Historical Weather Extremes

The extremes of Kentucky Derby weather are as varied as they are memorable. The coldest recorded Derby day morning temperature was 36°F, occurring both on May 4, 1940, and May 4, 1957. The coldest high temperature was 47°F, recorded on May 4 in both 1935 and 1957. Interestingly, in 1957, the cold conditions were exacerbated by brisk north winds of 20 to 25 mph, making it a particularly uncomfortable experience for spectators and participants alike.

The hottest Derby day was on May 2, 1959, when the temperature soared to a sweltering 94°F. Furthermore, the warmest overnight low was 72°F on May 14, 1886, which also marked the highest average daily temperature for Derby day at 79°F.

When it comes to precipitation, the wettest Derby day was May 5, 2018, with a remarkable 3.15 inches of rain. Another notably wet Derby occurred on May 11, 1918, with 2.31 inches of rain. Frozen precipitation, although rare, was observed on May 6, 1989, when sleet fell briefly.

Rain Trends and Streaks

Rain has been a frequent visitor at the Derby. Out of 150 Derby Days, nearly half have experienced rain. The longest run of consecutive "wet" Derby Days spanning a 24-hour period was seven years from 2007 to 2013. Conversely, the longest dry stretch was eight years, from 1937 to 1944.

Examining the typical race hours from 1 pm to 7 pm, the longest wet streak was six years from 1989 to 1994, while the longest dry streak during the same hours was twelve years, from 1875 to 1886.

Impact on the Race

The dynamic weather at the Kentucky Derby does more than affect the comfort of attendees; it significantly influences race outcomes. Heavy rainfall can transform the track into a muddy mess, favoring horses accustomed to wet conditions. On the other hand, extreme temperatures can affect the health and performance strategies of the horses and their teams. These weather conditions must be strategically incorporated into training and race-day decisions.
