Not currently reporting
This station has not reported a qualifying observation since Tue 27 Oct 2026. This site retains what it recorded: 36 days of highs and lows from 134 readings, which stays on this page. A separate archive of daily values from 1948 is linked under data sources.
Our synoptic decoder reads air temperature only, so this station reports no dew point, wind or pressure here.

These are not official records. They are the highest and lowest readings this site has stored for SAN LUIS VALLEY REGIONAL since September 2026, across 36 days we hold a reading for. Official climatological records are adjudicated by national meteorological services and by the WMO.
SAN LUIS VALLEY REGIONAL (KALS) is a weather station in United States, 2,297 m above sea level.
We have kept a daily record here for 36 of the 46 days since 22 September 2026. We have stored 134 observations across the 35 of those days for which we also recorded a count.
Recent temperature history
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.
By month, from our own record
For the long record, see SAN LUIS VALLEY REGIONAL’s average and record temperature for every month.
| Month | High | Low | Mean | Days | Readings |
|---|---|---|---|---|---|
| October 2026 | 22.2°C | −6.1°C | 9.6°C | 27 | 103 |
| September 2026 | 21.1°C | 3.9°C | 11.8°C | 8 of 9 | 31 |
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.

Comparing the ten most recent years in our record (2016 to 2025) with the ten earliest (1948 to 1957), the average daily high is 1.5°C warmer. That is a comparison of two periods in this station's own record, not a climate attribution.
Data sources for this page
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.

|---|---|---|
| Latest reading, today so far | NOAA Aviation Weather Center (METAR) and NOAA NWS WMO bulletins (SYNOP) | Measured, station |
| All-time, monthly and on-this-day records | NOAA NCEI Global Historical Climatology Network daily (GHCN-Daily), 1948 to 2026 at this site and its predecessors, and our own observations, 36 days | Measured, station |

How these readings are checked
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.
