With the arrival of warmer weather and longer days, it's natural to wonder when spring begins. The answer depends on whether you're referring to the astronomical or the meteorological definition of the season.
The astronomical definition of spring is based on the Earth's position in its orbit around the sun. Spring officially begins on the spring equinox, which occurs on March 20 or 21 each year. This is the day when the sun crosses the celestial equator moving northward, and day and night are of equal length all over the world.
The meteorological definition of spring is based on temperature patterns and typically begins on March 1 and ends on May 31 in the Northern Hemisphere. This definition is used by meteorologists and climatologists to track and predict weather patterns and is more relevant for everyday weather discussions.
In Which Month is Spring?
Spring, a season of renewal and growth, arrives at different times depending on the definition used.
- Astronomical Spring:
- March 20 or 21
- Spring Equinox
- Equal Day and Night
- Meteorological Spring:
- March 1 to May 31
- Weather Patterns
- Climate Tracking
The astronomical definition marks the start of spring based on the Earth's position, while the meteorological definition is based on temperature patterns.
Astronomical Spring:
Astronomical spring is based on the Earth's position in its orbit around the sun, rather than on temperature patterns.
- Spring Equinox:
The astronomical start of spring is marked by the spring or vernal, which occurs on March 20 or 21 each year.
- Equal Day and Night:
On the spring, the sun crosses the celestial equator moving northward, resulting in equal hours of daylight and darkness all over the world.
- Earth's Tilt:
The Earth's tilt on its axis causes the amount of daylight to increase in the Northern Hemisphere and decrease in the Southern Hemisphere during spring.
- Seasonal Change:
The spring represents the transition from winter to summer, with increasing temperatures and the return of plant growth and animal activity.
Astronomical spring is a key moment in the Earth's annual cycle, marking the official start of the season of renewal and growth.
March 20 or 21
The exact date of the spring equinox, which marks the astronomical start of spring, varies slightly each year due to the Earth's orbit around the sun. However, it typically occurs on March 20 or 21 in the Northern Hemisphere and September 22 or 23 in the Southern Hemisphere.
On the spring equinox, the sun crosses the celestial equator moving northward, resulting in equal hours of daylight and darkness all over the world. This is a significant moment in the Earth's annual cycle, as it represents the transition from winter to spring.
After the spring equinox, the days in the Northern Hemisphere start to get longer and the nights shorter. This is because the Earth's tilt on its axis causes the Northern Hemisphere to tilt towards the sun during this time of year, resulting in more direct sunlight and warmer temperatures.
The arrival of spring is often celebrated with festivals and traditions around the world. In many cultures, spring is seen as a time of renewal and rebirth, and people participate in activities such as planting seeds, cleaning their homes, and gathering with friends and family to celebrate the new season.

Spring Equinox
The spring equinox is a significant astronomical event that marks the official start of spring. It occurs when the sun crosses the celestial equator moving northward, resulting in equal hours of daylight and darkness all over the world.
The date of the spring equinox varies slightly each year due to the Earth's orbit around the sun, but it typically occurs on March 20 or 21 in the Northern Hemisphere and September 22 or 23 in the Southern Hemisphere.
The spring equinox is a reminder of the Earth's tilt on its axis and its annual orbit around the sun. As the Earth orbits the sun, different parts of the planet receive more or less direct sunlight at different times of the year. During the spring equinox, the Northern Hemisphere is tilted towards the sun, resulting in more direct sunlight and warmer temperatures.
The spring equinox is often celebrated with festivals and traditions around the world. In many cultures, spring is seen as a time of renewal and rebirth. People may participate in activities such as planting seeds, cleaning their homes, and gathering with friends and family to celebrate the new season.
The spring equinox is a key moment in the Earth's annual cycle, marking the transition from winter to spring and the arrival of longer days and warmer weather.
Equal Day and Night
One of the most fascinating aspects of the spring equinox is the occurrence of equal day and night all over the world.
- Duration of Daylight and Darkness:
On the spring equinox, the Earth's axis is tilted neither towards nor away from the sun. This means that the sun's rays strike the Earth's equator directly, resulting in 12 hours of daylight and 12 hours of darkness at all latitudes.
- Global Phenomenon:
The spring equinox is the only day of the year when this phenomenon occurs globally. At all latitudes, from the Arctic Circle to the Antarctic Circle, people experience equal hours of daylight and darkness.
- Seasonal Transition:
The equal day and night of the spring equinox mark the transition from winter to spring. After this day, the days in the Northern Hemisphere start to get longer and the nights shorter, while the opposite occurs in the Southern Hemisphere.
- Cultural Significance:
In many cultures, the spring equinox is seen as a time of balance and harmony. It is often associated with festivals and traditions that celebrate the arrival of spring and the return of longer days.
The equal day and night of the spring equinox is a reminder of the Earth's tilt on its axis and its annual orbit around the sun. It is a moment of perfect balance and a symbol of the changing seasons.
