Seasons & weather
Oslo runs all year
There is no bad weather, only the wrong clothes — as Norwegians like to say. Every season gives Oslo a different character, and every season is good for running. Here is what to expect and what to bring.
Spring (April – May)
3–16 °C · 14–17 hours of daylight
The city wakes up. Paths dry out, the rivers run full with meltwater and the first green comes to the forest. Mornings can be crisp, so bring a light long-sleeve layer. Higher forest trails may still hold patches of snow into May.
Summer (June – August)
15–25 °C · up to 19 hours of daylight
Long, light evenings and mild mornings — the easiest season to run. Shorts and a t-shirt are enough; bring sunscreen and water on warm days. Early starts are the quietest and coolest, and a swim in the fjord after the run is hard to beat.
Autumn (September – October)
5–15 °C · 10–13 hours of daylight
Many locals' favourite. Cool air, golden forests and few crowds. Expect some rain: a light windproof jacket is worth bringing. From October the evenings get dark early, so later runs use a head torch.
Winter (November – March)
-8 to 3 °C · 6–10 hours of daylight
Snowy parks, frozen lakes and low, beautiful light. City paths are cleared and gritted, but can be icy — we recommend shoes with good grip or simple slip-on spikes, which we can advise on. Dress in layers: a thermal base, a windproof top, gloves and a hat.
If the weather turns
Your safety comes first. If conditions are unsafe — storm, heavy ice or extreme cold — the guide will move, shorten or reschedule the run. If we cancel for weather, you get a full refund. See the cancellation policy.
