Rio de Janeiro Records Hottest Day in Over a Decade at 111°F

The extreme heat has prompted citywide alerts, public health measures, and concerns as Carnival festivities approach.

Temperatures in Rio de Janeiro reached 44°C (111°F) on Monday, the highest recorded since the city implemented a climate alert system over a decade ago.
City officials issued a level four heat alert, opened hydration stations, and prepared emergency services for a rise in heat-related cases such as dehydration and sunburns.
Rio's health secretary reported over 3,000 heat-related emergency treatments in January, more than double the usual numbers seen in prior years.
Despite the heat, Mayor Eduardo Paes announced that Carnival events will proceed as planned, urging revelers to stay hydrated and take precautions.
Experts warn that this February may become one of the driest on record, with no significant rainfall expected to alleviate the intense heat.
