The anticipation of spring is also a lovely period. You know it will happen and one day soon, when I go out in the garden I shall be able to smell spring and then I will see small buds on the bushes and the trees.
We don't have such a great difference in the weather as you describe with hot and humid weather one day and frost on another day, but in the morning the fields are often white from night frost and during the day the temperature can raise 10 degrees or so.
