Sea breezes brought lower temperatures on Friday to ease a heat wave that killed more than 1,150 people around Pakistan's teeming port city of Karachi during the Muslim fasting month of Ramadan.
Mass funerals were held for 50 unidentified victims on Friday before their bodies were hastily buried.
The extreme heat of up to 44 degrees Celsius (111 Fahrenheit) - the hottest since 1981 - coincided with power failures and triggered sharp criticism of the government's response in the city of 20 million people.
On Friday, the daily high temperature was about 36 degree Celsius (97 Fahrenheit), according to Dr Mohammad Hanif of the Director National Weather Forecasting Center.
The power outages left many without fans, water or light at the beginning of Ramadan, when many Muslims do not eat or drink during daylight hours.
"By Friday, at least 1,150 people have died in the government-run hospitals," said Anwar Kazmi of the Edhi Foundation, a private charity that runs a network of ambulances and morgues.
