As it happens in my playgroup, there is a very decent chance one of the players asks a question like this: What time it is? What's the weather like? What's the result of my Read Weather spell? What is the lunar phase this night?
Some of these questions might be friendly poking, but some of them are valid during the campaign. When unprepared, you can just make up the time /quite easily/,but coming up with weather patterns is about as fun as it sounds and don't think about screwing up with full moon just after announcing waning moon.
Soon I am about to start a Carrion Crown campaign. If you read the campaign, you might be familiar with S-man and his shenanigans, lunar phases might be a thing when the Broken Moon comes up, basically most of the adventure the party is moving outdoors from one county to another.
Yes, there are random tables weather or whatnot, but rolling bunch of dices in front of my player doesn't sound a lot like fun.
So I recently came up with this idea. To make things easier, I would make a weather chart, based on the historical weather archives. I could fill in all sorts of things, like above mentioned lunar phases, festivals and holidays, actions, that I know will come up (like the S-man)...
The question is, has anyone tried something like that? What sorts of information did you use? How well did it go? Was it well received by the players? Or is it something that is just a waste of time?
