Pregnancy in Florida

I know personally understand what women talk about when they say it's easiest to be pregnant in cooler climates. I currently live in florida, and i'm 18 weeks. it's May & hot & humid. Physical activity is an important part of life, and pregnancy, well this may even be more of a reason to get moving. Going to the store during the day, a simple 15 min drive - me being passenger, is exhausting. My beloved sunday trips to the famers market down the block is something I'm not sure i'll be doing again any time soon. With tropical storms comeing around the ocean is turbulant, so my calm morning swims are few and far between - I'm on the look-out for a natural pool (I do not want to swim in chemicals), so if you know of one in southeast florida please let me know.
If I wake up early enough I take a walk with my husband at the beach, luckily that is just steps away. And in the evening, we walk a few blocks to the juice bar, sometimes walk around the beach also. That is the extend of it. I'm dreaming on california air & mountains, hiking with the smell of redwoods and euciliptus.

To balance is out I'm looking into prenatal yoga classes & possibly some belley dancing classes. Our living situation at the moment is a bit limited on space, so doing excercise of any sorts here is not appealing to me at all. Well see how it goes. I do have a feeling a move is coming for us very soon, i'm just not sure if that's going to take us to cooler climates.
