As Delhi continues to experience soaring temperatures, touching the 40-degree Celsius mark, the India Meteorological Department (IMD) has refrained from issuing a heatwave alert for the national capital. Meanwhile, neighbouring states Gujarat and Rajasthan are expected to witness intensified heatwave conditions over the next few days.

Rising Mercury in Delhi But No Heatwave Yet

Despite the mercury reaching 40°C in Delhi, the IMD has not declared a heatwave for the region. According to the meteorological criteria, a heatwave is officially declared when temperatures reach between 42°C and 43°C. Delhi previously experienced a heatwave between April 7 and 9, 2025. Though current conditions are hot, they do not meet the technical threshold for a heatwave alert.

Forecasts for Delhi suggest that the maximum temperature will likely range from 39°C to 41°C between April 17 and April 22, with minimum temperatures hovering between 24°C and 26°C. The sky is expected to remain clear during this period, and the discomfort due to heat is likely to persist. The IMD has also indicated that temperatures may rise slightly in the coming days, with April 18 expected to record a maximum of around 41°C.

Gujarat and Rajasthan Brace for Scorching Heat

Unlike Delhi, Gujarat and Rajasthan are likely to face harsher weather conditions. The IMD has issued heatwave warnings for several parts of both states for April 17 and 18. Along with daytime heat, warm night conditions are also expected in these regions, indicating sustained high temperatures even after sunset.

The heatwave conditions are also predicted to impact parts of West Madhya Pradesh. These regions are likely to experience higher discomfort levels due to both the temperature and humidity.

Hot and Humid Conditions in Southern and Coastal States

Apart from northwestern India, southern and coastal regions including Kerala, Tamil Nadu, Puducherry, and Coastal Karnataka are expected to experience hot and humid weather. Gujarat, which falls in both western and coastal zones, will face dual effects of dry and humid heat. The rising humidity is contributing to an increase in the discomfort index, making the weather more oppressive even if the temperature does not meet heatwave criteria.

These humid conditions are expected to persist mid-week, affecting daily activities, especially for those engaged in outdoor work. The combination of temperature and moisture in the air can significantly raise the heat stress on the human body.

IMD Guidelines and Precautions

While there is no official heatwave warning for Delhi currently, the IMD continues to monitor the situation. The department advises people, especially vulnerable populations such as the elderly, children, and those with pre-existing health conditions, to take precautions. These include staying hydrated, avoiding direct exposure to the sun during peak hours, and limiting strenuous outdoor activity.

The IMD also recommends paying attention to daily forecasts and regional alerts as conditions can change rapidly. The department updates weather conditions and alerts through multiple channels including official websites, social media, and news outlets.

Conclusion

As Delhi narrowly avoids a heatwave classification despite high temperatures, states like Gujarat and Rajasthan prepare for significantly hotter days with confirmed heatwave warnings. The IMD continues to issue region-specific forecasts and encourages citizens across the country to stay informed and prepared for changing weather conditions. The rising temperatures across different parts of India underline the early onset of extreme summer conditions in 2025.
