Delhi-NCR heatwave: 44°C forecast before monsoon arrives by June 25–30
Synopsis
Key Takeaways
Delhi-NCR is bracing for an intense heatwave on Tuesday, 9 June, with maximum temperatures forecast to touch 44 degrees Celsius even as the southwest monsoon continues its northward march across the country. Residents reported hot and humid conditions from early morning, with the India Meteorological Department (IMD) warning that relief is unlikely before mid-week.
Heatwave Conditions and Forecast
The IMD has forecast maximum temperatures in Delhi and the National Capital Region (NCR) ranging between 42°C and 44°C through 10 June, under mainly clear skies. Strong surface winds of 20–30 kmph, with gusts reaching up to 40 kmph during the day, are also expected. Similar heatwave conditions are likely to prevail over Haryana, Punjab, West Rajasthan, and parts of Uttar Pradesh through 11 June.
When Will Rain Arrive in Delhi
According to the IMD, Delhi and the NCR are likely to see spells of very light to light rainfall accompanied by thunderstorms and gusty winds of up to 60 kmph on 11 and 12 June. A fresh western disturbance is expected to affect northwest India from 11 June, bringing thunderstorms and light to moderate rainfall — offering temporary relief from the prevailing heat.
The southwest monsoon itself is forecast to reach Delhi, along with neighbouring cities such as Noida, Gurugram, and Ghaziabad, between 25 and 30 June, according to the latest monsoon progression forecast. For context, the monsoon reached Delhi on 29 June 2025 — two days later than the city's normal onset date of 27 June, based on long-term climatological data from 1961 to 2019.
Monsoon Progress Across India
The southwest monsoon, which normally sets in over Kerala around 1 June, arrived this year on 4 June — three days later than usual. Since then, it has advanced further into the Arabian Sea, Maharashtra, Karnataka, Andhra Pradesh, and Telangana. Conditions remain favourable for its further advance into Odisha, West Bengal, and the remaining northeastern states over the next two to three days.
Following its expected arrival in Delhi, the monsoon is forecast to continue northward, covering Haryana, Punjab, Chandigarh, Himachal Pradesh, Ladakh, and Jammu and Kashmir.
Heavy Rainfall Alert for Southern and Northeast India
For Tuesday, the IMD has forecast heavy to very heavy rainfall over Kerala, Karnataka, Tamil Nadu, Northeast India, and Sub-Himalayan West Bengal. Extremely heavy rainfall is likely at isolated locations in Kerala and Karnataka, while very heavy rain is expected over Assam, Meghalaya, Arunachal Pradesh, Nagaland, Manipur, Mizoram, Tripura, and Sub-Himalayan West Bengal and Sikkim.
Widespread rainfall is also likely across Konkan and Goa, Telangana, and parts of Andhra Pradesh. Authorities have warned of possible waterlogging, localised flooding, and travel disruptions in vulnerable areas. This comes amid a broader pattern of the monsoon intensifying along its leading edge while the northern plains remain under a heat dome — a split that is typical of early-June monsoon dynamics but is nonetheless straining urban infrastructure and public health systems in Delhi.
