You can visit South India during this season. Wayanad, Munnar, Chikmanaglur, Sakleshpur etc.
Beaches - Gokarna for less crowd . You can trek from Paradise Beach - Half Moon beach and Om beach. Water activities would be closed during monsoon. https://www.tripoto.com/trip/gokarna-a-more-relaxed-place-than-goa-5cffe4ede3c8f If you like Mountains - you can go to Himachal or Uttarkhand. But be safe, as the landslides would be more.
Itz depend. how many days u have for travel. if u want to travel on weekend then many hill stations near mumbai and pune are good options. if u have atleast 8-10 days then u can visit himachal or uttarakhand or kashmir. u can travel to spiti or leh or dharmshala or auli. all are very good options for you.
