Kolkata is set for a dry Diwali as the Regional Meteorological Centre predicts mostly clear weather from Wednesday, 4 November, to Thursday, 5 November. Night temperatures are expected to drop to around 22°C, a fall of three to four degrees from current levels.

Cyclone Murasu’s impact on the city ended by Tuesday, 3 November, as the system weakened into a deep depression. Moisture from the cyclone had caused cloud cover and trace rain on Monday and Tuesday. Winds are shifting to dry northerly or north-westerly flow in the next two days.
However, an easterly wave could bring light rain to parts of South Bengal, including Kolkata, from the day after Diwali. On Tuesday, the city recorded a maximum temperature of 31.4°C (0.3 notches above normal) and a minimum of 26.4°C (4.2 notches above normal).
The Met office’s dry Diwali forecast removes a key worry for outdoor festivities. Residents in Kolkata can expect cooler nights dropping to around 22°C, three to four degrees below current levels. The lingering moisture from Cyclone Murasu, which only brought clouds and trace rain on 2 to 3 November, has fully passed by 3 November. Wind patterns are shifting to dry northerly or north-westerly flow in the next two days, ensuring fair weather on 4 to 5 November. However, the forecast leaves one open point: an easterly wave may bring light rain to parts of South Bengal, including Kolkata, from the day after Diwali. No heavy rain is expected.
