A monsoon in May

by

Why have the rains arrived early in India?

1. Early Monsoon Arrival in Key States

Maharashtra (Mumbai):
The monsoon arrived 10 days early this year, hitting on May 25 instead of the usual June 5. In fact, this marks the earliest onset in 35 years—since May 20, 1990.

Kerala:
Similarly, Kerala experienced an early monsoon, with rains arriving on May 24—the earliest since 2009. Normally, the monsoon reaches the state by June 1.

Other Regions:
Meanwhile, the monsoon has already advanced into Lakshadweep, Karnataka, Goa, and parts of the Northeast (including Mizoram, Manipur, and Nagaland).

2. Impacts of Heavy Rainfall

Mumbai:

  • First, heavy rains caused severe waterlogging, disrupting traffic, flights, and local trains.

  • In particular, low-lying areas like Dadar, Parel, and King’s Circle were completely submerged.

  • As a result, airlines like SpiceJet and Air India issued advisories, warning passengers of delays and cancellations.

  • According to IMD data, Colaba recorded 135 mm of rainfall, while Santacruz saw 33 mm.

  • Consequently, the IMD issued a ‘yellow alert’ for Mumbai, forecasting gusty winds up to 40 kmph.

Kerala:

  • Here, the downpour uprooted trees, flooded homes, and damaged crops.

  • Due to the extreme conditions, tribal families in Wayanad had to be evacuated to relief camps.

3. Why the Early Monsoon?

Several factors contributed to this early onset:

  1. Madden-Julian Oscillation (MJO): This eastward-moving weather system enhances monsoon activity.

  2. Mascarene High: A high-pressure zone in the Indian Ocean that strengthens monsoon winds.

  3. Monsoon Trough: An elongated low-pressure area that boosts rainfall.

  4. Neutral ENSO (El Niño–Southern Oscillation): Unlike El Niño, which weakens monsoons, neutral conditions support normal/strong rainfall.

  5. Reduced Himalayan Snow Cover: Less snow may have accelerated heating, aiding monsoon advancement.

4. Benefits of Early Monsoon

Despite the disruptions, the early rains bring key advantages:

  • Agriculture: Farmers can start sowing summer crops (rice, pulses, oilseeds) earlier.

  • Water Reserves: Aquifers and reservoirs replenish ahead of peak summer.

  • Economic Boost: Sectors like fisheries, livestock, and hydropower benefit.

Passive Voice Note

The text still has some passive constructions (21.3%), such as:

  • “Railway tracks and low-lying areas were submerged.”

  • “Families were evacuated to relief camps.”

While passive voice is useful in some cases, active voice is generally clearer.

Final Takeaway

Overall, the early monsoon brings both opportunities and challenges. While flooding has caused disruptions, the IMD attributes the early arrival to favorable weather patterns, suggesting a potentially strong monsoon season ahead.
