There are at least a million retired people living in Florida. Most of them own small houses, mobile homes or condominiums in one of the many "Golden Age" communities scattered about the state. They typically spend their summers in the northern states visiting their children and grandchildren. Every Spring in April or May, these retirees pack up their belongings, close up their Florida home for the Summer and head north to the homes of their children and grandchildren in New York, Cleveland or Detroit.
They spend the summer months playing with their grandchildren, taking them to the beaches and parks, buying them ice cream and spoiling them. They help their children with gardening and housework. They keep the grandchildren occupied while their children go off to work.
At the end of summer, in September or October, these "snowbirds" begin their seasonal migratory return to their Florida homes. They may take a quick trip back up to the frozen northlands during December to further spoil their grandchildren with lavish Christmas gifts, but they otherwise spend the winter half of the year at their Florida homes, where they can relax around their swimming pools, play golf or tennis, or congregate with their Florida neighbors.
Thus, the permanent population of Florida decreases during the summer as the snowbirds head north, while the transient population of tourists floods into the state. Summer can be hot, humid, wet and miserable in Florida, and is considered by the residents to be the least desirable season. Nevertheless, most families with school-age children will travel to Florida during the June, July, August school holiday season. They will crowd the amusement parks, create long lines at the attractions and fill the beaches.
If you must go to Florida in the summer, here is what you can expect. It can get hot. Very hot. Not the dry desert heat of Arizona or Nevada, but a wet, humid heat of a steamy jungle. The midday sun will bake your head and burn your skin while your sweat will roll down your face and soak your clothes. Every afternoon, storms will roll in from the Gulf of Mexico, and amid flashes of lightning and clashes of thunder, will drench you with copious volumes of rain. By evening, it will usually calm down and cool down to become downright pleasant, except for the mosquitos, bugs, lizards and other vermine that creep out of the jungle.
You can still enjoy Florida during the summer months, if you follow these few simple tips, that were gifted to me by a long-time snowbird in Southern Florida.
First of all, awaken at sunrise and go to the beach or amusement attraction very early in the morning before the heat becomes oppressive. Start no later than 8AM and stay out no later than noon. Thus, you will get plenty of sun to create a golden tan without turning your skin lobster red. You will beat the crowds to the amusement parks and avoid waiting in the blistering sun to get on the most popular rides.
At noon, go to a comfortable air-conditioned restaurant for a leisurely lunch. Go shopping or visit some indoor attractions during the oppressive midday heat. Go to a waterpark and spend the hot afternoon in the water, or go back to the hotel for a mid-afternoon siesta. You will avoid the midday heat and most likely avoid the late afternoon thunderstorm.
After five or six in the evening, it will be safe to once again venture out into the sun. Hopefully, the afternoon thunderstorm will have cooled the temperatures a bit. You can go back to the beach for a sunset swim or stroll, You can go back to the amusement parks for the evening festivities without the oppressive heat. You can even golf, boat or play tennis in the cooler evening.
I tried following these tips when in Florida during a hot August, and found that they improved the quality of my vacation time quite a lot.
