The Servicio Meteorológico Nacional (SMN) forecasts a weekend of pleasant temperatures and partly cloudy skies in the City of Buenos Aires (CABA). Light showers fell Saturday evening as predicted. Simultaneously, five provinces are under alert for storms tonight.
Weekend Weather Outlook
The SMN anticipated Saturday would be partly to mostly cloudy in the metropolitan region, with temperatures ranging from 13 to 23 degrees Celsius. Rain arrived in CABA Saturday evening, with these light precipitations potentially extending to the rest of the AMBA overnight.
Sunday will see a slight temperature increase, with highs between 16 and 25 degrees Celsius. A slight chance of precipitation exists early Sunday, but the rest of the day will remain partly cloudy with no instability.
Looking Ahead to Next Week
The coming week will begin with stable conditions in the AMBA. Monday will be partly cloudy with temperatures between 17°C and 24°C. Tuesday will be similar, with a low probability of rain later in the day. Wednesday will continue the trend with similar temperatures and a low chance of precipitation.
Thursday is expected to see a slight drop in the low temperature to around 16°C, with a high of 24°C and mostly cloudy skies. Friday will close out the week with rising temperatures, between 18° and 25°, and fewer clouds.
Storm Alerts and Seasonal Trends
Storm alerts are currently in effect for Córdoba, Chaco, Formosa, Misiones, and Corrientes. Affected areas can expect “abundant precipitation in short periods, intense electrical activity, occasional hail, and gusts.” Accumulated rainfall is estimated between 30 and 70 millimeters, according to the SMN.
Four provinces in the Northeast will continue to face forecasts of heavy rain on Sunday. The SMN has issued a yellow alert for Misiones, the north, northwest, and northeast of Corrientes, eastern Chaco, and central Formosa. An orange alert is in effect for eastern Formosa, where the storms are expected to be particularly intense.
¿El calor fuera de lo habitual seguirá durante todo el otoño?
The SMN recently released its new seasonal forecast for Argentina, covering the April-June 2026 period. The forecast indicates that temperatures above normal will persist throughout much of the country this autumn. The climatic scenario anticipates that the atypical heat that marked the end of March will continue in the coming weeks, affecting both the center and north of the national territory.
The institution’s report shows a pronounced trend toward elevated temperatures, especially over Buenos Aires, Córdoba, Santa Fe, the Litoral, and northeast San Luis. The forecast, based on global simulation models and national statistical data, indicates a 45% probability that temperatures will be above historical averages in those regions.
The autumn season is also expected to see higher-than-normal precipitation volumes in large sectors of the north and central parts of the country. According to the institution, “the probabilities of rainfall above normal reach the NOA (Northwest), Córdoba, western Santa Fe, eastern San Luis, and central-eastern Buenos Aires.”
This combination of exceptional temperatures and humidity was reflected in the last week of March, when the Metropolitan Area of Buenos Aires experienced peaks of over 31°C and thermal sensations exceeding 37°C. These records are due to an atmospheric block that prevented significant climate variations.
