Average annual precipitation in Seattle, Washington: 38.25 inches
Average annual precipitation in Gainesville, Florida: 48.36 inches
Now, granted, Seattle gets its precipitation over an average of 154 days per year, while Gainesville gets its precipitation in larger but less frequent doses (116 days per year).
But, then again, close to a third of Seattle's precipitation is snow, it has 1/10th as many thunderstorm days as Gainesville and severe thunderstorms seem to be unknown in Seattle while Gainesville averages seven severe thunderstorm watches per year.
So I'd say "The Sunshine State" -- or at least this part of it -- qualifies as objectively rainier than Seattle, which has a reputation for being rainy.
No, I'm not complaining. I love Florida, and I love the rain in Florida. It's coming down outside right now. Not cats and dogs, but a steady, fairly heavy drizzle. Very nice indeed.
