Overview
- The Servicio Meteorológico Nacional morning snapshot for Monday, August 3 showed only La Quiaca (Jujuy) below zero at −5.0°C while southern Patagonian stations registered low single-digit temperatures with high humidity.
- TN’s earlier snapshot for Sunday, August 2 reported a broader cold outbreak in the 08:00–09:00 window that it said left at least nine provinces registering temperatures below −5°C and listed La Quiaca at −4.6°C.
- Media outlets are publishing daily top‑10 lists drawn from SMN website captures that show temperature and humidity for a single hourly window rather than multi‑day averages or forecasts.
- Geography explains the split in readings because high‑altitude Andean sites like La Quiaca can hit strong negatives while Tierra del Fuego and Patagonia normally record near‑freezing, humid mornings.
- Because the rankings come from brief hourly measurements, the coldest‑city list can change day to day and SMN will keep updating stations; residents in high‑altitude and southern towns should expect cold, humid mornings that increase frost and wind‑chill effects.
