. As the days get shorter and the temperatures cool down, the leaves on the trees begin to change color. This is because the trees are preparing for winter and they are starting to break down the chlorophyll in their leaves.

The fall season in the Northern Hemisphere is a beautiful time of year to enjoy the outdoors and take in the changing scenery. Be sure to make the most of it!

Southern Hemisphere: March – May

In the Southern Hemisphere, the fall season typically lasts from March to May. This is because the Earth’s Southern Hemisphere is tilted away from the Sun during this time of year. This means that the days get shorter and the nights get longer, and the temperatures begin to cool down.

• Autumnal equinox

  The fall season begins with the autumnal equinox, which occurs on March 20 or 21. The autumnal equinox is the day when the Sun crosses the celestial equator moving southward. On the day of the autumnal equinox, the day and night are of equal length all over the world.

• Shorter days

  After the autumnal equinox, the days begin to get shorter and the nights begin to get longer. This is because the Earth’s Southern Hemisphere is tilted away from the Sun, which means that the Sun’s rays are hitting the hemisphere at a more oblique angle. As a result, the days receive less sunlight and the temperatures begin to cool down.

• Cooler temperatures

  As the days get shorter and the Sun’s rays become less direct, the temperatures begin to cool down. This is because the Earth’s surface is receiving less sunlight. The coolest temperatures of the fall season typically occur in May.

• Changing leaves

  In the Southern Hemisphere, the changing leaves of fall are not as noticeable as they are in the Northern Hemisphere. This is because most trees in the Southern Hemisphere are evergreen, which means that they do not lose their leaves in the fall. However, some deciduous trees in the Southern Hemisphere do lose their leaves in the fall, and these trees can put on a spectacular display of color.

The fall season in the Southern Hemisphere is a beautiful time of year to enjoy the outdoors and take in the changing scenery. Be sure to make the most of it!

Autumnal equinox

The autumnal equinox is the day when the Sun crosses the celestial equator moving southward. This occurs on September 22 or 23 in the Northern Hemisphere and on March 20 or 21 in the Southern Hemisphere.

• Equal day and night

  On the day of the autumnal equinox, the day and night are of equal length all over the world. This is because the Sun is directly above the equator and its rays are shining equally on both the Northern and Southern Hemispheres.

• Change of seasons

  The autumnal equinox marks the beginning of fall in the Northern Hemisphere and the beginning of spring in the Southern Hemisphere. This is because the Earth’s tilt on its axis causes the amount of sunlight that reaches different parts of the Earth to vary throughout the year.

• Harvest festivals

  The autumnal equinox has been celebrated by cultures around the world for centuries. Many harvest festivals are held around the time of the autumnal equinox to celebrate the end of the harvest season.

• Astronomical significance

  The autumnal equinox is an important astronomical event. It is one of the two times each year when the Sun is directly above the equator. The other time is the vernal equinox, which occurs in March.

The autumnal equinox is a reminder of the Earth’s tilt on its axis and the changing seasons that this tilt causes. It is a time to celebrate the harvest and to prepare for the coming winter.
