Sounds typical for noseeum's, also called biting midges, or in some places sand flies/ sand gnats. They are quite tiny and different people react differently to them, some say they hurt when they bite, others get a welt like a mosquito, sometimes persisting for a few days. Most people get a reaction like yours, little welts or spots that resolve in a half hour to 2 hours.

These are common all along both Florida coasts, particularly at dawn and dusk, and where there are mangrove swamps nearby. I've been bitten far from the ocean, too (few miles).

A good mosquito repellant will stop them for a while. Typically I make sure I have long pants, long sleeve shirt and socks when they are heavy. They are not as bad in the winter.

I suggest you take a very close look at your skin when exposed. They are smaller than a common gnat and sometimes very hard to spot.

Hope this helps!
