Overview
- The most recent Servicio Meteorológico Nacional (SMN) morning ranking places Maquinchao (Río Negro) at the top with a measured -5.7°C and 83% humidity.
- SMN’s daily lists show the coldest locality changes day to day, with La Quiaca (Jujuy) and Malargüe (Mendoza) having led earlier in the same reporting period.
- A small group of towns—including Chapelco, El Calafate, San Carlos de Bariloche and Villa Reynolds—recur in the top-10, reflecting consistent regional susceptibility to low early-morning temperatures.
- The May 26 bulletin republished by national outlets also carries a local AMBA forecast that warns of morning fog, about 9°C at dawn, a low chance of rain and a daytime high near 16°C.
- SMN’s routine morning observations (typically between 7–8 AM) report air temperature, sensación térmica (feels-like) and humidity, metrics that inform local travel, agriculture and health advisories as austral winter begins.
