Sweats, fuzzy things.
It WILL warm up. This is very unusual weather. And it's not that bad even right now if you think "spring" or "early fall".
It very much reminds me of August in cottage country in the north. It's hot in mid-day if the sun's out. And you can always go in the water if you're ok with the jolt of getting in. But early or late, I want my fuzzy sweat things.
We were at Mariscos Tinos two nights ago. There were lots of people there, having fun. But they were dressed for dinner at a hunting lodge (sweaters, windbreakers, sweats). Of course it's not that cold during the day, but, at night, right now, fuzzy cozy is the way to go.
My husband slept in his track suit last night.
It WILL change. But, if you can, be prepared.
