If it's 40°C in Delhi, why does it feel like 50? IMD reveals the cause, and predicts more hot days ahead

The national capital, Delhi, recorded a high temperature of 41.8°C on Tuesday, but it felt much hotter because of the humidity. The India Meteorological Department (IMD) said the humidity level was between 67% and 43%, making it very uncomfortable for people outside.

Humidity makes the air feel hotter than it really is. Even if the thermometer shows 40°C, the actual ‘felt’ temperature can be 3 to 5 degrees higher, or more. On Tuesday evening, Safdarjung station recorded 40°C, but because of the 43% humidity, it felt like nearly 50°C.

On Monday, humidity was even worse, going up to 74%, which is very high for Delhi in May, according to the IMD.

The IMD explained that the reason for this sultry weather is the frequent western disturbances causing rain and thunderstorms. Also, a major cyclonic system over the Arabian Sea is sending more moisture into Delhi, adding to the humidity.

Though some rain is expected, it will only bring temporary relief. The IMD has forecast rain and thunderstorms on Wednesday, with maximum and minimum temperatures likely around 39°C and 29°C.

Since the monsoon usually arrives in Delhi only by late June, residents will likely face this uncomfortable, sticky weather for a few more weeks.
