Patna: Sultry and oppressive weather conditions continue to trouble residents across Bihar, with meteorologists warning that rising humidity levels are making temperatures feel significantly hotter than the official readings.
According to the Meteorological Centre Patna, the combination of intense sunlight and moisture-laden air has sharply increased the Heat Index — the “feels like” temperature experienced by the human body.
In several cities, although the recorded maximum temperature remains around 40°C to 41°C, residents are reportedly experiencing conditions equivalent to nearly 50°C.
Bihar Begins Monitoring Heat Index Alongside Temperature
The Meteorological Centre in Patna has now started issuing Heat Index figures along with standard temperature readings.
Officials said the Heat Index is calculated using:
- maximum air temperature
- relative humidity
- wind conditions
Meteorologist Sanjay Kumar said high humidity levels were significantly intensifying the sensation of heat.
“When humidity exceeds 50% and temperatures cross 40°C, the heat begins to feel extremely severe,” he said.
He explained that the body cools itself through sweating, but high atmospheric moisture slows the evaporation process, reducing the body’s ability to regulate internal temperature.
Patna Emerging As ‘Heat Island’
Officials also warned that Patna was increasingly exhibiting characteristics of an urban “heat island”.
According to meteorologists:
- concrete structures absorb and retain heat
- airflow within the city is disrupted
- easterly winds lose their cooling impact
This has created noticeable temperature differences between Patna and surrounding rural areas.
Experts added that climate change and shifting weather patterns were further amplifying heat stress across the region.
Major Gap Between Actual Temperature And Heat Index
Data released by the Meteorological Centre showed a substantial difference between recorded temperatures and perceived temperatures in several cities.
| City | Temperature | Heat Index |
|---|---|---|
| Patna | 33.6°C | 46.6°C |
| Gaya | 35.8°C | 49.1°C |
| Bhagalpur | 32.8°C | 42.7°C |
| Muzaffarpur | 31.4°C | 34.9°C |
| Darbhanga | 33.5°C | 42.4°C |
| Buxar | 36.0°C | 45.8°C |
| Aurangabad | 38.3°C | 48.0°C |
| Bhabhua | 41.1°C | 49.1°C |
Officials said Patna recorded humidity levels of around 73% on Friday, contributing to the intense discomfort being experienced by residents.
Public Advised To Take Precautions
The Meteorological Centre urged people not to rely solely on recorded temperatures while planning daily activities.
Officials advised residents to:
- avoid prolonged outdoor exposure during peak afternoon hours
- remain hydrated
- reduce strenuous activity in humid conditions
- pay attention to “feels like” temperatures rather than air temperature alone
Meteorologists warned that fluctuations in both humidity and temperature could continue over the coming days, prolonging uncomfortable heat conditions across Bihar.
