The upside of a quiet January
- Walk straight into the sights that sell out in high season — no timed ticket, no queue.
- This is a wing-it month: nothing needs locking in.
- 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.

Mild — around 14°C / 58°F, with a light jacket for the evenings, with rain on about 15 days, so keep a layer handy. Daylight is short, about 10 hours, so plan the big sights for the middle of the day.
This is the value month: no need to book far ahead, and the freedom to change plans on the day is part of what you're getting.
