How often does it rain in Bristol?
Bristol records around 938mm of rain a year, spread across about 156 days — roughly 43% of all days, or 13 days in an average month. In practice that makes rain a regular feature of running in Bristol 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 December, averaging 100mm across about 15 rainy days. The driest is April, with 51mm over roughly 10 days. Average lows in January drop to 2.4°C, cold enough that gloves, a headband and a thermal base layer make a real difference on early runs. Summer highs peak around 20.7°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.
