Heavy Rainfall to Persist Across Maharashtra and Karnataka Amid Pre-Monsoon Surge
May 28, 2025, 5:48 PM | Skymet Weather Team
May has brought intense and widespread pre-monsoon rains to Maharashtra and Karnataka, making it one of the wettest in recent memory. Although the southwest monsoon officially arrived in most parts of Karnataka and many parts of Maharashtra on May 26—well ahead of schedule—the bulk of the rain so far is considered pre-monsoon activity, as the official monsoon season begins on June 1.
This year has already set a record for the earliest monsoon onset in Mumbai. Between May 1 and May 27, rainfall across several regions has been exceptionally high.
Konkan and Goa reported a staggering surplus of 2277%, while Madhya Maharashtra was up by 500%, Marathwada by 335%, and Vidarbha by 421%. Karnataka too has seen large excesses—Coastal Karnataka by 392%, North Interior Karnataka by 209%, and South Interior Karnataka by 105%.
A cyclonic circulation hovering over the eastern central Arabian Sea, near the Karnataka coast, is fuelling these intense rain systems. Over the next 48 hours, moderate to heavy rainfall, with isolated very heavy spells, is likely to continue in the Konkan and Goa regions. Southern parts of the Konkan coast—including Alibag, Raigarh, Sindhudurg, and Ratnagiri—along with Goa, are expected to receive significant rainfall.
In contrast, northern Konkan cities like Mumbai, Thane, and Dahanu may see only light to moderate showers, providing a brief respite for the commercial capital from the recent deluge.
Interior regions of Maharashtra—including parts of Vidarbha, South Madhya Maharashtra, and Marathwada—are also expected to witness heavy rainfall within the next 24 hours.
Meanwhile, heavy rains are set to persist over Karnataka's coastal belt, including districts like Belagavi, Mangaluru, Dakshina Kannada, Uttara Kannada, and Honnavar, for the next 3–4 days.
With the monsoon likely to advance further into more regions of Maharashtra and cover all of Karnataka over the next 48 hours, residents should stay alert for continued wet weather and potential disruptions.
