What Is Causing the Sudden Dip in Bengaluru’s Temperatures?

Published: Monday, January 20, 2025, 9:49 [IST]

Bengaluru witnessed its first significant rainfall of the season, bringing a refreshing chill to the city. Morning temperatures dipped to 21.4°C, a remarkable 7.1°C below average, offering a cool and cozy start to the day. The rainfall, more than just a drizzle, delighted residents accustomed to warmer weather, transforming the city's atmosphere.

What Caused the Rain?

The India Meteorological Department (IMD) attributes the rain to a weakening trough in the easterlies over the Southwest Bay of Bengal, near Tamil Nadu. The event is also linked to a developing cyclone near Sri Lanka, affecting weather patterns across Karnataka, including Bengaluru.

Cool Week Ahead for Bengaluru

The city is set to experience:

Partly Cloudy Skies with light rain in some areas.
Temperatures ranging from 16°C to 26°C, ensuring comfortable weather.
Morning Fog or Mist, adding a serene touch to the week ahead.

Impact on Karnataka

While Bengaluru enjoys the cool spell, other districts in Karnataka face varied weather conditions:

Light rains expected in Dakshina Kannada by Monday.
Interior and Coastal Karnataka to remain mostly dry.
Severe cold wave alert for Bidar, Kalaburagi, and Raichur, with temperatures plunging below normal.

Bigger Picture: La Niña's Influence

Global weather patterns are also playing a role. La Niña, confirmed by NOAA's Climate Prediction Center, is causing cooler-than-average sea surface temperatures in the Pacific Ocean. This phenomenon is influencing weather across the globe and contributing to Bengaluru's refreshing change.

For Bengaluru's residents, the rainfall and cool temperatures are a delightful surprise. The IMD's forecast suggests a continuation of this pleasant weather, marking a refreshing start to the season.

As Bengaluru embraces this unexpected weather shift, the city is set for a week of cool, serene days-an ideal backdrop for enjoying the charm of the Garden City.
