The upside of a quiet December
- The big-ticket sights are walk-ins now; the summer booking scramble is gone.
- Keep the days loose — decide over breakfast, not weeks ahead.
- Early on, you can have the busiest spots almost to yourself — bring a camera.
No queues to skip, and nothing to book ahead — that's the whole point.
December weather in Oslo

- Oslo gets rain on about 15 days in December, so the odds of being caught out are real. What earns its bag space is a shell that packs to nothing, dries fast and has a hood that survives wind; a heavy waterproof is overkill and an umbrella is one more thing to carry through crowds.
