Gujarat Experiences Rare Temperature Drop Amidst Post-Monsoon Rains
Imagine Gujarat experienced a surprise weather party!
Usually, October days get cooler after the rainy season ends.
But this time, it rained for many days straight because of some weather brewing in the sea.
This rain made the daytime temperatures drop a lot, much cooler than usual for October.
At the same time, the nights didn't get as cold as they normally would, staying a bit warmer than average.
This mix of cooler days and warmer nights is quite unusual and happened because the clouds from the rain kept the heat from escaping at night and also blocked the sun during the day.
Gujarat saw maximum temperatures drop by nearly 10 degrees Celsius below normal.
Minimum temperatures rose by approximately 5 degrees Celsius above normal.
The state experienced unusual weather due to continuous post-monsoon rainfall for five consecutive days.
A depression over the Arabian Sea is cited as the cause for the rainfall and temperature anomalies.
The gap between day and night temperatures narrowed significantly, with minimum temperatures staying high due to cloud cover.
- Who
- Gujarat residents and the India Meteorological Department (IMD)
- What
- Experienced a rare and significant drop in maximum temperatures (nearly 10°C below normal) and a rise in minimum temperatures (about 5°C above normal) due to continuous post-monsoon rainfall.
- When
- Friday (specific date not mentioned, but ongoing for five consecutive days prior)
- Where
- Across Gujarat, with specific readings from Ahmedabad, Rajkot, Amreli, Vadodara, Surat, and others.
- Why
- A depression over the Arabian Sea caused continuous post-monsoon rainfall and cloud cover, preventing temperature from dropping significantly at night and suppressing daytime highs.
Official Explanation
Observed Phenomenon
Temperature Trend
Official Explanation
Maximum temperatures dropped nearly 10 degrees Celsius below normal; minimum temperatures rose about 5 degrees Celsius above normal.
Observed Phenomenon
Maximum temperatures were below 30°C (e.g., Ahmedabad 25.5°C, Rajkot 25.9°C) and minimum temperatures were between 20.5°C and 24.5°C (e.g., Gandhinagar 20.5°C, Ahmedabad 22°C).
Unusual Nature
Official Explanation
IMD officials described the temperature drop as 'not such a common phenomenon' for October.
Observed Phenomenon
The unusually small gap between maximum and minimum temperatures (4-5°C) was highlighted as another uncommon feature.
Cause
Official Explanation
Continuous post-monsoon rainfall for five days due to a depression over the Arabian Sea.
Observed Phenomenon
Clouding prevented heat radiation at night, keeping night-time temperatures high, and also affected daytime temperatures.

- Temperature Gap
- Unusually small gap (4-5°C) between maximum and minimum temperatures
- Reason for Anomaly
- Post-monsoon rainfall and cloud cover due to a depression over the Arabian Sea
