Bengaluru Weather Swing 2026: Temp Drops 5°C as Coast Hits 37°C

The residents of Silicon City have been on a bizarre weather seesaw. Though the week opened with scorching afternoon temperatures, the last 48 hours have seen unprecedented changes in the month’s weather in the city. By mid-February 2026, data suggested, Bengaluru’s maximum temperature dropped from a boiling 32°C on Tuesday to a cool 27°C by Wednesday - a staggering loss of 5°C in 24 hours.

This sudden "cool spell" has caused the population to alternately switch between light summer-in-the-afternoons light clothing and soft woolens during the chilly nights.

Bengaluru’s Day-Night Paradox

The capital is experiencing “classic swing” in the present. 

• The Chill Factor: Early mornings and late nights remain surprisingly cool, with minimum temperatures varying between 14°C and 16°C.
• The Afternoon Surprise: Despite being bright sun, the "feel-like" temperature has plummeted due to the dry northerly winds.
• Health: Those 15-degree temperature swings between day and night (14°C and 29°C) are fertile ground for viral infections, common colds and seasonal allergies as warned by health experts.

Coastal Karnataka: A Different Kind of Hotness

While Bengaluru enjoys a temporary lull from the severe heat, the story is very different along the coastline of Karnataka. There is a localised heat wave, with several districts in the region seeing temperatures much higher than the typical norm. Key Temperature Highlights:

• Karwar: The state's highest temperature is 37°C or scorching dry heat.
• Honnavar: Followed closely at 36.1°C.
• Mangaluru: With the port city now in the grip of 34°C and high humidity, perceived temperature still doesn't seem low.

The India Meteorological Department (IMD) says this dry heat is now reaching into North Karnataka. Districts like Kalaburagi and Koppal have also hit 34°C, indicating early summer is afoot for interior regions.

What’s Causing the Swing?

Meteorologists attribute Bengaluru's abrupt cooling to an upper air cyclonic circulation over the Equatorial Indian Ocean, which is changing the wind patterns across South Interior Karnataka. In the meantime, the coastal belt is facing a dearth of sea breeze combined with blowing hot winds from neighbouring areas.

Coastal and northern belt people need to remain hydrated and prevent direct sun exposure between 12:00 PM – 3:00 PM, and those living in Bengaluru should wear sweaters when the nights are surprisingly cool to avoid the excessive perspiration.
