In the Northern Hemisphere, summer is the warmest season, occurring between spring and fall. Its start and end dates vary depending on the astronomical definition used and location on Earth. Astronomically, summer begins with the summer solstice, the day with the longest period of daylight and shortest night of the year, and ends with the autumnal equinox, when day and night are of equal length.
Meteorologists, however, define summer as the warmest three months of the year, May through July in the Northern Hemisphere. This definition is based on the fact that the Earth’s surface heats up and cools down more slowly than the atmosphere, so the warmest part of the year lags behind the astronomical summer.
## When Does Summer End In 2025
Summer ends on different dates depending on the definition used. Astronomically, summer ends with the autumnal equinox, which occurs on September 22 or 23 in the Northern Hemisphere in 2025. Meteorologically, summer ends on August 31 in the Northern Hemisphere in 2025.
- Astronomical summer: June 21 – September 22/23
- Meteorological summer: June 1 – August 31
- Summer solstice: June 21
- Autumnal equinox: September 22/23
- Northern Hemisphere
- 2025

So, to answer the question “When does summer end in 2025?”, it depends on the definition used. Astronomically, summer ends on September 22 or 23, 2025. Meteorologically, summer ends on August 31, 2025.
Astronomical summer: June 21 – September 22/23
Astronomical summer is the period of time between the summer solstice and the autumnal equinox. The summer solstice is the day with the longest period of daylight and shortest night of the year, and the autumnal equinox is the day when day and night are of equal length.
-
Summer solstice:
The summer solstice occurs on June 21 or 22 in the Northern Hemisphere. On this day, the Sun reaches its highest point in the sky and the day is at its longest. The amount of daylight varies depending on latitude, with the longest days occurring at the poles and the shortest days occurring at the equator.
-
Summer:
The period of time between the summer solstice and the autumnal equinox is known as summer. During this time, the days are long and the nights are short. The Sun is high in the sky during the day, and the weather is typically warm and sunny.
-
Autumnal equinox:
The autumnal equinox occurs on September 22 or 23 in the Northern Hemisphere. On this day, the Sun crosses the celestial equator moving southward. Day and night are of equal length all over the world on the autumnal equinox.
-
End of summer:
Astronomical summer ends on the autumnal equinox. After this day, the days start to get shorter and the nights start to get longer. The Sun is lower in the sky during the day, and the weather starts to cool down.
In 2025, the summer solstice will occur on June 21 and the autumnal equinox will occur on September 23. Therefore, astronomical summer will last from June 21 to September 23 in 2025.
Meteorological summer: June 1 – August 31
Meteorological summer is the warmest three months of the year, as defined by meteorologists. In the Northern Hemisphere, meteorological summer runs from June 1 to August 31.
-
Based on temperature:

-
June 1 – August 31:
In the Northern Hemisphere, meteorological summer runs from June 1 to August 31. These months are typically the warmest of the year, with average temperatures above 20 degrees Celsius (68 degrees Fahrenheit).
-
Varies by location:
The exact dates of meteorological summer can vary depending on location. In some areas, summer may start earlier or end later than June 1 to August 31.
-
Useful for forecasting:
Meteorological summer is a useful concept for meteorologists, as it allows them to track and predict weather patterns during the warmest months of the year.
In 2025, meteorological summer will run from June 1 to August 31. These months are likely to be the warmest of the year in the Northern Hemisphere, with average temperatures above 20 degrees Celsius (68 degrees Fahrenheit).
Summer solstice: June 21

-
Equal day and night:
The autumnal equinox is the only day of the year when day and night are of equal length all over the world. This is because the Sun is directly above the equator on this day.
-
Changing seasons:
The autumnal equinox marks the beginning of astronomical autumn, which is the period of time between the autumnal equinox and the winter solstice. The autumnal equinox is also a time when the days start to get shorter and the nights start to get longer in the Northern Hemisphere.
-
Harvest time:
In many cultures, the autumnal equinox is associated with harvest time. This is because the autumnal equinox occurs around the time when many crops are ready to be harvested.

Northern Hemisphere
The Northern Hemisphere is the half of Earth that is north of the equator. It includes North America, Europe, Asia, and parts of Africa and South America.
The Northern Hemisphere experiences four seasons: spring, summer, autumn, and winter. Summer in the Northern Hemisphere begins with the summer solstice, which occurs on June 21 or 22, and ends with the autumnal equinox, which occurs on September 22 or 23. During summer in the Northern Hemisphere, the days are long and the nights are short. The Sun is high in the sky during the day, and the weather is typically warm and sunny.
The Northern Hemisphere is home to a variety of climates, from tropical to polar. The climate of a particular region in the Northern Hemisphere depends on its latitude, altitude, and distance from the ocean. For example, the tropics are located near the equator and have a warm climate all year round. The polar regions are located near the North Pole and have a cold climate all year round. The temperate regions are located between the tropics and the polar regions and have a climate that varies with the seasons.
The Northern Hemisphere is a vast and diverse region, with a wide range of climates and ecosystems. It is home to a variety of cultures and languages. The Northern Hemisphere is also the most populous hemisphere on Earth, with over 6 billion people living in the region.
The Northern Hemisphere is a fascinating and complex region. It is a place of great beauty and diversity, and it is home to a majority of the world’s population. The Northern Hemisphere is also a region that is facing a number of challenges, including climate change and pollution. It is important to understand the Northern Hemisphere and the challenges it faces in order to find solutions to these problems.
