Bengaluru Heatwave 2026: Alert, Temperature Rise & Safety Tips ☀️

Summer 2026 has brought unusually high temperatures in many parts of Karnataka, especially Bengaluru and surrounding districts.

Many residents are searching:

• Why is Bengaluru so hot this year?

• What is the temperature today?

• Is there a heatwave alert?

• How can we protect our family?

In this blog, we explain everything in simple language for Karnataka residents.

What Is Happening in Bengaluru This Summer?

According to updates from the
India Meteorological Department (IMD), Karnataka is experiencing higher-than-normal temperatures in several districts.

Bengaluru, which was once known for its pleasant climate, is now touching temperatures above 35–38°C in some areas.

Though this may look normal compared to North India, for Bengaluru residents this feels extreme.

Why Is Bengaluru Getting Hotter?

There are several reasons:

1️⃣ Climate Change

Climate patterns are changing globally.

Irregular rainfall and increasing temperatures are affecting Karnataka too.

2️⃣ Urbanization

Bengaluru has seen rapid growth:

• More buildings

• Fewer trees

• More vehicles

Concrete absorbs heat and increases local temperature. This is called the “urban heat island effect.”

3️⃣ Reduced Green Cover

Earlier, Bengaluru was called the “Garden City.”

But due to development, tree cover has reduced in many areas.

Less greenery means less natural cooling.

What Is a Heatwave?

A heatwave is declared when temperature rises significantly above normal levels for consecutive days.

IMD issues:

• Yellow alert (be cautious)

• Orange alert (be prepared)

• Red alert (take action)

Residents should follow official weather updates regularly.

Which Areas in Karnataka Are Most Affected?

Apart from Bengaluru, districts like:

• Kalaburagi

• Raichur

• Ballari

• Vijayapura

often experience very high temperatures during peak summer.

North Karnataka usually faces more severe heat compared to southern districts.
