The India Meteorological Department expects the southwest monsoon to enter India via Kerala around June 4, 2026 [1].
The arrival of the monsoon is critical for India's agricultural sector and water security, as the seasonal rains provide the primary source of water for crops and reservoirs across the subcontinent.
Weather officials have placed Mumbai under a yellow alert [1]. While some reports indicate rains will arrive in the city around June 5, 2026 [5], other forecasts place the arrival generally within the first week of June [1].
In the north, the IMD has forecast thunderstorms for Delhi [1]. These weather patterns coincide with the broader seasonal shift as the monsoon winds move inland from the coast.
There are conflicting reports regarding the exact timing of the monsoon's onset in the south. Some early projections suggested the southwest monsoon was likely to set in over Kerala as early as May 26, 2026 [4]. However, more recent data from the IMD and other reporting agencies point toward a June 4 entry date [1].
Local authorities in Mumbai and Delhi are monitoring the situation as the yellow alert indicates a need for caution regarding potential thunderstorms, and heavy rainfall [1]. The IMD continues to track the movement of the monsoon system to provide updated arrival windows for various states.
“The India Meteorological Department expects the southwest monsoon to enter India via Kerala around June 4, 2026.”
The variance in onset dates, ranging from late May to early June, highlights the volatility of monsoon tracking. Because the Indian economy is heavily dependent on the timely arrival of these rains for agriculture, any delay or unexpected intensity in the initial phase can impact food prices and water management strategies for the year.
