Mumbai – India’s financial center, Densely populated Indian city, was getting ready to brace its first cyclone in 129 years. Yes, it’s all about cyclone Nisarga.


Indian Meteorological Department had declared about cyclone Nisarga which was forming into a severe cyclonic storm in the Arabian Ocean. And predictable landfall would be near Mumbai and neighboring Thane, Raigad, Ratnagiri, and Sindhudur.

Let’s have a look upon some interesting facts below which discusses Nisarga and Mumbai’s cyclone history. 

Mumbai cyclones

MUMBAI experienced severe floods in recent years, but none was due to cyclones.

Mentioned below are the list of recorded storms in history so far –>

Great Bombay Cyclone - June 6th, 1882.

  • Approximately 100,000 death cases were reported which was almost 1/8th of the total population of Mumbai at that time. 
  • This was recorded among the dangerous cyclone by many authors. 
  • But there are many contradictions to this fact. Researchers consider this as just a myth and an internet hoax.
  • There are some pieces of evidence that proves no cyclone in the mentioned year. The below image by IMD is one such evidence which shows no such cyclone occurred during the mentioned year.

Bombay cyclone - 15th to 23rd November, 1948

  •  This had its landfall in Mumbai Colaba (Gusts 129 km/hr), Alibag (Gusts 160 km/hr), Mumbai Juhu (Gusts 151 km/hr).
  •  “The Cyclone had brought sea into the land”, a Portuguese traveler explained this cyclone using these words.

Arabian Sea Tropical Cyclones

Cyclones are rare in the Arabian Sea comparative to the storms formed from the Bay of Bengal. This sea is less prone to storms because the water temperature is less than that of the Bay of Bengal. Most of the strong tropical storms formed on its basin don’t reach high intensity due to the dry air coming from the Arabian Peninsula desert and adverse wind shears.

Maximum number of Arabian sea cyclones moves towards Middle-East countries.


But this time it moved towards north-east Maharashtra due to a ‘rise in temperature of the Indian coastal water.’

Due to the adverse climate changes happening around us, there would be  rise in cyclonic storms over the Arabian Sea in the future.
