Runway 15 — favored by the wind (4 kt at 140° true)
Based on wind only — no traffic or ATIS to confirm. No D-ATIS feed here — a voice ATIS/AWOS may exist; check the frequency. ADS-B tracking just started here — traffic history is still building.

KGRF field & runways
Gray AAF (Joint Base Lewis-Mcchord), Joint Base Lewis Mcchord, Washington. Field elevation 301 ft. Class D airspace. Towered. Private use. Magnetic variation 16.0°E on record, 14.8°E today.
The FAA's variation of record is the number this field was surveyed against; the second is where north points now, from WMM2025. It is moving 0.122°/year west — about 1° every 8 years — which is why runway numbers eventually stop matching their pavement.
| Runway | True | Magnetic | Number | Length | Surface | Pattern | Notes |
|---|---|---|---|---|---|---|---|
| 15 | 167.1° | 152.3° | matches rule gives runway 16 in ~22 yr | 6,124 ft | ASPH | ILS | |
| 33 | 347.1° | 332.3° | matches rule gives runway 34 in ~22 yr | 6,124 ft | ASPH |
