1. Rainy-Day Strategy Basics
On rainy days, minimize transfers and keep indoor activities clustered. A stable flow of museum, cafe, and shopping blocks reduces weather stress and preserves energy.
2. Indoor Planning by City
Seoul works well with museum and complex-mall combinations. Busan benefits from aquarium and indoor exhibition routes. In Jeju, connect museums and hands-on indoor experiences in one area.
3. Gear and Mobility Checklist
Leave earlier, prepare quick-dry shoes and spare socks, and keep electronics in waterproof pouches. Lightweight rain gear is often more practical than large umbrellas in crowded areas.
4. Budgeting for Rainy Days
Expect higher indoor ticket and cafe spending. Reserve 15-20% of daily budget as weather response buffer and compare online ticket prices before walk-in purchases.
5. Recovery Plan
Design each day with one must-do and two optional backups. Fast switching beats perfect planning. Shared decision rules with companions keep the trip smooth under changing weather.
