The metropolitan area will experience a weekend with stable thermal marks, although weather models already anticipate a new wave of extreme heat for the first days of February.
The weather scenario for the Buenos Aires Metropolitan Area (AMBA) presents a brief thermal respite that will act as a prelude to a phenomenon of extreme heat.
According to the latest data from the SMN, the forecast in the AMBA indicates that, after a period of relative relief thanks to the east sector winds, the atmosphere will begin to prepare for a marked rise in thermometers that could lead to the third heat wave of the year 2026.
During this weekend, conditions are expected to remain within moderate parameters for the summer season.
The predominant wind from the Río de la Plata will continue to act as a natural regulator, preventing maximums from exceeding 30°C in the Autonomous City of Buenos Aires and the northern belt of the suburbs.
However, in localities towards the west and south, values could be slightly higher due to the lesser influence of the river breeze.
The transition to extreme heat
The stability of Saturday and Sunday will function as a transition phase. Specialists warn that the atmospheric configuration will change drastically with the start of the new month.
The displacement of a high pressure system will favor the arrival of warm air masses from the north, which will push the mercury above 33°C in a sustained manner.
For a new extreme heat wave to be officially declared, the region must record at least three consecutive days with minimum temperatures above 22°C and maximums exceeding 32.3°C.
Forecast models suggest that these conditions could consolidate from the first week of February, affecting not only the AMBA but also a large part of the central area of the country.
Recommendations and monitoring
In light of the possibility of this thermal event, it is recommended that the population stay informed about alerts issued by the National Meteorological Service.
The impact of these high temperatures is usually persistent, making it difficult for homes to cool down at night and increasing the risk of water stress and heat strokes in vulnerable groups.
