The mercury in the port city soared to 42°C, while the intensity of the "feels like" temperature reached 51°C at around 2pm today.
In a statement, Karachi police chief surgeon Summaiya Syed said four people lost their lives to extreme heat and humidity.
Two bodies were brought to the Civil Hospital while as many were shifted to the Jinnah Hospital, she added.

"Karachi will remain under the grip of extremely hot and humid weather for the next three days. During this period, the sea breeze will remain blocked during the day, which will increase the intensity of heat," Sarfaraz told Geo News.
Owing to the rising temperature in Karachi, the Met Office official instructed citizens to protect themselves from the heat for the next two to three days, insisting on increasing the consumption of water and juices to ensure hydration.
He added that the weather would remain hot and humid during this period, while the maximum temperature on Tuesday is likely to hover between 38°C and 40°C.

Monsoon rains may begin in the eastern parts of Sindh from July 2 or 3, while Karachi may also receive monsoon rains in the first week of July, he added.
Meanwhile, the weather in most parts of Sindh is likely to remain extremely hot for the next three days.
