Yes it's gonna be raining. I'll suggest you to choose a place with a view for your workation so that when you wake up you have a beautiful view to look at through your window. Working constantly on your laptop will stress your eyes but a beautiful view will be a treat to your eyes since you won't be able to step out of your stayplace atleast till 5 pm I guess. I'll suggest places with mountain or snows as it makes a great view to me.
Hey Komal,
I went to Goa during 20th August for a week or so.. since it is the monsoon season, watersports and even a lot of beach shacks would be closed bcoz of rains. However, the weather is usually pleasant and it doesn't always keep raining and since you are going to workation, I am assuming you would have few hours a day to explore so I believe you can totally go for it. If you are somebody who is ok with rains.. You can still explore good cafes, go for a walk at the beach, if you are someone who enjoys 'Me' time or less crowdy places, then it's a perfect time. Do confirm about the powercuts or availability of good wifi at the place you are planning to stay before leaving..
