I like realism in my games to some extent, but the amount of rain in the fall, way, way, way too much. So far I''ve had more rain than clear days, which means less time at the fair. Have gone there a couple of times and it is empty except for one or two sims, it seems they don't like the rain either.
So, can I change the amount of rainfall, how many days, how long it rains? Can the temperatures be changed, say from being 25 degrees F to 40 F? For me, average in Fall is mid 30s to mid 60s day and mid 20s to mid 40s at night at the start. Further into the season, the temps drop pretty fast, but not at the beginning.
As much as I can't stand winter, it is easier for a sim to go out in the snow with warm clothes, gloves and play in the snow. With rain, all I get is cold moodlets, even with the umbrella they seem to get the soaked moodlet. Changing clothes when they go insides fixes that; but that doesn't help at the fair.
