As the temperature heads towards 40 degrees celsius (104 Fahrenheit) in New Delhi, Ram Babu sets off on his bicycle in an unlikely race against time to deliver ice before it melts.
The 52-year-old is one of scores of ice vendors battling traffic, potholes and hordes of people in the Indian capital to supply small shops, in a tradition spanning generations.
Weather turns: Two children die in windstorm
Babu has been buying the thick blocks from a wholesaler almost every morning for 30 years, wrapping them in brown sacks to keep them cool and then strapping them to the back of his bike.
The father of five earns about 15,000 rupees ($223) a month from selling the ice, but says income has been falling steadily as more businesses buy their own fridges. "Now obviously most households have fridges and the offices have big water coolers. It is tough to sustain profits."
Changing weather: Demand for fish rises as season begins
Affectionately dubbed the "ice man" by friends and neighbours, Babu takes pride in the tough, traditional job also done by his father and grandfather. But he said his children are more interested in finding jobs in offices and factories, and are unlikely to take over when he eventually retires. "Look, I am already 52. I will carry on working for a few more years. "But my sons are not into this. For them it is a menial job. I don't blame them and I will never force them to do it," he said.
