The timing of the birth of the future monarch was on everyone's minds today as the nation waited on tenderhooks for the little Prince's arrival. After the announcement that the baby boy arrived at 4.24 today, we now know he is a Cancerian, like his father Prince William and grandmother Diana, Princess of Wales. Astrologers predicted that if the Duchess of Cambridge had a lengthy labour, the Monarch could be a feisty Leo rather than an emotional Cancerian. Had he been born after 4.54 today, the child would have been a Leo, like its great aunt Princess Margaret, Countess of Snowdon, and Princess Anne. Scroll down to watch video . He's a Cancerian! Just like his father and grandmother, the Royal baby narrowly avoided becoming a Leo. If he had been born just half an hour later, we could have had a very different kind of Monarch . The Duchess of Cambridge went into labour at 5.30am this morning - with many suggesting the  approaching full moon at 11.16am helped bring on the contractions. Prince William was by his wife's side at the private Lindo Wing of St Mary’s Hospital in Paddington, west London, where he himself was born in 1982. Astrologer with The Association of Professional Astrologers International, Deike Begg, says the timing of the baby's birth this afternoon plays a huge role in his personality type. She said, as a Cancer, the baby should be . sensitive, caring, shrewd, family oriented and protective of their loved . ones. She said the baby's moon will be in Capricorn - which is the same star-sign as his mother. 'This means the baby will share a lot of the parents' personality traits. Different personality types: Diana, Princess of Wales, pictured left at a Live Aid for Africa concert in 1985, was Cancer, while Princess Margaret, pictured in 1960, was a Leo . 'As . a Cancer, the child will be very family oriented like its parents and . sensitive. Cancers often appear strong on the outside but are very soft . on the inside. 'But with a Capricorn moon it would also be aware of its responsibilities and dependable.' Traditionally . those born under the star-sign of Cancer arrive between June 22nd . and July 22nd although the exact dates vary slightly every year. Famous . Cancers include South African president Nelson Mandela, Hollywood . actors Harrison Ford, Tom Hanks and Tom Cruise, and Edward VIII, who . gave up the throne for American divorcee Wallis Simpson.

Astrologer Patrick Arundell said the . future king or queen will be more conventional because it is a . Cancerian, but would have been more of a ground-breaker if he was born . tomorrow as a Leo. Mr Arundell said the baby would also have a lot of 'go-get energy' and star quality. 'Mars . and Jupiter are conjunct in Cancer and that will give the baby a . tremendous amount of go-get energy and that is already in motion,' he . said. He added: 'Venus . and the Sun are also in a magnetic connection which will give the baby a . star quality and a sparkling charisma.' Meanwhile there have been numerous theories as to what caused the Duchess of Cambridge to go into labour - whether it was the full moon, an electrical storm or just conventional 'Baby Mean Time'.

Jokinen, of the Royal College of Midwives, said midwives often talk of . how the full moon makes for a busy spate of deliveries. 'It's . always sort of been an old wives tale saying that the full moon brings . women into labour. Midwives usually do say "I'm on call. It's a full . moon. I'll be busy tonight",' she said. 'There . was a study about 20 years ago at a hospital near the River Thames . which is a tidal river and it showed that on the full moon they did have . more births. 'The idea . is that because the baby is surrounded by water, the time of the full . moon and the high tide causes the waters to break. But there's not enough scientific evidence to show it's proven.' Birth . coach Zara de Candole, of Doula UK, said: 'As a doula (birth coach) who . has supported many women in labour, there does seem to be some link . between labour kick starting and a full moon.'

Chris Burton, a forecaster with MeteoGroup, the weather division of the Press Association, said: 'The storm affected western central London. There were lightning strikes at around 6am and very localised, intense heavy rain and thunder. 'We've had high pressure with the sunshine but now there's low pressure and it's hot and humid which can cause thunder storms.' Mervi Jokinen said she had not seen a connection between labour and electrical storms. 'We are full of electrolytes but I don't know. it's not something we've discussed as a midwific community. I can't vouch for that,' she said . She added that babies also arrived to their own agenda and their own time scale and put in an appearance when they are ready.
