Chag Sameach Rebbe, I hope you enjoy Succot and may we all be in Yerushalaim to see the Beit HaMikdash bm"b. Also, my cousin raised a question; we sepcifically sit in a succah now becasue it's nots so nice at as opposed to nissan when it is nice out. But when it rains, which is a norm for this time of year, it is a siman rah and we are patur from sitting in the succah. So why do we celebrate Succot now at the beginning fo the rainy season if we are putting orselves at risk of encountering this siman rah?
It's a good question, to which I never really paid any attention. I think that the logic is that the lack of rain is thus clearly indicative of Hashgocho, as would not be the case at another time of year.
