Summer.
The beach is amazing. I love the sun, sea, sand and eye candy...not that I stare or anything. And the nights are more tropical and and and you can do more outdoorsy things and the nightlife perks up tenfold and if it's doing a good job, Summer is a party pill in itself.
Yet all that happens during winter is people get cold and depressed and binge on retail therapy. We don't get snow
So I say bring on summer.
