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 Fort Simpson 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.
Fort Simpson Arpt (CYFS) is a METAR weather station in Canada, 174 m above sea level.
We have kept a daily record here since 22 September 2026, every one of the 47 days this site has existed. We have stored 1,167 observations across the 46 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.
Recent readings
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.

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.
| Figure | Source | Type |
|---|---|---|
| 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), 1957 to 2025 at this site and its predecessors, and our own observations, 47 days | Measured, station |
| Nearby stations and distances | Computed from station positions in our own database | Calculated |
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.
