How often does it rain in Detroit?
Detroit records around 943mm of rain a year, spread across about 131 days — roughly 36% of all days, or 11 days in an average month. In practice that makes rain a regular feature of running in Detroit rather than an exception — close to one day in two. A decent waterproof and a peaked cap earn their place in the kit bag year-round.
The wettest month is June, averaging 94mm across about 12 rainy days. The driest is February, with 60mm over roughly 9 days. Average lows in February drop to -6.7°C, cold enough that gloves, a headband and a thermal base layer make a real difference on early runs. Summer highs peak around 27.9°C in July, comfortable for most daytime running.
Those are ten-year averages, not a forecast. What actually matters on the day is the next twelve hours — which is what the live verdict and hourly strip at the top of this page are for.
