The Mumbai monsoon in one paragraph

Mumbai's southwest monsoon usually breaks around 10 June and withdraws in early October. Peak rain is July into early August, when the Arabian Sea branch of the monsoon slams the Konkan coast. Long Period Average seasonal rainfall for the city is roughly 2,200 mm, most of it delivered in intense bursts over a handful of very wet days.

Why the monsoon matters day to day

  • Local trains: Heavy rain plus high tide floods tracks at Kurla, Sion, Dadar, Hindmata and the Andheri subway, cutting Western and Central line services.
  • Waterlogging: Low-lying areas hold water fast when downpours land on a high tide window.
  • Health: Mosquito-borne illness (dengue, malaria) and leptospirosis risk climb through and just after the season.
  • Air quality: The one silver lining. Monsoon rain washes the air; June to September is typically Mumbai's cleanest AQI.
