Current pilot readout for KSDF
KSDF is currently VFR with winds from 180° at 4 knots, visibility 10+ statute miles, and no ceiling reported. The tower TFDM states arrivals on runway 17R and 17L and departures on runway 17R and 17L; crosswind on the active runways is approximately 1 kt; the wind favors south-facing runway ends (17L, 17R). Density altitude is approximately 1,000 ft (field elevation 501 ft). Review the latest TAF below for forecast changes before departure.
KSDF by the numbers
What the long-run records say about flying here, computed for this airport alone.
The FAA issued 3 ground stops and 4 ground delay programs for SDF between October 2025 and October 2026, affecting 6 days. Wind was the most common reason (2 of 7). A typical ground stop lasted about 1 h 30 min.
KSDF reported VFR in 81% of daylight observations over 20 years, about 266 flyable days a year. August is the most reliable month and December 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, the south-facing ends (17L, 17R) had the best headwind 33% of the time, runway 29 29%, and winds were calm 14% of hours. Winds most often blow from the south. Crosswind on the best available runway topped 15 kt in under 1% of hours.
Snow fell on about 29 days a year and freezing rain or drizzle on 3. From December to February KSDF was IFR or worse 8% of the time, against 2% from June to August.
SDF departures left within 15 minutes of schedule 82% of the time across 23,407 flights, June 2025 to May 2026. Before 9 AM departures did best (92%) and 6 to 9 PM did worst (68%).
Over the last 30 days of recorded D-ATIS broadcasts, KSDF ran mixed configuration 63% of the time and north flow 21%. Runway 35L was named for arrivals most often (75% of recorded hours), and the configuration changed 86 times.
