Over the past 10 years, Frankfurt Marathon runners have faced temperatures ranging from 8\u00b0C (47\u00b0F) on cooler years to 17\u00b0C (62\u00b0F) in warmer editions. The median temperature of 13\u00b0C (55\u00b0F) puts this race in the neutral category for running conditions.
Wind speeds average 12 km/h during race hours, with peak gusts reaching 19 km/h in challenging years. Humidity sits around 80%, and there is a 30% chance of rain on race day.
These conditions translate to an estimated pace impact of +2.9% compared to ideal running conditions. For a 4-hour marathoner, that means roughly 7 minutes slower than a perfect-weather day.
