When does Spring start and what is the equinox?

The equinox marks the start of spring, which occurs on Wednesday 20th March.

An equinox is an astronomical event in which the plane of Earth’s equator passes through the centre of the Sun.

On an equinox, day and night are of approximately equal duration all over the planet – a day and night of roughly 12 hours each.

The Equinox in the Northern Hemisphere occurs twice a year around 20 March (the spring equinox) and around 22 September (the autumn equinox).

The spring equinox marks the beginning of Spring and from this day forward the day is longer than the night.

With the arrival of spring on Wednesday temperatures will feel like the season has arrived.

High pressure will draw up warmer air towards the UK and by mid week the region could see highs of 15C.

This will be a huge difference from last week when wet and windy weather battered the UK.

The high pressure will not only bring warmer temperatures, but the weather will be much more settled with lighter winds on Thursday.

Although warmer temperatures are forecast, the weather is expected to be mostly cloud across Merseyside, ruining chances of temperatures climbing any further than 15C.

The Met Office say: “Often cloudy with patchy rain possible, particularly over hills, with the best of any brightness in the east. Turning warmer over the period.
