Now is the time that we should talk about the meteorological definition of the spring equinox. ![]() Spring Equinox – First Day of Spring or Mid-spring? In fact, this process of longer days and shorter nights will go on until the arrival of the December solstice. Therefore, in the southern hemisphere, the days will become longer and longer with each passing day. In other words, after September Equinox, the sun will start to move southward. Second, You can notice that the days are getting longer and the nights are getting shorter. First, you will feel that the weather starts to turn warmer, trees begin to grow their leaves, plants start to flower, etc. ![]() There are two ways to practically observe the first day of Spring. September Equinox – First Day of Spring in Southern HemisphereĪn Australian beach In January, A month which is considered the coldest one in the northern hemisphere/Credit: Conde Nast Traveler On the other hand, due to the earth’s tilt, the equinox that occurs in September in the northern hemisphere is the Fall or Autumn Equinox. Marks the first day of fall, therefore, Fall Equinox.įrom the above comparison chart, it is clear that the equinox that occurs in September in the southern hemisphere is the Spring Equinox. Marks the first day of spring, therefore, Spring Equinox. It marks the first day of summer, therefore, Summer Solstice. It marks the first day of winter, therefore, Winter Solstice. In the northern hemisphere, it marks the first day of spring, therefore, Spring or Vernal Equinox. In the southern hemisphere, it marks the first day of fall, therefore, Fall or Autumn Equinox. Or, the first day of spring in the southern hemisphere is actually the official first day of spring or not? Therefore, I would suggest you stick with me till the end. ![]() Moving ahead, in this article, we will talk about some of the exclusive facts like why there is a mismatch between the north and south equinoxes. CONFUSED? Don’t worry, we will talk about it in a later section. Regardless of the fact whether you are living in Newyork (northern hemisphere) or Sydney (southern hemisphere), the length of the day and night are almost exactly equal on the eve of the Equinox. In other words, the meaning of the Equinox changes depending on the fact that at which side of the earth you live. On the other hand, for the people living in the northern hemisphere, this Equinox marks the arrival of the official first day of fall in the northern hemisphere. In 2023, the official first day of spring in Australia (southern hemisphere) will occur on Saturday, September 23, at sharp 16:50 Australian Eastern Standard Time (AEST). That’s why in the earth’s southern areas, the September Equinox is known as the Spring Equinox. The seasons are defined as spring (March, April, May), summer (June, July, August), autumn (September, October, November) and winter (December, January, February).September Equinox marks the arrival of the first day of spring in the southern hemisphere. By the meteorological calendar, spring will always start on 1 March ending on 31 May. These seasons are split to coincide with our Gregorian calendar, making it easier for meteorological observing and forecasting to compare seasonal and monthly statistics. The meteorological seasons consist of splitting the seasons into four periods made up of three months each. Meteorological seasons are instead based on the annual temperature cycle and measure the meteorological state, as well as coinciding with the calendar to determine a clear transition between the seasons. This year, astronomical spring began on 20 March 2022 and ended on 21 June 2022.įor upcoming years, the dates for astronomical spring will be: Year Since the seasons vary in length, the start date of a new season can fall on different days each year. This is due to the 23.5 degrees of tilt of the Earth's rotational axis concerning its orbit around the Sun. Astronomical seasons refer to the position of Earth's orbit in relation to the Sun, considering equinoxes and solstices.
