April weather can be very odd. Last week we had temperatures approaching 25 degrees C. Today we have snow flurries!
When I first came to Cambridge in the early 1970s we did a 4m contest from the back of someone's Landrover. It was bitterly cold. I think it was April 3rd. Sometimes days can be very cold and other days very hot. In the UK in April, anything can be expected.
