How often does it rain in Oslo?
Oslo records around 940mm of rain a year, spread across about 137 days — roughly 38% of all days, or 11 days in an average month. In practice that makes rain a regular feature of running in Oslo 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 July, averaging 111mm across about 13 rainy days. The driest is April, with 50mm over roughly 8 days. Average lows in January drop to -5.8°C, cold enough that gloves, a headband and a thermal base layer make a real difference on early runs. Summer highs peak around 21.2°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.
