Current pilot readout for KMKS
KMKS is currently MVFR with winds from 030° at 5 knots, visibility 10+ statute miles, and a 3,000 ft ceiling. the wind favors northeast-facing runway ends (05). Density altitude is approximately 650 ft (field elevation 74 ft). KMKS does not publish a TAF. The nearest TAF station is KCHS, about 17 nm away.
KMKS by the numbers
What the long-run records say about flying here, computed for this airport alone.
KMKS reported VFR in 81% of daylight observations over 20 years, about 243 flyable days a year. July is the most reliable month and December the least, with IFR or worse 13% of the time. When conditions drop it is usually low ceilings rather than fog (ceilings under 1,000 ft 7% of hours, visibility under 3 miles 3%).
Over 20 years of hourly winds, runway 23 had the best headwind 52% of the time, runway 05 48%, and winds were calm 41% of hours. Winds most often blow from the north. Crosswind on the best available runway topped 15 kt in under 1% of hours.
Thunderstorms were reported on about 82 days a year. 66% of storm hours fall in June, July and August, peaking in July when storms were in the air 5% of the time.
Fog was reported on about 31 days a year, and fog or mist on 194. November and December are the foggiest months, with fog in 10% of hours, against 6% in June.
Field elevation is 74 ft, but on a median summer afternoon the air performs like 1,816 ft, 1,742 ft higher. Plan for a longer takeoff roll and a weaker climb from June to August.
Winds were calm 40% of the time and averaged 3.5 kt overall. March is the windiest month (mean 4 kt) and August the calmest.
