Winter officially begins in Brazil this Sunday (June 21), marking the end of autumn and the start of the coldest season. The astronomical event brings the shortest day and longest night of the year, characterized by a drop in temperatures and changing weather patterns across the country. According to Climatempo, the state of Rio de Janeiro will continue to experience a cold front at least through Sunday.
In Rio de Janeiro, residents have already been dealing with cold weather for several weeks. This Tuesday (June 16), the passage of a cold front combined with a high-pressure system will keep the sky cloudy and cause precipitation throughout the day. In the capital, temperatures are expected to reach a maximum of 23°C and a minimum of 19°C.
Rain is expected to persist through Thursday. According to Alerta Rio, on Wednesday (June 17) and Thursday (June 18), the weather in Rio will still be influenced by the entry of humid ocean winds. Cloud cover will vary, with light isolated rain possible at any time on Wednesday and during the early morning and morning of Thursday. Winds will be light to moderate.
By Friday (June 19), a high-pressure system will reduce cloud cover, and no rain is forecast. Winds will be moderate. On Saturday (June 20), the approach of a cold front will again influence the city's weather, with partly cloudy skies and light to moderate rain expected from the evening onward. On Sunday (June 21), the weather will remain rainy, with potential for heavy downpours in the afternoon and temperatures between 19°C and 24°C.
Why This Matters
For travelers and residents in Rio de Janeiro, this means planning for consistent rain and cold through Thursday, with a brief dry window on Friday, followed by renewed rain and possible heavy downpours over the weekend. Those with outdoor activities should adjust schedules accordingly and prepare for temperatures ranging from 19°C to 24°C.
