How often does it rain in Helsinki?
Helsinki records around 782mm of rain a year, spread across about 144 days — roughly 39% of all days, or 12 days in an average month. In practice that makes rain a regular feature of running in Helsinki 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 August, averaging 83mm across about 13 rainy days. The driest is March, with 45mm over roughly 11 days. Average lows in January drop to -5.7°C, cold enough that gloves, a headband and a thermal base layer make a real difference on early runs. Summer highs peak around 20.5°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.
