IMD Issues Heatwave Alert for Bengal as Temperatures Soar

Eastern India braces for intense summer conditions as climate scientists warn of worsening extreme weather patterns

Kolkata, May 9:

The heat is arriving earlier.

And it is staying longer.

The India Meteorological Department has issued fresh heatwave alerts across multiple eastern Indian states, including West Bengal, warning that temperatures are expected to remain significantly above seasonal averages over the coming days.

Several districts have already recorded sharp daytime temperature spikes, while humidity levels are making outdoor conditions increasingly uncomfortable and dangerous.

For many residents, especially in urban areas like Kolkata and industrial zones around Haldia, the heat no longer feels like a temporary weather event.

It feels relentless.

Meteorologists say dry northwesterly winds, delayed pre-monsoon activity, and broader climate instability are contributing to the current conditions. In some locations across eastern India, temperatures are expected to cross 40 degrees Celsius during the peak afternoon hours.

But the bigger concern is not just temperature.

It is duration.

Heatwaves in India are becoming longer, more frequent, and more intense.

Scientists have been warning about this pattern for years.

Now it is becoming difficult to ignore.

What Counts as a Heatwave

According to IMD standards, a heatwave is declared when temperatures rise significantly above normal seasonal levels, especially in plains regions where daytime temperatures exceed dangerous thresholds.

However, climate experts say modern heatwaves are no longer measured only by thermometers.

Humidity, urban construction density, concrete heat retention, and nighttime temperature persistence now play a major role in determining health risks.

That is especially true in densely populated cities.

“In many Indian cities, people are not getting relief even after sunset,” said a climate researcher based in Kolkata. “The body never fully cools down.”

That increases risks for elderly citizens, outdoor workers, children, and people with existing health conditions.

Why Bengal Is Vulnerable

West Bengal faces a particularly difficult combination of factors during extreme heat events:

• High humidity

• Dense urban zones

• Coastal weather instability

• Heavy industrial activity

• Crowded public transport systems

In Haldia and surrounding industrial areas, workers in refineries, ports, warehouses, and transport operations often face direct exposure to high temperatures for extended periods.

Labour groups have repeatedly demanded stricter heat safety protocols during extreme summer conditions.

Heat stress is no longer viewed only as a health issue.

It is becoming a workplace safety issue too.

Electricity Demand Rising Sharply

The heatwave is also putting pressure on power infrastructure.

Electricity demand has surged across several states as households and businesses increase air-conditioner and cooling usage. Power distribution companies are closely monitoring consumption patterns to prevent local outages during peak evening hours.

Energy experts say India’s cooling demand could rise dramatically over the next decade if heatwaves continue intensifying.

That creates a difficult environmental contradiction.

More heat leads to more electricity consumption.

More electricity demand often increases fossil fuel usage.

And fossil fuel emissions worsen climate change further.

The cycle feeds itself.

Health Risks Growing

Doctors are already reporting increased cases of:

• Dehydration

• Heat exhaustion

• Dizziness

• Blood pressure fluctuation

• Heatstroke symptoms

Public hospitals in several districts have issued advisories urging people to avoid outdoor exposure during peak afternoon hours.

Authorities are especially concerned about daily wage workers, delivery riders, construction labourers, traffic personnel, and street vendors who often cannot avoid direct sun exposure.

For poorer households without reliable cooling systems, survival itself becomes physically exhausting during severe heat periods.

Climate Change Is No Longer Abstract

For years, climate change discussions often felt distant to ordinary people.

Now the effects are personal.

Longer summers.

Warmer nights.

Erratic rainfall.

Water stress.

Cyclones becoming more unpredictable.

These are no longer future warnings.

They are present realities.

India recorded multiple severe heatwave events over the past few years, with scientists increasingly linking extreme temperature trends to global climate disruption caused by greenhouse gas emissions.

Urbanisation has intensified the problem further.

Concrete-heavy city expansion traps heat, reduces green cover, and creates “urban heat islands” where temperatures remain higher than nearby rural regions.

Kolkata is already experiencing those effects.

Agriculture and Food Concerns

Heatwaves also threaten agriculture.

High temperatures can damage standing crops, reduce soil moisture, and increase irrigation pressure. Farmers in parts of eastern India are already expressing concern about water availability if pre-monsoon rainfall remains delayed.

Vegetable prices often rise during prolonged heat periods because transport, storage, and crop productivity become affected simultaneously.

That means climate stress eventually reaches household kitchens too.

Authorities Issue Public Advisory

The IMD and state authorities have advised citizens to:

• Stay hydrated

• Avoid direct sun exposure during afternoon hours

• Wear light clothing

• Reduce strenuous outdoor activity

• Check on elderly family members regularly

Schools in some regions are also reviewing outdoor activity schedules due to rising temperatures.

Meanwhile, environmental groups are pushing for long-term urban planning changes, including:

• More tree cover

• Heat-resistant infrastructure

• Public cooling centres

• Improved water systems

• Sustainable urban design

Experts say India can no longer treat heatwaves as occasional emergencies.

They are becoming part of normal climate reality.

And that reality is arriving faster each year.

For now, Bengal waits for pre-monsoon relief.

But until temperatures fall, millions will continue adjusting daily life around one unavoidable fact:

The climate is changing.

And the heat is becoming harder to escape.
