Heat Wilting Rio Carnival Street Parties

The hottest temperatures in five decades were melting Carnival revelry Tuesday after five days of dancing, drinking and smooching.

"I never thought I would say this, but it is too hot to party," said 20-year-old Thiago Cerveny, standing on a corner with his girlfriend in Ipanema and debating whether to hit a big street party on the last full day of festivities.

Rio's summer has seen record highs of up to 110 F (44 C). Couple that with the seaside city's suffocating humidity and the chances that partiers will fall ill increases.

It was 106 F (41 C) Tuesday.

Dr. Luis Fernando Correa took to the Globo television network to warn those still partying to "drink a lot - but nothing alcoholic."

Taking the booze out of what Brazilians call the world's biggest bash is certainly a challenge. Health officials say more than 1,400 revelers have been treated since Saturday, the majority for heat-related illness.

"During Carnival people go out in the street, they party, they forget to hydrate and even take medications they may need," Correa said. "People, drink water!"

The withering temperatures punished participants in Rio's Carnival parades Monday night, many wearing heavy, elaborate costumes.

Geisy Arruda, a 20-year-old student who gained fame when she was expelled in October from her school for wearing a miniskirt, succumbed to the heat toward the end of her 80-minute appearance on a parade float.

She was seen tugging at her Carnival dress - a flashy version of the garment that got her thrown out of school - and had to lie down on a and ask for water. She rested and recovered.

The weather was decidedly cooler in New Orleans, where the final day of Carnival was sunny and cold with high temperatures expected to hang around 50 degrees Fahrenheit.

Cold Temps Don't Faze Mardi Gras Revelers

Back in Rio, other Carnival queens, some with massive headdresses and elaborate wings of feathers harnessed to their backs, slumped down atop massive floats and asked people 30 feet below to throw them bottles of water.

But the heat didn't stop the majority of the exceptionally trained samba dancers, whose moves and athleticism rival this nation's famed football stars.

Funk dancer and Playboy model Valeska Santos wore a pedometer, and according to the O Globo newspaper she walked 7.5 miles (12 kilometers) during her 80 minutes in the parade early early Tuesday - all the while doing a frenetic samba and wearing a massive feather costume.

Though she had been in the hospital with pneumonia for 15 days just before Carnival, Santos wasn't done though: She also danced atop another group's samba float a few hours later.

This year's Carnival was the first since Rio was awarded the 2016 Olympics. Security was good for the most part, but police say about 50 tourists were robbed.
