Sources and checks for this page
Live readings come from WMO SYNOP bulletins at Asuncion / Aeropuerto. Monthly means and every record on this page are computed from Meteostat and its data providers observations stored per station, per year, per month, and the capital list is GeoNames, CC BY 4.0. Nothing here is modelled, interpolated or estimated, and a month the archive never covered is left out rather than filled in. See how this is built.

What is the weather in Asunción right now?+−
69.8°F at Asuncion / Aeropuerto, measured at 09:00 local on Tuesday, 6 October 2026. This is the live reading from the station this page reads, after our quality checks. It is an observation rather than a forecast: it says what the weather IS, not what it will be.
When did temperature records begin in Asunción?+−
The archive held here for Asunción, Paraguay starts in 1973, which is 52 years of record, and 17,941 stored daily values, each one a maximum or a minimum.
Which station measures Asunción's temperature?+−
Asuncion / Aeropuerto (SGAS), 101 m above sea level. Every figure on this page comes from that one station rather than from a city-wide average, so it is a measurement at a known place rather than an estimate for an area.
How is the temperature measured and checked?+−
Readings arrive from WMO SYNOP bulletins and are quality controlled before they appear: a value outside a plausible range, or one that jumps further than air can move in the time between readings, is rejected rather than published. Every figure shows its source and the time it was observed.
Are there gaps in Asunción's record?+−
The record runs from 1973 to 2025, and it is not equally deep across the year: the thinnest of the 12 months has 22 years of readings behind its average and the fullest has 31. Gaps are left as gaps: a month the archive never covered is omitted rather than filled in, which is why some months on this page carry no record.
Is Asunción getting hotter?+−
In its hottest month it has. Across 26 Januarys between 1988 and 2026, the average January high at Asuncion / Aeropuerto has risen about 0.5°F per decade. That is a straight-line fit through this one station's record: it is not corrected for a station that moved or changed instrument, and it is a description of the readings rather than a climate attribution.
How does Asunción compare with other capitals?+−
It is the 54th warmest of the 224 capital cities with a full twelve months of record here, ranked on annual mean rather than on any single day, and 100th by the width of its annual swing. Male, Gustavia, Charlotte Amalie sit closest to it on that ranking.
