Boyle Heights, California, US – By three in the afternoon, the temperatures in this working-class Latino neighbourhood of east Los Angeles have reached nearly 37C (99F).
Patrons of a Mexican restaurant in Boyle Heights sit beneath whirring fans and street vendors selling cups of fruit recline under umbrellas, wiping the sweat off their brows. Those who leave the refuge of the shade are immediately hit with a wave of heat from the baking streets.
