Ciudad Acuña has a hot semi-arid climate.
Dry country, big sun, modest rain — here's what that means in plain terms.
What this climate feels like
The four things a regular visitor actually wants to know:

Lows near 5°C in December.
About 504 mm of rain a year. Wettest in September.
A roughly even mix of sun and cloud.
What "hot semi-arid" means
Climate scientists sort every place on Earth into about 30 climate types, based on how hot, cold, wet and dry it is across the year. Ciudad Acuña's type — hot semi-arid — sits in the broad family of dry climates — deserts and steppes.
Researchers write climate types as a short letter code. Here is what each letter means:

Has Ciudad Acuña's climate type changed?
Stable — Ciudad Acuña's climate has held the same type between the 1971–2000 and 1991–2020 normals. The label is steady; the climate beneath it is still warming.
What this climate means for you
Native grasses, drought-tolerant shrubs and hardy fruit trees (figs, pomegranate, olives) do well. Vegetable gardens need irrigation.
Cool half of the year is comfortable; summer is hot and dusty. Watch for wet-season storms during the short rainy stretch.
Hot, dry and dusty — drought is a recurring issue. Comfortable winters; tough, sun-blasted summers.
Where these numbers come from
The climate type and the month-by-month figures on this page are computed from Ciudad Acuña's measured 30-year climate normals (1991–2020) — the same official records behind Ciudad Acuña's main climate page, so the two always agree.
Long-range climate maps measure things slightly differently and can place a city in a neighbouring category. Where they differ, this page uses the measured station record as the climate today.
