I've lived in Dallas and lived in San Antonio but never found either one very hot, at least not to unbearable intensities. But when factoring in the humidity and direct sun experienced in Florida (and my native Louisiana), I'd say it's very hot and unpleasant in WDW at times. In fact, it rivals most other places in the US, save Death Valley and surrounding areas.
To say it is not that hot in Orlando is asinine, but this is just a friendly discussion right? I suppose 90 degrees in Michigan and Wisconsin (as it sometimes reaches there during a heat wave) is the same as 90 degrees in Florida? Weather Channel stats are irrelevant as air tempature is not a direct reflextion of how people "feel" warmth and "hotness", even when considering the heat index. There is no numerical way to gauge the intensity of "hot" weather other than individual comparison.
When I cut my grass on a 95 degree day, it's no big deal as long as there is cloud cover. But with no clouds and the beaming sun, it's as if Lucifer hath cast firery swaths of blazing demons upon the South. But I suppose we all have more important things to talk about than the weather, but I couldn't help myself on this one.
