Just answering this so I don't derail the conversation over on What's the Weather
Oh wow, I'm glad everyone is thinking more about online safety and the types of information they share! I do like the way you narrowed the information and came to that conclusion @Jacoby_Elderfun1.
But to the point of the question: Is this type of thing ok to share?
While Jacoby's narrowing down of information based on Weather reports alone is accurate the best information you are going to get is the state (for Americans), a lot more information would be required to find even the Town or suburb you live in. While I suggest not sharing what state you live in (if you can avoid it), it won't lead someone to your door.
The main things I would be worried about sharing online would be anything directly relating to the area I live in and personal information varying from online information to real life information eg, passwords, emails, school names, church names, that sort of thing.
My own personal rule when sharing any information is: be as vague as I can. Someone asks what the weather is like, my answer: oh it's pretty rubbish bit of rain here and there. Someone asks what it's like around where I live, Oh it's a pretty decent area, clean and tidy with some nice parks. That sort of thing but remember, if you don't feel comfortable answering something just say I would rather not answer that thanks, or something to that effect.
Something I would suggest everyone think about is what types of information you do/have/would consider sharing and could you narrow down where you are with that information alone?
Does that all make sense? If anything is confusing please let me know so I can help you out!
