I would second cntryboy0531's advice. Except if you run in the morning the cement or asphalt has not had time to heat up so in addition to the air being a bit cooler so is the running surface. When I was working mids in Florida I would see many people running before the sun came up.
If you insist on running in the evening expect your times to be much slower. The heat and humidity will zap you, until you are used to the heat. I read an article a while back about Olympic runners going to the hotter/humid climates to compete. They would start a few months out running in the heat and humidity to acclimatize.
But when a long train of abuses and usurpations, pursuing invariably the same object, evinces a design to reduce them under absolute Despotism, it is their right, it is their duty, to throw off such Government, and to provide new guards for their future security.
Translation for the intellectually challenged: If the government screws the people too much, it is the right and duty of the people to revolt and form a new government.
