Temperatures falling to 7°C in parts of the Buenos Aires suburbs highlight a sharp shift from mid-week warmth as a cold front moves across the region.
Cold Front and Pampero Winds Bring Temperature Drop to Buenos Aires
After a mostly clear Thursday with mild conditions, the arrival of a cold front is setting up a weekend with readings typical of another season during the early hours, according to the available forecasts.
The cooling will hit the Buenos Aires suburbs hardest, with Sunday morning minimums expected to range between 7 and 9°C. Ahead of that chill, Saturday brings gusts reaching up to 60 km/h and high temperatures staying below 20°C, before a thermal recovery begins with sunny days and high daily temperature ranges.
Did You Know? The Pampero, a southwest wind, blows through the region with gusts reaching up to 40 km/h to clear out clouds and close out the first unstable episode of the week.
Mid-Week Stability Precedes Weekend Chill
Wednesday afternoon wraps up with temperatures between 23 and 24°C after a spell of scattered showers and thunderstorms with irregular distribution. Clear skies overnight allow readings to drop to 13°C in the city of Buenos Aires and 10°C in the suburbs by Thursday dawn.
Thursday shapes up as the best work week day with mostly clear skies and a high of 25°C in the metropolitan region. That stability remains temporary, however, as cloud cover increases on Friday afternoon ahead of a cold front advancing from Patagonia.
Friday features highs between 23 and 25°C before rain chances climb to 90% by evening, though expected rainfall totals remain low in millimeters. Behind this system, winds shift to the south with gusts exceeding 40 km/h.
Weekend Winds and Sub-20°C Highs
Saturday opens with gray skies and possible drizzle across western and southern sectors of the metropolitan area. Cloud cover decreases toward the afternoon, but temperatures stay low with highs between 18 and 19°C alongside south wind gusts ranging from 45 to 60 km/h.
Forecasters advise monitoring the behavior of the Río de la Plata along low-lying riverside areas during these strong winds. Sunday morning brings the coldest readings of the period, featuring 10 to 11°C in the city and 7 to 9°C in Greater Buenos Aires, where the northern suburbs register the lowest values.
Daytime sunshine lifts Sunday highs to between 21 and 23°C, creating a daily temperature range of up to 15°C between dawn and afternoon. High ultraviolet radiation is expected alongside more temperate afternoon conditions as León XIV arrives at Aeroparque at 16:30.
Weather System Delivers Regional Rainfall and Threatens Planting Operations
Beyond the metropolitan area, the approaching weather system will deliver substantial precipitation to other parts of the country through Monday. Sectors of the southern Córdoba, southern Santa Fe, and northern Buenos Aires provinces expect accumulated rainfall totals of 20 mm to 40 mm. Further north, the Argentine northeast will concentrate higher totals, including approximately 50 mm in Resistencia and 80 mm in Posadas by Monday. While these generous moisture inputs can improve water availability where soils need it, they may also delay planting operations and machinery entry if surfaces remain overly saturated. Meanwhile, southwestern Buenos Aires serrano areas like Sierra de la Ventana could approach 3°C on Saturday, establishing a threshold associated with agronomic frost risks that requires special monitoring in sensitive wheat and barley crops, as well as tender horticultural tissues.
