How often does it rain in Houston?
Houston records around 1914mm of rain a year, spread across about 163 days — roughly 45% of all days, or 14 days in an average month. In practice that makes rain a regular feature of running in Houston 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 May, averaging 223mm across about 17 rainy days. The driest is February, with 96mm over roughly 12 days. Average lows bottom out around 7.4°C in January — long-sleeve and light-glove weather rather than full winter kit. At the other end, August averages 33.1°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.
