Race-morning weather history
Cool, damp, low-wind early-May profile (13-edition average: 53F / 75% humidity / 4 mph at the 7 AM start, highs near 69F) — heat risk lives in the back half of the field. Wide year-to-year start spread (36F in 2026 vs 59F in 2025); rain at the start in 2019 and 2022. Hard gaps: no editions 2004-2008 or 2020-2021. Wyndo tracks what this calendar slot has actually served up at the start hour — temperature, dew point, wind, and rain — including the years when weather canceled or disrupted the race, and reads the live forecast for the start once the race confirms its schedule and race week arrives.
