I have noticed that the best weather is typically first thing in the morning, and we have had non stop beautiful fireworks evenings every day this week. EP of course (minus show case) is the easiest for too hot, too cold, too wet weather, altho TT can get shut but not much else.
Living in the panhandle south for 5 yrs, than 7 W KY and now in C FL, you get used to summer/fall weather that is downright scary at times. (Altho I think for me, W. KY took the number 1 scary spot.) Anyway, when we would travel for cruises or FL trips, we would always choose last week Feb/Early March, April or May. Less winter weather, no real tropical weather yet. Any time outside of that, especially Sept/Oct (smack dab in active tropical season, Katrina was Sept, our Ivan was Oct) I personally would not plan a special trip myself. In fact, I haven't been down here in the fall I don't believe since probably 1998. (But we have come mid to late Nov and that has been winter weather already, even here...)
If all you have for the year is one week, its iffy. Now that we live down here, its different because if it rains for a week, we just hang out until it blows over. (Unless you get stuck at the grocery store in a whiteout, which did subside after about 30 min.)
I will say that it has definitely been cooler temps. I was grateful to have had my poncho on Sat, and someone described them as steamy and sweaty and it did actually keep me warmer.
Also, FYI the weather apps here really do change every few hours. I definitely would not trust a 5 or 10 day forecast.
On Sat, as it was raining like crazy and we were debating to go to the park on Sat or Sun, Sun said it was going to top out at 17% chance of rain, which is great. An hour or two later when I looked again, it was over 50 and when I got up in the morning, under lots of cloud cover, got a great run in though, and the weather said 100% chance of rain. It ended up being much worse than the Sat forecast even though it was supposed to look much better half a day before. We were glad we had stuck it out on Sat. Case in point, unless you have a tropical system (and we even didn't get nearly as much rain as they said we would last week), don't change your plans a whole lot, just do the best you can with it.
See some of the inside shows and then ride ride ride after it subsides because the die hards stay, every one else leaves.
