Rainy Weekend For Bengaluru; Heavy Showers Likely Today
Key Takeaways:
- Bengaluru has remained dry for the last five days despite the ongoing pre-monsoon season.
- Good rain and thundershowers are likely over Bengaluru and nearby suburbs during the weekend.
- Weather activity is expected to peak during late afternoon and evening hours.
- Day temperatures around 35°C may dip slightly due to increasing rain activity.
The capital city, Bengaluru, has remained completely dry for the last five days. As such, the city has received minimal rainfall during May so far. The city observatory and HAL station have recorded 31 mm and 8.2 mm rainfall, respectively, between May 1 and May 15, 2026. The month has a normal rainfall of 110.4 mm. Good showers are likely over the city and suburbs during the weekend.
The well-marked low-pressure area over the Southwest Bay of Bengal will move northeast and weaken as well. It will loosen its grip on the wind flow over the South Peninsula. The seasonal north-south pre-monsoon trough over the interiors of the Peninsula will get back to its normal position. It is extending from South Chhattisgarh to the Comorin region across Telangana, Karnataka, Rayalaseema and the border areas of Tamil Nadu and Kerala. The trough will oscillate east-west to expand the area of weather activity.
Bengaluru has the advantage of sitting on a plateau with an elevation of about 3,000 feet. This provides an additional trigger for the pre-monsoon weather activity around the area. The city and suburbs are likely to receive fairly widespread rain and thundershowers, more pronounced during the next three days. The weather activity will peak around the late afternoon, evening and early night hours. Light and sporadic showers are likely at the start of next week as well. The spread and intensity of rainfall will be uneven across different sectors of the city. The day temperature, hovering around 35°C for the last five days, is likely to dip by a couple of notches. Broad clearance in the weather activity is expected after May 20, 2026.
