I am also getting the sense that there is too much rain in the game. I thought it was just me, until I read the comments on this thread. I have been playing mainly in Brindleton Bay (two-week-long seasons) and it seems to rain there more often than not, even in summer. I got tired of it, so I moved my sims to San Myshuno, but the weather is no better there either. I have also tried playing another household in Windenburg to see what it is like there, only to find that it rains almost every day. For the first time ever, I am seriously thinking of moving my sims to the desert!
