The India Meteorological Department (IMD) has forecast light to moderate rainfall over the next several days. A yellow alert has been issued for isolated spells of heavy rain in parts of the state, between May 12 and May 16.
Thunderstorms accompanied by lightning and gusty winds are predicted across interior Karnataka during this period. South Interior Karnataka, including Bengaluru, is expected to receive heavy showers, from May 12 to 16. Northern districts are likely to experience similar conditions on May 13 and 14, according to the IMD.
The IMD has predicted rainfall across Karnataka over the next seven days , with varying intensity across regions. On May 14, heavy rains with winds (50–60 kmph) are likely in parts of Udupi, Dakshina Kannada, Belagavi, Dharwad, and Ballari, while most other districts can expect light to moderate showers.
From May 15 to 16, widespread light to moderate rain is likely across coastal, north interior, and south interior Karnataka, including districts like Bengaluru, Chikkamagaluru, Hassan, and Vijayapura. The trend is expected to continue through May 17 to 20, with consistent light to moderate rainfall forecast across most districts. Coastal areas such as Dakshina Kannada, Udupi, and Uttara Kannada will continue to see steady rainfall, while interior regions like Kalaburgi, Raichur, Mysuru, and Tumkur will also receive precipitation.
The heaviest downpours are likely in the ghat sections and coastal districts like Dakshina Kannada, Udupi and Uttara Kannada. Drought-prone districts such as Vijayapura and Bagalkote are forecast to receive normal rainfall.
Meanwhile, speaking to TNM, IMD scientist GS Patil said that this summer has so far been normal when compared to 2024, with no reported heatwave conditions or threats to water availability.
According to him, the state is expected to receive normal rainfall overall, with the Southwest Monsoon likely to set in by the first week of June, close to the usual date of June 5.
“South Interior Karnataka can expect normal rainfall,” he said adding, “but we are expecting above-normal rainfall in North Interior Karnataka and along the coast.”
Patil said Karnataka’s overall weather indicators are stable, with temperatures remaining within the seasonal range and the southwest monsoon expected to arrive around its usual date, June 5.
Unlike last year, when heatwaves and dwindling reservoirs strained communities across the state, this year’s rainfall patterns suggest a steadier water outlook, he predicted.
