Race Day Weather

Average Temperature8.5°C / 47°F
Humidity80%
Wind15.6 km/h
Rain Chance40%
Typical ConditionsCool spring weather with possible rain showers

What to Prepare: April in Zurich swings between 4-15°C with frequent cloud-to-sun shifts. The lake-loop course is exposed in stretches — pack arm sleeves and a light cap. Tail-to-head wind reversal at the lake turnaround can shave or pad PB pace by 10-15 sec/km.

Based on historical averages for race week. Use our Weather Score Calculator and What to Wear Guide for personalized advice.

Wind Impact on Race Day

Wind at 15.6 km/h can affect your marathon pace by 5-15 seconds per kilometer. Headwinds slow you down exponentially — a 20 km/h wind costs more than twice a 10 km/h wind.
