I do like it when April comes around, I really feel as if Spring is properly underway with the sun climbing ever higher in the sky and the evenings drawing out after the clocks change to British Summer Time.
It is the month that we see most of the plants and hedgerows bursting into life and the birds starting their annual courtship. April 14th is Cuckoo Day when their first call of the year is often heard, followed on the 15th by Swallow Day and the promise of long lazy days of Summer to come – we hope! But beware, April can always plunge us back into the dead of winter without any warning.
“March winds and April showers bring forth May flowers”, is a proverb we are probably all familiar with. But why do we get these classic ‘April showers’? One of the major reasons is the position of the jet stream. A band of very strong winds at around 30,000ft above the surface of the Earth, the jet stream controls the weather that we see on the ground.
High and low pressure systems are formed when the air in the jet stream speeds up or slows down. In early spring the jet stream starts to move northwards allowing large depressions to bring strong winds and rain in from the Atlantic. In one day the weather can change from springtime sunshine to winter sleet and snow.
April can bring all types of weather from sunshine to thunder, from fog and frost to mild muggy and drizzly days. The lowest April temperature for the United Kingdom is a dreadful minus 15°C on April 2nd 1917 in Cumbria – can you imagine?! And then again, it can become very warm with a record temperature recorded in London of 29.4°C on the 16th April 1949.
Cuckoo Day on April 14th is also St.Tiburtius’ Day – not a saint I have come across before. There is a very odd superstition that says if you hear the cuckoo sing on St.Tiburtius’ Day you should turn over all the money in your pockets, spit(!) and not look at the ground. If you do this and are standing on soft ground when you do it, you will have plenty of good luck. However, if you are standing on hard ground, the cuckoo’s call means bad luck. Um, I think I will pass on that one and just enjoy listening out for the cuckoo and its unique call.
