Runway 23 — favored by the wind (10 kt at 240° 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.

KLWM field & runways

Lawrence Muni, Lawrence, Massachusetts. Field elevation 148 ft. Class D airspace. Towered. Magnetic variation 15.0°W on record, 14.0°W 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 0.074°/year east — about 1° every 14 years — which is why runway numbers eventually stop matching their pavement.

Runway data from the FAA NASR 01 Oct 2026 cycle. Where NASR locates both thresholds, the true heading is the bearing between them rather than NASR's whole-degree alignment. Magnetic is that heading against *today's* declination from WMM2025, not the field's variation of record — so it can differ from the chart by the gap between the two shown above. The number painted on the runway is the one ATC uses.
Runway	True	Magnetic	Number	Length	Surface	Pattern	Notes
14	121.8°	135.8°	matches rule gives runway 13 in ~10 yr	3,654 ft	ASPH	left
23	218.1°	232.0°	matches	5,001 ft	ASPH	left
32	301.8°	315.8°	matches rule gives runway 31 in ~10 yr	3,654 ft	ASPH	left
