"Take your brolly, it's chucking it down!" The UK is famous for its rainy weather, and Brits LOVE to complain about it – particularly when the arrival of spring teases us with warmth and light, but with them come the 'April showers', lovingly shared by Britain, Ireland and some of coastal northern Europe. What exactly are they, and why do they insist on coming every year?

Meteorologists differentiate between rain and showers. The UK's national weather service, the Met Office, says that rain is precipitation brought by a weather front, is usually long-lasting, and stretches over large areas, whereas showers fall from individual clouds and are characterised by intermittent patterns. So, it can be sunny one minute, and the next you're getting caught in a large downpour, but then ten minutes later, you can put away your waterproof jacket and get your sunnies out!

So, what's responsible? Rob Thompson, meteorologist at the University of Reading, says that as the hot air rises, it forms the cumulus clouds that produce showers. These are then driven by the jet stream – strong winds that move northwards during spring – creating rather unsettled and unpredictable weather. Besides the drizzle, we're just as likely to experience snow as we are to feel sun as strong as that in late August!

With all this in mind, would it surprise you to hear that April is actually one of the driest months of the whole year? In 2021, data company Statista recorded 137.6mm of rainfall in January, compared to just 20.1mm in April, with similar results for the last four years. That's because while there are lots of rainy days in April, the showers are scattered, and there aren't as many of the long downpours we see in the winter months. But, this is likely to change as the world warms up. Weather that causes flash floods is predicted to be four times as frequent in Britain by the 2070s, according to a study by Elizabeth Kendon and colleagues, published in Nature Communications.

There is a British proverb that goes "March winds and April showers bring forth May flowers". It is a reminder that, despite our complaints, April showers can be a symbol for renewal and new beginnings. So Brits, instead of complaining about the drizzly days, why not romanticise that pitter-patter sound that brings us the colourful spring bloom?
