I've lived out west (CO) and I've spent time in Vegas, but it's been a while for both.
It's totally different here, so I don't know what I'd compare.
We obviously have high humidity here - it's sometimes a blessing, sometimes a curse. I'd take Florida's humidity over Summer in Vegas any day though - I could not believe how deadly hot it was (and I was dehydrated no matter how much water I drank

). Your skin will appreciate the move to FL

Bug Heaven here, but you get used to it. The weather is predictable enough - it's either raining or it's not, but either way the sun is shining

.
We do get a lot of people who move to Jax from San Diego (must be a Navy thing?), I guess they like it here?
