"Brazil has officially marked the beginning of summer, with meteorologists warning of a season that is expected to be significantly warmer than the historical average. This phenomenon is directly linked to climate change, according to experts. Footage filmed on Sunday shows locals and tourists enjoying Ipanema Beach in Rio de Janeiro and its amenities. For many workers in the tourism industry, the arrival of visitors during the summer is a significant economic opportunity, particularly during periods of intense heat, which attracts people seeking sun and beaches. "For us, it is great to come here and know that summer is arriving with this intensity; it is always better," said Robson Neto, a vendor. According to the National Institute of Meteorology (INMET), temperatures could exceed 40°C across the country due to its location in the southern hemisphere, which means it receives more solar radiation at certain times of the year, especially during summer (December), resulting in longer days than nights. Among young people, the arrival of summer is also associated with more outdoor activities and social gatherings. However, the combination of high temperatures and humidity has prompted health warnings about heatstroke and dehydration, especially during peak hours of sunlight. "Whether you like it or not, it is the beach. You have to have a drink and enjoy some time at the beach, cool off and stay hydrated as well," said Gilvan Yaris, a vendor. Although the summer season in Brazil is positive for economic activity and tourism, it also brings challenges for public health, energy infrastructure, and daily life due to the high humidity. Hospitals often see an increase in heat-related illnesses, and the increased demand for air conditioning leads to critical electricity consumption levels. Local authorities recommend taking precautions against extreme heat, including staying hydrated and avoiding direct exposure to the sun during the hottest hours of the day."
