Better in the same region in January
If you're set on South America in January, these cities have more comfortable conditions in the same window:
If you still have to go — what to bring
- Cold: Merino base layer, insulated mid-layer, waterproof shell, grippy boots, hand warmers. Daylight is short — start mornings later, finish before sunset.
- Wet: Real rain shell (not a "water-resistant" jacket), packable umbrella, dry-bag for electronics, quick-dry layers. Pre-book indoor museums and food halls.
