Delhi Weather Alert: 6 Shocking Forecast Updates as Temperature Hits 39°C & AQI Turns ‘Poor’

Delhi is experiencing an early surge in summer heat, with the temperature peaking at 39°C on April 4—five degrees above the seasonal average—marking the hottest day of the year so far. The India Meteorological Department (IMD) expects the mercury to rise further in the coming days, potentially crossing the 40°C mark, though no heatwave warning has been issued yet. Skies are expected to remain clear, accompanied by strong surface winds that will intensify the heat. The capital’s air quality also remains a concern, with the AQI hovering in the ‘poor’ category, recorded at 215 on Friday morning.

The Delhi government is planning a trial for artificial rain in May to combat rising pollution levels, with assistance from IIT Kanpur and DGCA. Meanwhile, southern cities like Bengaluru and Chennai are forecasted to receive light rainfall throughout the week, offering some respite from the heat. In contrast to Delhi’s dry spell, Bengaluru will see cloudy skies and scattered showers, while Chennai expects light rain turning into steady showers. The overall weather trend signals a hot and challenging start to summer for Delhi, with little relief in sight for now.

Delhi Weather Alert: 6 Shocking Forecast Updates as Temperature Hits 39°C & AQI Turns ‘Poor’

Delhi has officially entered its summer season, recording its hottest day so far with temperatures hitting 39°C on Friday—five degrees above the seasonal average, as reported by the India Meteorological Department (IMD). This surpasses the previous high of 38.9°C on March 26. With the mercury expected to breach the 40°C mark in the coming days, residents are preparing for a relentless heatwave.

Rising Temperatures and Weather Outlook

The IMD warns that Delhi’s daytime temperatures will continue climbing, with forecasts predicting highs of 40–41°C between April 6 and 8. Strong surface winds (20–30 km/h, gusting up to 40 km/h) will add to the discomfort, making the heat feel even more intense. While mornings remain relatively cooler (minimum temperatures around 16–22°C), the afternoons are turning increasingly harsh. Skies will stay clear, offering no respite from the sun.

Air Quality Concerns

Delhi’s air pollution remains a pressing issue. On Friday, the Air Quality Index (AQI) hovered at 215, falling into the ‘poor’ category, as per the Central Pollution Control Board (CPCB). To combat this, the Delhi government plans to trial artificial rain in May. Environment Minister Manjinder Singh Sirsa announced a pilot project, coordinated with IIT Kanpur and aviation authorities, to test cloud-seeding technology in an outer district of the capital.

Heatwave Criteria and Current Conditions

While Thursday saw temperatures reach 37°C—slightly above IMD’s forecast—the city is not yet in a heatwave. The IMD defines a heatwave as temperatures hitting 40°C or staying five degrees above normal for two consecutive days. Officials confirm no immediate heatwave alerts but urge caution as the heat intensifies.

Southern Cities Get Rain Relief

In contrast to Delhi’s scorching weather, southern cities like Bengaluru and Chennai are expecting rain. Bengaluru will see cloudy skies with intermittent thundershowers (21–31°C), while Chennai anticipates light rain throughout the week (26–35°C). These showers are likely to bring temporary relief from the summer heat.

Weekly Forecast for Key Cities

Delhi (April 4–9):

• Temperatures will rise steadily, peaking at 41°C by April 7–8.

• Nights will warm slightly, from 19°C to 22°C, but days remain blistering.

Bengaluru (April 4–9):

• Cloudy skies with rain or thundershowers expected until April 7.

• Daytime highs near 30–31°C, offering cooler conditions.

Chennai (April 4–9):

• Light rain persists, with heavier showers expected by April 8–9.

• Humidity and highs around 33–35°C will dominate.

Health and Safety Advisory

With AQI levels in the ‘poor’ range, residents—especially those with respiratory issues—are advised to limit outdoor activities. The IMD recommends staying hydrated, avoiding direct sun exposure during peak hours (11 AM–4 PM), and using protective gear like hats and sunscreen.

Looking Ahead

Delhi’s summer is set to intensify, with no immediate relief in sight. The artificial rain initiative highlights efforts to tackle pollution, but its success remains to be seen. Meanwhile, southern India’s rain patterns underscore the country’s diverse climate dynamics. As temperatures climb, authorities stress preparedness to mitigate health risks and infrastructure strain during the sweltering months ahead.
