Not to worry. Yes, there is almost always a pleasant breeze blowing. Many folks don't even use their AC. Just open the windows. Naturally, just prior to a storm the breeze may change direction or hit a lull. Or the storm may bring some stiff wind, but it's only temporary. Squalls and little storms are normal in the Caribbean, but infrequent.
Just have a wonderful time in the sunshine!