Meteorological Spring:
Meteorological spring is a three-month period, typically defined as March 1 to May 31 in the Northern Hemisphere and September 1 to November 30 in the Southern Hemisphere. This definition is used by meteorologists and climatologists to track and predict weather patterns, and it is more closely aligned with the seasonal changes in temperature and precipitation that people experience.
The start of meteorological spring is based on the average temperature trends over many years. Meteorologists have found that, on average, temperatures begin to rise consistently in early March in the Northern Hemisphere and early September in the Southern Hemisphere. This marks the transition from the colder temperatures of winter to the warmer temperatures of spring.
Meteorological spring is also characterized by changes in precipitation patterns. In many regions, spring is a time of increased rainfall or snowfall, as the warmer temperatures cause more evaporation and the jet stream moves northward. This can lead to heavy rains, thunderstorms, and even severe weather outbreaks in some areas.
While meteorological spring is based on temperature and precipitation patterns, it does not always align perfectly with the astronomical definition of spring. In some years, the weather may still be cold and winter-like in early March, or it may be unusually warm in February. However, over the long term, meteorological spring provides a consistent way to track and predict seasonal changes in weather patterns.
Meteorological spring is an important tool for meteorologists and climatologists, helping them to understand and forecast weather patterns and to provide valuable information to the public.
March 1 to May 31
Meteorological spring, which is based on temperature and precipitation patterns, typically begins on March 1 and ends on May 31 in the Northern Hemisphere. This three-month period is characterized by a transition from the colder temperatures of winter to the warmer temperatures of summer.
Changing Temperatures:
During meteorological spring, temperatures gradually rise as the days get longer and the sun's rays become stronger. On average, temperatures increase by about 10 degrees Fahrenheit (5.6 degrees Celsius) from March to May in the Northern Hemisphere. This warming trend is caused by the increasing amount of solar radiation reaching the Earth's surface.
Precipitation Patterns:
Meteorological spring is also a time of changing precipitation patterns. In many regions, spring is a time of increased rainfall or snowfall. This is because the warmer temperatures cause more evaporation, leading to the formation of clouds and precipitation. Additionally, the jet stream, a band of strong winds in the upper atmosphere, moves northward during spring, bringing storms and precipitation to different parts of the world.
Flora and Fauna:
The arrival of meteorological spring brings about noticeable changes in the natural world. Plants begin to bloom, trees start to bud, and animals emerge from hibernation. This renewed activity is a sign of the Earth's transition from winter dormancy to the vibrancy of spring.
Meteorological spring is a time of change and renewal, as the Earth awakens from the cold of winter and prepares for the warmth of summer.
Weather Patterns
Meteorological spring is characterized by a variety of weather patterns, as the Earth transitions from the cold and stable conditions of winter to the warmer and more variable conditions of summer.
Temperature Fluctuations:
Spring is often a time of fluctuating temperatures. Warm days may be followed by cool nights, and sudden changes in temperature are common. This is because the Earth's surface is warming rapidly during the day due to the increasing solar radiation, but the nights are still relatively cool due to the lack of sunlight. Additionally, the jet stream, a band of strong winds in the upper atmosphere, is more active in the spring, bringingの変化する気温 various weather systems across different regions.
Storms and Severe Weather:
Spring is also a time of increased storm activity in many parts of the world. Thunderstorms, hailstorms, and tornadoes are more common during this season. This is because the warmer temperatures and increased moisture in the atmosphere create favorable conditions for the development of severe weather. Additionally, the jet stream can act as a pathway for storms to travel across large distances, leading to widespread severe weather outbreaks.
Seasonal Allergies:
For many people, spring also brings the onset of seasonal allergies. As plants begin to bloom and release pollen into the air, people with allergies may experience symptoms such as sneezing, a runny nose, and itchy eyes. The severity of allergy symptoms can vary depending on the type of pollen and the individual's sensitivity.
The weather patterns of spring can be unpredictable and varied, but they are also a reminder of the Earth's changing seasons and the beauty of the natural world.
Climate Tracking
Meteorological spring is an important period for climate tracking and monitoring, as it marks the transition from the cold season to the warm season.
- Temperature Monitoring:
Meteorologists and climatologists monitor temperature trends during spring to track the rate at which the Earth's surface is warming. Rising temperatures in the spring can be an indicator of long-term climate change and global warming.
- Precipitation Patterns:
Spring is a time of changing precipitation patterns, with some regions experiencing increased rainfall or snowfall and others experiencing drought conditions. Monitoring these patterns helps scientists understand how climate change is affecting regional weather patterns.
- Seasonal Shifts:
Climate tracking also involves monitoring the timing of spring events, such as the arrival of migratory birds, the blooming of flowers, and the melting of snow and ice. Shifts in these seasonal events can provide insights into the impacts of climate change on ecosystems and biodiversity.
- Extreme Weather Events:
Spring is a time of increased storm activity and severe weather outbreaks. Tracking these events and their impacts helps scientists understand how climate change is influencing the frequency and intensity of extreme weather.
Climate tracking during meteorological spring provides valuable data for scientists and policymakers to monitor and understand the impacts of climate change and to develop strategies for adaptation and mitigation.
