How often does it rain in Baltimore?
Baltimore records around 1496mm of rain a year, spread across about 139 days — roughly 38% of all days, or 12 days in an average month. In practice that makes rain a regular feature of running in Baltimore 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 July, averaging 191mm across about 15 rainy days. The driest is November, with 81mm over roughly 8 days. Average lows in January drop to -2.2°C, cold enough that gloves, a headband and a thermal base layer make a real difference on early runs. At the other end, July averages 30.3°C highs — hot enough that early morning and evening are the sensible windows, and hydration matters more than waterproofing.
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.
