Belo Horizonte and Rio Record Sharp Cold Lows as Cities Send Alerts

Overview

• Belo Horizonte registered the lowest temperature of the year at 8.8°C in the Pampulha area early Saturday, marking successive daily minima through the first week of June.
• Rio de Janeiro logged its coldest night of 2026 on Saturday with Inmet reporting 12.5°C at Vila Militar and the Alerta Rio network recording 11.3°C at Alto da Boa Vista.
• The Defesa Civil of Belo Horizonte issued a 'severe' cold-wave alert and sent automatic cell‑broadcast and SMS warnings saying morning lows could fall below 10°C.
• The National Institute of Meteorology has active advisories elsewhere in the country that warn of low humidity in parts of the Center‑West and Southeast and heavy accumulated rain and storm risk in sections of the North and Northeast.
• Meteorologists attribute the episode to a polar air mass plus strong nocturnal radiative cooling, which favors very low urban minima and frost risk in highlands, and they say the cold should ease with a slow warming trend from around June 10.
