Meteorological and astronomical seasons

Astronomical seasons refer to the position of Earth's orbit in relation to the sun taking into account equinoxes and solstices. 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.

Since the astronomical seasons vary in length, the start date of a new season can fall on different days each year. This makes it difficult to compare seasons between different years and resulted in the introduction of the meteorological calendar. This splits the calendar into four seasons of approximately the same length. The astronomical seasons run approximately three weeks later than those of the meteorological calendar.

Meteorological season

The meteorological seasons consists of splitting the seasons into four periods made up of three months each. These seasons are split to coincide with our Gregorian calendar making it easier for meteorological observing and forecasting to compare seasonal and monthly statistics. By the meteorological calendar, spring starts on 1 March.

The seasons are defined as Spring (March, April, May), Summer (June, July, August), Autumn (September, October, November) and Winter (December, January, February).
