Means are of the readings we stored, weighted by how often this station reported, so they are not daily averages and not climate normals. Some days were recorded before we began counting observations and contribute their high and low but not the mean.

These are not official records. They are the highest and lowest readings this site has stored for Zanjan Arpt since September 2026, across 47 days we hold a reading for. Official climatological records are adjudicated by national meteorological services and by the WMO.
Zanjan Arpt (OITZ) is a METAR weather station in Iran, 1,630 m above sea level, about 16 km from Zanjan.
We have kept a daily record here since 22 September 2026, every one of the 47 days this site has existed. We have stored 578 observations across the 46 of those days for which we also recorded a count.
Recent temperature history

Land surface temperature for 2026-11-06, from NASA GIBS. This is the temperature of the ground seen from orbit, not the air, and it is never ranked against air readings. Cloud hides the ground, so gaps are unread rather than guessed.
The warmest month on record here is July, when the highest reading has reached 40.5°C (104.9°F) on Friday, 10 July 2015.

Live reading from the station, after our quality checks
Data sources for this page
Readings here arrive through NOAA METAR. METAR is the routine aerodrome weather report, issued for aviation, typically every 30 or 60 minutes and more often when conditions change. It updates far more frequently than a synoptic report, which is why these pages have a usable chart.

Every reading we hold for Zanjan Arpt that passed the checks above, as a file. The source networks are public domain and the file carries its own attribution.
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.
No reading from this station has been refused in the last 14 days.
01
Has a real position
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.
02
Position is not a placeholder
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.
03
The bulletin itself is current
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.
04
The reading is recent enough for its network
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.

It is warmer here than in Douglas (10.0°C), San Marino (10.0°C) and Yerevan (9.0°C) at this moment. Those are the warmest capitals still cooler than here, so every other one on the list is further behind.

Is Zanjan Arpt the hottest place on Earth?
Not right now: it is 3,966th of the 8,970 stations reporting to us. Its best position since we started watching is 173rd of 9,581. We rank the stations that report to us, which is not the same as every place on Earth.
Our live rankings
Where does Zanjan Arpt rank among the hottest places in Iran?
Right now it is 101st hottest of the 119 stations we track in Iran.
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.
06
Not a jump too large to be weather
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.
07
Agrees with the stations around it
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.
