Race-morning weather history
Early-May Cincinnati: ~56F humid starts, highs near 70F. The 2023 edition ran into thunderstorms with street flooding and lightning, prompting a mid-race shelter-in-place request. 2020 in-person cancelled; 2021 held in late October — both gaps in the May record. 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 race week arrives.
