Karnataka Braces for Scorching Summer: Heatwave Alert Issued as Temperatures Set to Soar Above 40°C

Karnataka Braces for Scorching Summer

Karnataka is gearing up for an intense summer, with meteorologists predicting hotter-than-average temperatures and prolonged heatwave conditions across the state from March to May . The Karnataka State Natural Disaster Monitoring Centre (KSNDMC) and the India Meteorological Department (IMD) have issued alerts urging residents to take immediate precautions to combat extreme heat, which could pose serious health risks.

Heatwave Warning: Regions on High Alert

According to forecasts, north interior Karnataka and coastal districts are expected to bear the brunt of the heat, with temperatures likely to surge between 37°C to 39°C, potentially crossing 40°C in some areas. These regions could face heatwave conditions lasting anywhere from 2 to 14 days, with the first spells anticipated as early as March. Coastal Karnataka, including districts like Uttara Kannada and Dakshina Kannada, has already received IMD heatwave alerts for March 2–3, followed by hot and humid conditions on March 4–5.

In contrast, Bengaluru, south interior Karnataka, and the Malnad region may experience near-normal temperatures, though minimum temperatures statewide are predicted to remain elevated, exacerbating discomfort.

Health Advisory: Stay Safe Amid Rising Temperatures

The Karnataka Health Department has rolled out a detailed advisory to mitigate heat-related illnesses, emphasizing protection for vulnerable groups such as infants, pregnant women, outdoor laborers, and individuals with chronic health conditions. Key recommendations include:

• Hydration: Drink water frequently, even if not thirsty. Opt for Oral Rehydration Solutions (ORS), coconut water, lemon juice, or buttermilk.
• Diet: Consume water-rich foods like watermelon, muskmelon, cucumbers, and leafy greens.
• Clothing: Wear loose, breathable cotton outfits and use hats/umbrellas outdoors.
• Timing: Avoid outdoor activities between 11 AM and 4 PM, the peak heat hours.
• Workplace Measures: Employers must provide shaded rest areas, drinking water, and flexible schedules for laborers.

Prolonged exposure to extreme heat can trigger heat cramps, exhaustion, or life-threatening heat strokes. Authorities advise immediate medical attention if symptoms like dizziness, rapid heartbeat, or fainting occur.

Coastal Karnataka: Humidity Compounds Heat Risks

Coastal regions face a dual challenge of high temperatures (37°C–39°C) and humidity levels above 70%, creating a “feels-like” temperature far exceeding actual readings. The IMD warns that such conditions heighten risks of dehydration and heat stress, particularly for those working in fishing, construction, and agriculture.

Bengaluru’s Summer Outlook

While Bengaluru may escape the worst of the heatwaves, daytime temperatures in the city are expected to hover around 34°C–36°C, with minimal relief at night. Urban heat island effects, exacerbated by concrete structures and reduced green cover, could make certain areas feel hotter. Residents are advised to use energy-efficient cooling methods and limit outdoor exposure during afternoons.

Long-Term Preparations and Climate Trends

The KSNDMC attributes the rising frequency of heatwaves to climate change and shifting weather patterns. Over the past decade, Karnataka has seen a 15–20% increase in heatwave days, with ranking among the hottest years on record. The state government is collaborating with local bodies to implement heat action plans, including:

• Setting up cooling centers in high-risk districts.
• Distributing free ORS packets through primary health centers.
• Conducting awareness campaigns in rural and urban areas.

Conclusion: Vigilance Key to Surviving the Scorching Season

As Karnataka prepares for a grueling summer, adherence to health advisories and community-driven precautions will be critical. Farmers, daily wage workers, and street vendors—groups most vulnerable to heatwaves—need targeted support to avoid productivity losses and health emergencies.

“This is not just a seasonal challenge but a public health crisis,” warned a KSNDMC official. “Collective action, from individuals to policymakers, is essential to build resilience against escalating temperatures.”

With the IMD predicting an early onset of heatwaves, the state’s ability to safeguard its population, especially marginalized communities, will set the tone for managing future climate-driven extremes.
