What's the weather like mid-August? That's when I'm planning on going (if I do go), around August 12th-20th.
Last year around that time the weather was nice on some days and not so nice on others, it can be a bit unpredictable.
Shouldn't be cold but might not be sunny. It could turn out really nice though.
The weather over here is usually nice for a period of a time, then not so good, then better again etc etc.
