The season is a factor, there's different weather sets for those things (english summer, etc).
Ok one more hit of the deceased equine: if you pick "real world data" and have an option to set tours at any time of year somebody at the design phase has to ask "what if some douchebag tries to play cricket in winter?" and the answer to that cannot be "we'll pretend it's summer" otherwise there is no point in the option.
And the real world data is wrong. In England, there are clouds nearly all the time, even in summer. Also, it generally rains now and again...
