KMIA Runway 12/30 — Miami International Airport
9,360 × 150 ft asphalt · true headings 119° / 299° · field elevation 8 ft
Runway 12/30 at Miami International Airport (KMIA) in Miami, FL is 9,360 ft long and 150 ft wide, asphalt, with true headings 119° and 299°. Over 2005–2025 the wind gave runway 12 the headwind 72.4% of the time and runway 30 27.6%, with a crosswind above 15 kt in 0.3% of wind hours. KMIA publishes a digital ATIS, so this page shows the runway the tower is actually using right now and builds a record of how often each end is assigned.
Runway 12/30 — current status
CLOSURE ON RECORD (TOWER TFDM)- The tower's TFDM closure record lists runway 12 and 30 closed ("12_30") since 2026-09-14 16:01Z.
- The tower's current configuration still lists runway 12 for arrivals or departures, so the closure may be partial or the record may lag. Verify with NOTAMs before flight.

No received NOTAM currently names runway 12/30 at KMIA. NOTAMs are received live from the FAA NOTAM Management Service through SWIM and recorded since Sep 19, 2026; a NOTAM issued before that and not re-issued since may be missing. Get a full briefing before flight.

No steady wind direction — no components to compute.
Components use TRUE runway headings and TRUE METAR wind. “Favored by wind” is arithmetic, not an ATC assignment.

ATIS Alerts Predicted Runway is an estimate from the TAF wind forecast and runway geometry (most headwind, crosswind penalised, tailwind over 5 kt avoided, longest runway breaks ties). It is not an ATC assignment and does not know about noise abatement, traffic flow or construction unless the D-ATIS states them. TAF issued 2320Z (7:20 PM EDT).

Runway 12/30 numbers are magnetic; the stored geometry and every wind calculation on this page are TRUE north, so they never need a variation correction. Magnetic variation here is about 7.3°W (World Magnetic Model). Displaced thresholds, declared distances (TORA/TODA/ASDA/LDA), approach lighting, PAPI/VASI, ILS equipment and traffic-pattern direction are FAA NASR fields not yet loaded — they are omitted rather than guessed.
Recorded runway use at KMIA — last 30 days
How often the tower's TFDM configuration listed each end for arrivals and departures (the tower's own statement, via FAA SWIM).
ATIS Alerts records every change of KMIA's tower TFDM configuration and turns it into a log of which runways the facility named for arrivals and departures. Recording started Sep 18, 2026 — 6 hours captured so far. Usage statistics appear once 24 hours are on record, and become meaningful after a few weeks.
Historical wind and crosswind on runway 12/30
20-year hourly climatology from the ASOS archive, computed per runway end.
From 175,290 hourly observations at KMIA (2005–2025), 144,574 with a steady wind direction (17.5% calm, variable or direction-less). One observation per clock hour; TRUE headings against TRUE wind.

Runway 12/30 closure history
Runway NOTAM history begins when the NOTAM feed goes live (next phase).
D-ATIS broadcasts recorded since Sep 18, 2026 declared runway 12 closed on 2 days and runway 30 closed on 2 days in the last 30 days. Scheduled and unscheduled closure NOTAMs, with start and end times and the official text, will appear here once ATIS Alerts records runway NOTAMs; there is no retrievable archive, so history accrues from that date forward.

Methodology and sources
Short version below; the full write-up is at Runway Intelligence methodology, and every launched airport is listed on the Runway Intelligence hub.
- Active runwayscome first from the tower's TFDM (Terminal Flight Data Manager) airport configuration, received as structured data through the FAA SWIM Cloud Distribution Service at towers that have it (KMIA does); otherwise from the airport's D-ATIS text (community relay of the FAA broadcast) with an open, tested parser, and the broadcast text is always shown. Every change is recorded, so “recorded use” is what the facility stated, never an inference. ATIS Alerts is not an FAA product and this is not FAA data; SWIM content is for non-operational use.
- Wind components use the current METAR (aviationweather.gov) against TRUE runway headings from the OurAirports/FAA runway record.
- Runway visual range, tower demand and traffic-management restrictions come from FAA SWIM: STDDS Airport Data (RVR and light settings, about 130 airports) and TFDM (15-minute runway demand, APREQ/MIT restrictions). Each block is stamped with its own time; none of it is an FAA product or a clearance.
- Predicted runway scores each open end from the TAF wind (headwind, crosswind penalty, tailwind avoidance, longest-runway tie-break); confidence falls with forecast distance, gusts and TAF age. It does not model noise abatement or flow programs.
- Climatology: Iowa Environmental Mesonet ASOS archive, one observation per hour, 45° wind sectors, percentiles via t-digest; runway geometry is today's record applied to all years. Methodology v1.
- Approaches: FAA d-TPP metafile, current charting cycle; plates link to aeronav.faa.gov. No minimums are reproduced.
- Data freshness: METAR and D-ATIS refresh every minute on this page; the D-ATIS recorder ran 1 min ago; the tower TFDM feed last delivered 11 min ago; climatology through 2025-12-31.
