We’re having such a nice weather these days! Even if we are in March, climate conditions are improving, winter is getting to the end and spring is about to start!
The expression March comes in like a lion and goes out like a lamb defines the weather, since the month usually starts with cold and rainy weather and ends warm and mild (literal translation: Marzo viene como un león y se va como un cordero).
You can also use just one part of the saying, as below:
– It is really cold, March is coming in like a lion this year!
