Hey, I was in Spiti from 24th July till 3rd Aug amidst all the cloud bursts and landslides. Even though we were safe throughout and did not encounter any difficulty still would like to suggest you avoid till the ongoing monsoon.
I think the rains would settle in the next 10-15 days and then your dates would be good to go.
You can visit Bhandardara, a beautiful place to spend weekend in Maharashtra. In Bhandardara you can visit Umbrella Fall, Wisdom Dam, Randha Falls, Kalsubai Peak and many more places. If you are planning to come The Yash Resort is the best place to stay. There they have swiming pool and an awesome pool side cafe named YOLO Cafe.
