29th Night Post :

A W.D. has saved and prevented a "Major" heat spell.. In North India.

Check the 29th Day Temperatures below.. 👇

And the anomalies ( Variation from the normal👇


[This was expected.. ( writer only mentioned what he had read earlier)] 👇


29th April Reality vs Rumour – Ground Truth

🌡️ Actual Day Temperatures (29th April)
Core heat belt (Central India / Vidarbha): 42°–45°C
North India plains: 34°–38°C
Northwest (Punjab/Haryana): ~36°C
Peninsular India: 34°–38°C

➡️ Conclusion:
Yes, hot — but typical late-April continental heat, not extreme or unprecedented.

📊 Temperature Anomaly (Departure from Normal)
Max Temperature Anomaly
North India: -2° to -8°C (below normal)
Central India: 0° to +2°C (near normal to slightly above)
East India: -3° to -6°C (below normal)
Min Temperature Anomaly
North India: -2°C (cooler nights)
Central India: +1° to +3°C (slightly warm nights)

➡️ Key Insight:
👉 The “hotbed regions are NOT above normal”
👉 In fact, North India is significantly cooler than normal

⚠️ The Rumour vs Reality
What was circulated
Entire India shown in deep red
Impression: Extreme / unbearable / crisis heat everywhere
Emotional messaging: “Pain in the air”, “no relief”, etc.

What data shows
Mixed pattern:
Cooling in North India
Normal heat in central belt
No widespread extreme anomaly

➡️ Scientific Reality:
This is not a pan-India heatwave scenario
This is seasonal variability with regional contrasts

🧠 Vagaries Insight
“Colour is not climate truth.”

28th Post

 Dispelling "fake news" of impending 1) fatal heat waves to hit India, 

2) A"super El Nino"..

 A once in 150 years El Niñocoming this summer, 

3) Record temperature touching 55°c 

4) India is going to have an unlivable summer 

5) "This is only April, the hottest months are not yet here"... And more of these alarming and panic news circulating. 

>Like we said in the blog on 27th article, there is nothing so vastly unusual... 

> Some facts and actual early high temperatures in the past... Showing earliest 40°c in the past... And much earlier than this year.. (Ref : Vagaries Extreme Blog.) 

1953 . 28 -Feb Akola 40.0°c , Ahmedabad h28 Feb 40.6 °c, Baroda 28th Feb 40.6°

1963 -  23-Feb Bhubaneshwar 42.7c    

1973     28-Feb Ahmadabad, Baroda, Bharuch, Rajkot, Surat.Baroda 41.7c, Bharuch 42.8c

1974.     27th Feb Jalgaon 40°

1976      20- Feb Dohad 42.0c

1981      3-Mar Mumbai Scruz 40.0

  • February: In exceptionally warm years, parts
  •  of MaharashtraGujarat, and Telangana can hit 40°C by 
  •  last week of February. For instance, in 2023,
  •  several locations in Maharashtra and Gujarat recorded temperatures
  •  close to or at 40°C as early as February 12-16.

  • Pune recorded it's earliest 40°on 20th March 2006.

  • New Delhi Palam on 23rd March 2004.
  • In 2010, the first 45c touched on 10th. April, and on the

  • same day Nagpur was 44c, Delhi 42.8c. Soon on 15 th April
  • 2010, Nawabshah (Pakistan) soared to 47c,
  • Simla to 28.2c
  •  on 16th, Ganganagar, Akola and Hissar to to 46c. 
  • On 19th April 2017, first ever 50 c
  • temperature in April in
  •  Asia has been recorded at Larkana (Sindh).

  • And so on and on... So what's different or unusual in heating this year in 2026 ??

  • > Super El Niño scare: Current State: ENSO Neutral
  • Short-term: Neutral conditions likely to continue briefly

    Transition: Rapid shift towards El Niño expected (May–July)

    Probability: 61–94% chance of El Niño dominating later in 2026

  • So let us actually wait and watch. 


  • Conclusion : 1) Hyper blown up

  •  contravertial situations 

  • 2) Things and

  •  Temperatures not going to extreme

  •  unbelievably high 

  • 3) We need to be alert

  •  and cautious, not generating panic.
