IMD Forecast: Mumbai To Receive 106% Above-Normal Rainfall In July 2025

The India Meteorological Department (IMD) has projected that Mumbai will receive 106% above the Long Period Average (LPA) rainfall for July 2025, indicating a significantly wetter month than usual for the city.

Weather Alerts in Place

The IMD has issued weather alerts across Mumbai and neighboring districts:

Yellow Alert has been issued for Mumbai, Thane, and Palghar districts, warning of heavy rainfall at isolated locations through Thursday. Additional yellow alerts are in effect for the upcoming weekend (July 6-7).

Orange Alert has been declared for Raigad and Ratnagiri, forecasting heavy to very heavy rainfall between Thursday and Sunday.

Rainfall Pattern and Forecast

Mumbai witnessed intermittent moderate showers on Wednesday, with IMD issuing nowcast warnings for intense rain spells during the day.

Heavy rainfall is expected in isolated pockets on Thursday, followed by a brief reduction in intensity on Friday.

The rain is forecast to intensify again starting July 6, continuing into the weekend.

July is Mumbai's wettest month, and IMD predicts this year's totals will exceed the seasonal average, with Santacruz and Colaba observatories already reporting substantial rainfall since May.

Meteorological Drivers

The surge in rainfall is linked to a low-pressure system over Jharkhand and eastern Madhya Pradesh, which, along with a monsoon surge, is drawing moisture into the Konkan region.

Additionally, another low-pressure area is expected to form and track westward, likely enhancing rainfall in Mumbai and surrounding districts over the weekend.

IMD's Broader Outlook

According to IMD's extended forecast, above-normal rainfall is expected across several parts of India through the month of July.

The early arrival of the monsoon, which covered the entire country nine days ahead of schedule, has played a role in the robust rainfall activity seen in western India, particularly Mumbai.

Advisory for Residents

Residents are urged to monitor IMD updates regularly and to exercise caution during heavy rainfall, especially in regions currently under yellow and orange alerts.
