No, civileng68 ... I think you're wrong. There has never been a time in Florida history when central Florida has been hit by four hurricanes for 9 or ten years in a row. And I would pretty much bet my existence that there will not be four hurricanes to hit central Florida in each of the next 9 years. If that kind of thing were true, no businessman or banker in the world would have backed Disney if he built in Florida. I think you mis-interpreted your data. What the data means, I believe, is that according to those who do this kind of thing for a living, the pattern we are in now will mimic the pattern from the 1940s. You would have to check the Pacific activity after the last four-hurricane year and move through the next few years, following the water current and barometric pressure patterns that came about after that. Then you can approximate what will happen for the next several years.
To the OP -- there is no guarantee that any given month or week will be less active from a hurricane standpoint than any other month or week. July isn't "safer" than August. One year, it could all happen in July -- hurricanes, thunderstorms, brush fires, freak tornados -- the next year it could happen in August, the next year it could not happen at all.
Having just done a five-year weather tracking analysis for the WDW area, I can tell you that for the past five years, it has rained nearly every afternoon during the first two weeks of August, and it has rained nearly every afternoon during the last two weeks of July. About half of those rainstorms originated as or became thunderstorms. In the past five years, there has been one August hurricane to hit Central Florida, Hurricane Charley in 2004. He arrived in Orlando on the 13th. No hurricanes have hit Central Florida in late July for the past five years. If that helps the decision, great. But anything can happen, y'know? The best thing to do is to plan your vacation for when it's most convenient for you and not try to plan around the weather. Weather is too fickle.
