It is 19.2°C (66.6°F) at 21:00 local on Friday 2 October.
Commentary: A temperature so agreeable even the HOA has nothing to say.
Our synoptic decoder reads air temperature only, so this station reports no dew point, wind or pressure here.
Not in the current ranking: this station has not reported a qualifying reading since 05:46 UTC.
Its highest placing today was 3,162nd of 8,609, reached at 05:01 UTC.
Insufficient recent observations to produce a 24-hour temperature chart.
We hold a record for 2 months here so far, September and October. The rest of the year fills in as this station reports through it.
At 21:00 it was 19.2°C. By 21:00 it was 19.2°C. The night never stood a chance.

Means are of the readings we stored, weighted by how often this station reported, so they are not daily averages and not climate normals.
Highest 35.1°C, lowest 17.6°C, mean 24.1°C. 6 days recorded from 10 readings.
These are not official records. They are the highest and lowest readings this site has stored for Posadas Aero. since September 2026, across 6 days we hold a reading for. Official climatological records are adjudicated by national meteorological services and by the WMO.
Posadas Aero. (SARP) is a SYNOP weather station in Argentina, 131 m above sea level, about 5 km from Posadas.
We have kept a daily record here for 6 of the 8 days since 26 September 2026, from 10 observations.
The same record at three widths, picking up where the last 24 hours above leaves off. Each period is summarised from the grain that suits it, so nothing here is one reading repeated thousands of times into the page.
Each reading as it arrived, newest first, with what our quality checks did with it. A reading we did not count is shown struck through with the reason.

Over the last week we have readings for 5 days here, running from 17.6°C to 31.2°C, a spread of 13.6°C.
Its best placing today was 3,162nd hottest of the 8,609 stations reporting.

We have readings for 6 of the 8 days since we started storing this station on 26 September 2026.
It is on a run of 1 day now. Its longest unbroken run is 4 days.
This station lies about 3,000 km south of the equator.

Live reading from the station, after our quality checks
Not right now: it is 3,175th of the 8,639 stations reporting to us. Its best position since we started watching is 96th of 8,928. We rank the stations that report to us, which is not the same as every place on Earth.
Our live rankings
Right now it is 11th hottest of the 95 stations we track in Argentina.
Our live rankings
Readings here arrive through NOAA WMO SYNOP bulletins. SYNOP is the surface synoptic report that national weather services file to the WMO, typically at the main hours of 00, 06, 12 and 18 UTC and often three hourly between them. It covers places with no airport, which is why the coldest readings on Earth arrive this way.
| Figure | Source | Type |
|---|---|---|
| Latest reading, today so far | NOAA Aviation Weather Center (METAR) and NOAA NWS WMO bulletins (SYNOP) | Measured, station |
| Nearby stations and distances | Computed from station positions in our own database | Calculated |
Every reading on this page has passed the checks below. A reading that fails any of them is stored as refused and can never be ranked, shown as a record, or counted in a daily high or low.
91 readings from this station have been refused in the 8 days since readings began being logged against individual stations.
A reading with no usable latitude and longitude is discarded. It cannot be ranked, mapped, or compared with its neighbours, and a temperature with no place is not an answer to which place is hottest.
Some feeds fill an unknown position with a stand-in value such as 99.99 degrees or an elevation of 9999 m. Those are not coordinates. They are caught separately from a missing position because a station placed at a fake point has no neighbours, so the neighbour check below can never see anything wrong with it.
SYNOP arrives as files that are only re-read when they change. A file that has stopped being updated is set aside whole, before any reading inside it is considered.
Different networks get different windows, because they report at different rates: 2 hours for METAR, which transmits continuously, and 9 hours for SYNOP, which reports at 00, 06, 12 and 18 UTC. A single rule would have discarded the entire synoptic network, including every station in Antarctica.
The last 7 days we recorded: 6 days recorded, 10 readings. From the daily highs and lows we recorded.

Observations stored by HottestAndColdest. A day we were not yet tracking is shown as an empty square, and says nothing about whether the station reported.
Anything above 56.8 °C or below -95 °C is refused. The ceiling sits just above the highest reading WMO accepts, so a genuine new world record would be refused here too: a record needs adjudicating, not a live tile on a home page. The floor is deliberately further from its record, because the Antarctic plateau is thinly instrumented and a real extreme there has far less around it to corroborate it.
A change of more than 15 °C from this station's previous reading within 60 minutes is treated as a failing sensor. The limit is set from measured data: real weather reaches about 12 °C in an hour at desert sunrise or under a thunderstorm outflow, and the faults found were 20 °C and more.
A reading more than 12 °C from the median of other stations within 150 km is refused. It needs at least 3 neighbours to run at all, so it protects dense networks and can say nothing about an isolated station, which is why the other checks above have to stand on their own.
