The tulips are starting to bloom again

Spring has come rather early in these parts this year. The snowdrops were the first flowers and then the crocus and now the daffodils and narcissus, still mostly in bloom and the tulips are just starting up. 
I feel like holding onto this wonderful spring period as long as possible before the dreaded heat of the summer comes upon us!  It seems to me, that summers are getting hotter and more humid. Has anyone else noticed this?
