This Christmas Day, Brazilians across the country are preparing for wet weather as forecasters predict significant rainfall and mild temperatures amid unprecedented humidity levels. With the summer season underway, many regions are likely to experience scattered showers and thunderstorms, which may affect holiday plans for families and friends hoping to celebrate the festive season outdoors.
According to predictions from the Brazilian National Institute of Meteorology (Instituto Nacional de Meteorologia - INMET), during the week leading up to Christmas, there is a 100% chance of rain from December 23 to December 29, particularly affecting major cities such as Rio de Janeiro and São Paulo. The forecast indicates varying temperatures between 22°C and 32°C, with high humidity levels ranging from 60% to 95%.
Specifically, the city of Rio de Janeiro will see temperatures on Christmas Day (December 25) reaching up to 28°C, but could experience light rain throughout the day, with approximately 1.76mm expected. Local residents will need to keep umbrellas handy as humidity stays elevated, encouraging conditions conducive to passing showers. Such weather patterns have become increasingly common during the holiday season, compelling residents to adapt their festive traditions.
Meanwhile, Recife, known for its warm climates, isn't expecting intense sun this Christmas, as isolated morning showers give way to overcast skies later in the day. Meteorologist Patrice Oliveira from the Pernambuco Water and Climate Agency (Agência Pernambucana de Águas e Clima - Apac) emphasized on local television, “It's not the strongest sun; rather, anticipate clouds and potential fleeting showers.” Outdoor gatherings might feel the effects of humidity as residents might prefer to stay indoors to avoid sudden rainfalls.
Looking to the Central-West region, reports indicate Campo Grande may reach 30°C, but cloud cover will keep temperatures from soaring. The weather will continue to be unstable, with afternoon showers expected. Goiânia and Brasília are also forecasted to see significant rain during celebrated family gatherings. Notably, regions like West Mato Grosso do Sul could experience bursts of severe storms, especially near the Paraguayan border with wind gusts potentially reaching 50 km/h. Anyone traveling through these areas should remain vigilant.
Conversely, the southernmost state of Rio Grande do Sul has already issued warnings for intense rainfall on Christmas Eve. An impending cold front indicates particularly heavy downpours with estimates of 50mm expected overnight leading to Christmas Day, especially across the metropolitan area and other designated regions. The INMET has classified the warning as yellow, outlining necessary precautions for locals.
Indicators suggest this humidity-linked weather pattern could continue beyond Christmas, impacting New Year's Eve celebrations too. A renewed system of moisture may lead to heavy rains before and during the transition to the new year, particularly affecting coastal areas of Paraná, São Paulo, and Rio de Janeiro. Meteorologists advise caution over potential flooded areas and travel disruptions as the festive season rolls on.
Anticipation is building as families finalize plans, though many understand the necessity of being prepared for rain rather than unclouded skies to maintain the holiday spirit. Those planning outdoor festivities can still enjoy Christmas cheer under tents or awnings, as the emphasis is on family gatherings regardless of the weather.
Overall, the Christmas Day weather forecast across Brazil promises to be filled with humidity and chances of rain. It’s expected to vary geographically, urging residents to prepare for potential disruptions, but also to embrace the celebration of this holiday season with loved ones, rain or shine.
