Residents of Rio de Janeiro are sweating it out through a summer heatwave. With temperatures above 40 degrees Celsius (104 Fahreinheit), there's no option but to run to the closest shore for at night for some respite.
Hundreds of them can be seen laying on the sand of beaches like Copacabana and Ipanema -- zones usually avoided at night because of muggers but currently patrolled because of the summer vacation season.
The shore, with a slightly cooler breeze blowing in from the ocean, is the only place many of them can cool off.
Even at night, though, the mercury stays at a relatively high 30 degrees Celsius (86 degrees Fahreinheit).
