Cape Verde stays warm and dry essentially year-round, and January adds one specific advantage.
The steady trade winds that make Sal and Boa Vista genuinely excellent for windsurfing and kitesurfing settle into one of their most reliable stretches of the year.

Before You Go: Practical Tips for January Travel
- Book Southern Hemisphere hot destinations in January, like Sydney and Rio, early, since local summer holidays push prices up quickly.
- Pack for humidity as much as heat. Lightweight, breathable fabrics matter more than the number on the forecast.
- Bring reef-safe sunscreen and reapply more than feels necessary; Southern Hemisphere UV, in particular, is stronger than the temperature alone suggests.
- If you're new to long-haul travel, our travel tips for first-time flyers cover the basics worth knowing before a long January getaway.
- Check entry requirements early. Rules vary by nationality and destination, and January's most popular destinations can see visa or entry rule updates year to year.
- Confirm your accommodation's exact location before booking during peak season, since January's most reliable destinations are also its most heavily booked.
