| Threshold | Course | Length | Width | Surface |
|---|---|---|---|---|
| 01 | 10° | 2,743 m (9,000 ft) | 46 m (150 ft) | asphalt |
| 19 | 190° |
The course is derived from the runway designator (number × 10), not from a survey - the actual magnetic bearing can differ by a few degrees.
Declared distances (TORA, TODA, ASDA, LDA) are published in the national AIP - they are not part of this table.
Climate at Selfridge Air National Guard Base Airport (Mount Clemens) - statistics from METAR reports
What the METAR reports from KMTC for 2023-2025 show - counted hour by hour.
We computed these statistics from 26,012 METAR reports issued by KMTC in 2023-2025. VFR conditions prevailed 78% of the time, MVFR 14% and IFR or LIFR 7%. Best month for VFR flying: July (89% of hours VFR). Most IFR and LIFR hours: January (19%).
Through the day, IFR or LIFR conditions are most frequent around 14:00 UTC (10% of reports at that hour) and least frequent around 02:00 UTC (5%).
Fog (FG) was reported on 18 days a year on average, most often in January. Thunderstorms (TS) occurred on 21 days a year on average, and snowfall on 51.
The wind most often blows from W (270°) - 9% of reports. Calm (0 kt) made up 11% of reports, and gusts of 25 kt or more appeared in 2%. Warmest month: July (average high 27.7 °C); coldest: January (average low -4.3 °C).

Runway headings and wind
The thresholds are oriented as follows: 01/19 on 10° and 190° magnetic. A threshold designator is its magnetic heading divided by ten (ICAO Annex 14), so the runway axis can be read straight off the numbers.
For the 01/19 axis, wind from the east (around 100°) or from the west (around 280°) blows perpendicular to the runway and produces the largest crosswind component. Wind from around 10° or 190° acts along the runway, as a headwind or a tailwind. The decoder on this page computes those components automatically from the current METAR.
METAR and TAF for KMTC
Weather reports for Selfridge Air National Guard Base Airport (Mount Clemens) are published under the ICAO code KMTC. A METAR is an observation of current conditions, usually issued every 30 or 60 minutes; a TAF is a forecast for the airport area, typically covering 9 to 30 hours.
The decoder breaks the KMTC report down into its parts: wind direction and speed including gusts and variability, visibility (including CAVOK and directional minimum visibility), weather phenomena by WMO code, cloud layers with their bases, temperature and dew point, QNH pressure, and the resulting flight category - VFR, MVFR, IFR or LIFR - using FAA thresholds.
Not every airport issues its own reports; many smaller airfields have no weather station. If no current data is available for KMTC, check the nearby airports listed below.
Reports always use UTC (the Z suffix). The America/Detroit zone is GMT-05:00 in winter and GMT-04:00 in summer - that is the shift to apply to the time in the report to get local time at the airport.
The closest airports in the database, measured in a straight line from the reference point, are Coleman A. Young Municipal Airport (Detroit) (KDET, 27 km), Oakland Troy Airport (KVLL, 29 km), Windsor International Airport (CYQG, 39 km). When no report is available for KMTC, they usually give the best approximation of conditions in the area.
