Even if it did rain a lot in in June, a single previous years rainfall isn't a perfect guide to future patterns any more than it is at home. The fact is that from June to September it will be hot, humid and you will often see rain. That's just the way the climate is.

I'm actually in Florida now and yesterday it started to rain around 2.00 pm and was still pouring down when I went to bed around 10.00 pm. However, that was the first rain we'd seen since last weekend (although this weekend's forecast isn't great[msnsad]).
