I would suggest you Goa...I know people will say that you should go with friends but trust me it's my personal experience. July is off season for Goa like place and since the rain has just started you will love how beautiful Goa becomes during this season. Enjoy ur solo ride through narrow roads surroundings lush green fields and palm trees. You will surely live it.
Try Kerala .. you would love the night life at varkala cliff ... visit munnar thekkady alleppy and then head to kanyakumari which is just 100 kms from the capital city of Kerala
If you want to go to France but don't have the money yet, go to Puducherry instead! With French influence in its architecture, this sleepy little place is perfect for a serene, beach getaway. The food has a lot of French influence too and beer is cheap, making it a place to if you want a real culinary experience. The Auroville temple is a place to visit if you want to reconnect with your spiritual side.
You can try places in Rajasthan such as Jaipur, Udaipur, Jodhpur in the month of July for solo travelling.
Zostel is also there in these places for your stay.
