New York City Marathon
Race Day Weather
Cool conditions, steady tailwinds
Runners will face a cool start at 50°F, gradually warming to 56°F by the finish. With a light tailwind throughout most of the course, especially beneficial from miles 1-8 and 10-20, pacing can remain steady. Runners should consider hydration frequency given the average humidity of 50%, and adjust their strategy for headwinds at miles 22-25.
The finish is 13 miles from the start, so we forecast it at 2 points, not just the start line. At 9:00/mi, you start at 50° and finish around 1:05 PM in 56°.
