IMD forecasts rain and thunderstorms in Delhi-NCR from June 18–21
Synopsis
Delhi-NCR is set for a week of intermittent rain and thundershowers from June 18–21, with the IMD keeping temperatures capped below 40°C. Western disturbances and local weather systems are doing the heavy lifting — but humidity may linger even as the heat eases.
Key Takeaways
The IMD has forecast intermittent rain and thunderstorms across Delhi-NCR from 18 June to 21 June 2025 .
Maximum temperatures are expected to remain below 40°C throughout the period; no weather warnings or alerts have been issued.
Temperatures on 20 June are forecast to dip to a weekly low of 37°C maximum and 29°C minimum.
Conditions from 22–23 June are expected to be relatively stable, with partly cloudy skies and maximums of 38–39°C .
Western disturbances combined with local weather systems are credited with suppressing heat and triggering rainfall.
Humid conditions may persist in parts of the NCR even as temperatures moderate.
The India Meteorological Department (IMD) has forecast intermittent rain, thundershowers, and strong winds across Delhi-NCR from 18 June to 21 June 2025, offering residents a reprieve from the region's prevailing heat. Crucially, the IMD has not issued any weather warnings or alerts for the period, and maximum temperatures are expected to remain below the 40-degree Celsius threshold throughout the week.
Day-by-Day Temperature Forecast
On 18 June, the maximum temperature is pegged at 38°C with a minimum of 26°C. The mercury is expected to nudge up slightly on 19 June, reaching 39°C during the day and settling at 28°C overnight. By 20 June, a dip is anticipated — the maximum is forecast at 37°C and the minimum at 29°C. On 21 June, the maximum is likely to be around 38°C, with the minimum touching 30°C.
What Is Driving the Weather Change
According to meteorologists, the combined influence of western disturbances and local weather systems is suppressing temperatures and triggering intermittent precipitation. This pattern is consistent with the pre-monsoon transition phase that typically affects northern India in mid-June, when moisture-laden winds begin interacting with dry continental air over the Indo-Gangetic plain. Strong surface winds accompanying the thundershowers are expected to further moderate the heat index.
Conditions After June 21
The IMD forecast indicates relatively stable conditions on 22 June and 23 June, with partly cloudy skies persisting across the NCR. On 22 June, the maximum and minimum temperatures are expected at 38°C and 31°C respectively. On 23 June, the maximum could climb to 39°C while the minimum is likely to hold around 31°C. Notably, while heatwave-like conditions appear unlikely, humid weather may persist in pockets of the region even as temperatures stay within the normal range.
Impact on Residents
The forecast provides meaningful relief for Delhi-NCR's residents, who have endured above-normal heat in the weeks leading up to this period. Cloud cover and gusty winds are expected to keep conditions relatively comfortable. However, the IMD's guidance that humidity may linger in some areas suggests that the perceived discomfort could remain elevated even as raw temperature readings moderate. Outdoor workers and commuters are advised to stay updated on localised conditions, as thunderstorm activity can be uneven across the wide NCR geography.
Point of View
But the absence of any weather alert should not breed complacency — thunderstorm activity in the NCR can intensify rapidly, and the department's own data shows that localised squalls have caused infrastructure damage even in 'no-alert' windows. The more significant signal here is that temperatures are being held below 40°C by a confluence of western disturbances and pre-monsoon moisture, suggesting the monsoon's northward advance may be on track. If that advance stalls, as it has in several recent years, this relief window could be brief and the heat could return sharply after June 23.
