Oslo weather at a glance

• Oslo sits by a fjord with forests and hills nearby, so **wind, damp air, and day–night swings** can change comfort quickly.
• Winter (Dec–Feb) is long and cold with snow/ice potential—**traction + waterproofing** matter as much as warmth.
• Spring (Mar–May) warms slowly. April improves, and May becomes clearly walkable, but wind still calls for layering.
• Summer (Jun–Aug) is mild to warm and great for outdoors; evenings can cool down, so a thin layer helps.
• Autumn (Sep–Nov) starts well in September, then turns wetter, windier, and darker into November.

Spring (slow warm-up): winter linger in March, better walks by May

Avg low -3–7°C / high 3–16°C · Variable; snow/rain mix possible early

• Wind can keep it feeling chilly even in sunshine.
• Melt-and-refreeze can make paths slippery in early spring.
• By May, parks and long walks feel much easier.

Suggested outfits
