KSMO field & runways
Santa Monica Muni, Santa Monica, California. Field elevation 170 ft. Class D airspace. Towered. Magnetic variation 12.0°E on record, 11.4°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 0.078°/year west — about 1° every 13 years — which is why runway numbers eventually stop matching their pavement.
| Runway | True | Magnetic | Number | Length | Surface | Pattern | Notes |
|---|---|---|---|---|---|---|---|
| 21 | 224.4° | 213.1° | matches rule gives runway 22 in ~25 yr | 3,500 ft | ASPH | left | |
| 3 | 44.4° | 33.1° | matches rule gives runway 4 in ~25 yr | 3,500 ft | ASPH | right |
