Current pilot readout for KLMO
KLMO is currently IFR with calm winds, visibility 5 statute miles, and a 700 ft ceiling. Density altitude is approximately 5,000 ft (field elevation 5,055 ft). KLMO does not publish a TAF. The nearest TAF station is KBJC, about 15 nm away.
KLMO by the numbers
What the long-run records say about flying here, computed for this airport alone.
KLMO reported VFR in 88% of daylight observations over 20 years, about 298 flyable days a year. June is the most reliable month and February the least, with IFR or worse 8% of the time. When conditions drop it is usually low ceilings rather than fog (ceilings under 1,000 ft 3% of hours, visibility under 3 miles 2%).
Over 20 years of hourly winds, runway 29 had the best headwind 59% of the time, runway 11 41%, and winds were calm 35% of hours. Winds most often blow from the west. Crosswind on the best available runway topped 15 kt in 1% of hours.
Snow fell on about 47 days a year. From December to February KLMO was IFR or worse 6% of the time, against 1% from June to August.
Field elevation is 5,055 ft, but on a median summer afternoon the air performs like 7,840 ft, 2,785 ft higher. Plan for a longer takeoff roll and a weaker climb from June to August.
Winds were calm 35% of the time and averaged 3.9 kt overall. April is the windiest month (mean 5 kt) and September the calmest.

Runway wind check
Estimated head/tailwind and crosswind for each runway end from the current reported wind.
Current wind is calm: calm wind is not a factor for runway selection, and with no wind there is no head/tail or crosswind component to compute. Live numbers return automatically once a report includes a wind direction.

“Current use” is what the facilitystates; wind components are arithmetic on the current METAR against TRUE headings; status reflects NOTAMs received through SWIM, the tower's TFDM record and the D-ATIS — a runway reads “Open” only with a complete NOTAM picture.
