What to Wear When Traveling

Why destination climate matters for packing

The difference between packing well and packing poorly usually comes down to understanding two numbers: average high temperature and monthly rainfall. These two data points determine which fabrics to choose, how many layers to bring, and whether you need rain protection.

Most travelers pack based on the season at home, not the conditions at their destination. A trip to Southeast Asia in December requires completely different clothing than December in New York. Our tool provides the specific climate data you need to pack the right wardrobe for every trip.

How to use climate data for packing

Step 1: Search for your destination and select your travel month to see average temperatures, rainfall, and humidity.

Step 2: Read the layering recommendation for that climate type. Hot and humid conditions call for lightweight moisture-wicking fabrics. Cold weather requires a full three-layer system with insulation.

Step 3: Click through to the related fabric and product guides for specific gear recommendations tested by our team.

Understanding climate categories

We classify each destination-month combination into one of seven climate categories, each with its own layering strategy:

• Hot & Humid: 30°C+ with high humidity. Prioritize breathability and moisture-wicking.
• Hot & Dry: 30°C+ with low humidity. Prioritize sun protection and UPF clothing.
• Warm: 24-30°C. Light layers, minimal insulation needed.
• Mild: 18-24°C. Light layering system — merino base plus a jacket.
• Cool: 10-18°C. Full three-layer system with insulation.
• Cold: Below 10°C. Winter layering with thermal base, insulation, and weatherproof shell.
• Variable: Rapidly changing conditions. Pack for adaptability with a complete layering system.
