How often does it rain in Dublin?
Dublin records around 923mm of rain a year, spread across about 160 days — roughly 44% of all days, or 13 days in an average month. In practice that makes rain a regular feature of running in Dublin 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 94mm across about 15 rainy days. The driest is January, with 63mm over roughly 12 days. Average lows bottom out around 3.7°C in January — long-sleeve and light-glove weather rather than full winter kit. Summer highs peak around 19.2°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.
