Bengaluru: Bengaluru has witnessed a record 307.9 mm of rainfall in May due to the intensity of pre-monsoon and monsoon showers.
Due to a low-pressure area in the Arabian Sea, both pre-monsoon and now monsoon rains have brought continuous downpours to Bengaluru over the past 10 days. In particular, the heavy rainfall on May 18–19 disrupted normal life in the city. The rain has continued since then, resulting in this May recording the highest rainfall compared to previous years.
Previously, the highest rainfall recorded in May was 305.4 mm in 2023. Before that, 270.2 mm was recorded in 2022. In other years, May rainfall did not cross the 250 mm mark. From May 1 to May 26 this year, a total of 307.9 mm of rainfall has been recorded. With five days remaining in the month, rainfall could increase further.
