Goa is a special place where you wish to be in all the seasons at all stages of your life. I have been there twice with friends during winters and I fell in love with the aura surrounding the place. I heard and read a lot about beauty of the place in monsoon but there were two kinds of reviews almost everywhere; one who suggested it as off season and another who loved it during monsoon.
When we stepped down at Thivim railway station it was raining heavily. One thing we knew about visiting Goa during monsoon is don't wait for rain to stop. Be ready to move and come prepare as it will rain all the time. We took out our rain coats, covered our bags and moved out to prepaid booth. During my previous trips I mostly stayed at hostels or any other cheap places while this time we opted for leisure resorts. Prices of resorts are at ground level during this season and you can unimaginable bargains at high end resorts. If you ever went to Goa during peak season you must be having an image of beaches filled with shacks, people sunbathing and surfing in water. You will not find any of those activities in rains. It will be secluded, serene and beautiful exclusively made for relaxing and exploring your inner self in peace and tranquility.
