77%
of daylight hours VFR, 2006 to 2025

KDAY reported VFR in 77% of daylight observations over 20 years, about 251 flyable days a year. August is the most reliable month and January the least, with IFR or worse 16% of the time.

of windy hours favor 24L, 24R

Over 20 years of hourly winds, the southwest-facing ends (24L, 24R) had the best headwind 35% of the time, runway 18 28%, and winds were calm 8% of hours. Winds most often blow from the south-southwest. Crosswind on the best available runway topped 15 kt in 1% of hours.

44
snow days a year

Snow fell on about 44 days a year and freezing rain or drizzle on 7. From December to February KDAY was IFR or worse 15% of the time, against 3% from June to August.

80%
of departures on time, June 2025 to May 2026

DAY departures left within 15 minutes of schedule 80% of the time across 7,897 flights, June 2025 to May 2026. Before 9 AM departures did best (89%) and 6 to 9 PM did worst (68%).
