The hottest, coldest, wettest and snowiest days Maipú has
recorded — the outer limits of what its weather can do, and how far
they sit beyond a normal day.
Based on 20 years of daily weather observations (2005–present), from the Quinta Normal station 12 km away. Updated through August 2025 — an all-time extreme only changes when a more extreme day actually occurs, so some dates are old. That is normal, not stale data.
The four kinds of extreme
The hottest, coldest, wettest and snowiest single days Maipú
has recorded — each shown against what a normal day that time of year
looks like.

In plain terms
Across the record, Maipú has reached as high as 101°F and as low as 26°F. A single day has delivered over 3 inches of rain. Those are the outer edges worth knowing if you are moving here, planning a trip, or thinking about a house.
Methodology & sources
Temperature & precipitation — 1991–2020 normals computed from 30 years of daily observations at Arturo Merino Benitez Intl, a weather station, about 14 km from the city centre. The underlying daily records come from NOAA's global station network.
