How often does it rain in Barcelona?
Barcelona records around 636mm of rain a year, spread across about 82 days — roughly 22% of all days, or 7 days in an average month. Rain is rarely the thing that stops a run in Barcelona. You can plan a training week without building it around the forecast, and a packable jacket is more insurance policy than staple.
The wettest month is October, averaging 105mm across about 9 rainy days. The driest is December, with 25mm over roughly 4 days. Average lows bottom out around 4.9°C in January — long-sleeve and light-glove weather rather than full winter kit. At the other end, July averages 28.7°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.
