The heat wave has started appearing in the country’s capital Delhi since the month of April. The Indian Meteorological Department (IMD) estimates that by Wednesday next week (April 15, 2026), the maximum temperature of Delhi may reach 40 degrees Celsius. Along with this, the Meteorological Department has also issued an alert of heat wave in many states. IMD said that after the recent light rain in Delhi, a continuous increase in temperature has been seen. On Saturday (April 11, 2026) too, there was bright sunshine throughout the day in the city and the maximum temperature was recorded at 34.7 degrees Celsius.
Although this temperature is currently 1.4 degrees below normal, the trend of increasing temperature is likely to continue. IMD said that by Friday (April 17) the temperature can reach 41 degrees Celsius.
Temperature continuously increasing in Delhi since last week
At the beginning of last week, the lowest maximum temperature of the decade in April in Delhi was recorded at 28.2 degrees Celsius. Since then, the temperature has been continuously increasing, which is a sign of the beginning of the summer season. According to the Meteorological Department, the maximum temperature may increase by 6–7 degrees in the next one week, due to which it will rise from below normal to above normal. At the same time, the minimum temperature, which is currently 18.6 degrees Celsius and is below average, is also expected to increase gradually. By Thursday (April 16) it can reach 23-25 degrees Celsius.
Clear sky in Delhi, but no possibility of rain soon
Experts believe that this increase in temperature is happening due to clear sky and absence of any kind of disturbance in the weather. Mahesh Palawat of Skymet Weather said, ‘Dry winds will blow in the coming days, because the effect of north-western cold winds is reducing. Due to continuous strong sunlight, no clouds and no rain, the temperature is sure to rise. He said that if the temperature goes above 40 degrees Celsius and becomes much higher than normal, then a heatwave-like situation can occur.
There may be a decline in air quality
Meteorologist Navdeep Dahiya warned that as the rain is decreasing, the temperature will gradually increase from the end of this week. From the middle to the end of next week, the maximum temperature in many cities may be recorded between 42 to 45 degrees Celsius. Delhi and Haryana may record the first 40 degree Celsius temperature of this season by 17 or 18 April.
He said that heatwave conditions may be seen in some parts of central and peninsular India. The air quality remained in the moderate category on Saturday (April 11) and is likely to remain in the moderate to poor category in the coming days.
