I am sorry I do not have that specific information. India is generally a very hot country so I would assume the same for this city. 
 According to Slate magazine, they said that "Bombay" was a corrupt version of the city referring back to the time when India was under English colonial rule. I do not know how much the people living there earn. 
 Thank you for all your help! 
 I do not know that specific information exactly, but the city was previously called Bombay until the name changed in 1996 and now when any name other than Mumbai is used in reference to the city, it has been a very controversial matter. 
 Oh yes, I've heard of Bombay! Wonder why they changed the name? Do you how most people earn a living? '
