The climate continues to be marked by intense heat and unstable weather in the last few days before the turn to 2026. According to meteorologists, the presence of a strong atmospheric blockage has kept temperatures high in the region, while the combination of humidity and clouds brings the chance of isolated rain showers, with thunderstorms and even the possibility of hail in parts of the city.
On Tuesday (30/12), the forecast indicates many clouds throughout the day, with the potential for rain showers from the afternoon onwards, especially in areas further away from the urban center. Temperatures vary between 20 °C e 33 °Cmaintaining the feeling of humid heat typical of Rio’s summer. There is a possibility of isolated electrical discharges associated with precipitation.

The last day of the year (12/31) should not bring significant changes in the weather pattern. Instability persists, and the forecast again includes heavy clouds, with rain and thunderstorms. Meteorologists emphasize that there is a chance of hail in specific areas, a rare phenomenon in the capital, but not ruled out given the atmospheric conditions observed. Temperatures predicted for the day vary between 21 °C and 34 °C.
The combination of high heat and humidity favors short-term rain showers, often concentrated in the late afternoon or early evening. This pattern is common in Rio’s summer, especially when the maritime circulation is weak, allowing the formation of convective clouds throughout the day.
For those who intend to take to the streets in the coming days, whether for last-minute shopping, end-of-year celebrations or outings, it is recommended to keep an eye on the forecast before planning outdoor activities and consider shelter options in case of heavy rain or thunderstorms.
