• Impact: Comfortable for outdoor activities, though occasional rain showers in late spring can make the air feel slightly damp.

Summer (June to August)

2. How Humidity Impacts Daily Life in Busan

• Clothing Choices: During the humid summer months, lightweight, breathable fabrics like cotton and linen are essential. In winter, the dry air may require moisturizing products and humidifiers to maintain skin health.
• Housing Considerations: High humidity in summer can lead to mold and mildew in homes, especially in poorly ventilated areas. Many residents use dehumidifiers or air conditioning to manage indoor moisture levels.
• Food Storage: Humidity can affect food storage, particularly in summer. Refrigeration is crucial for perishable items, and airtight containers are recommended to prevent spoilage.

• Festivals and Events: Despite the humidity, summer is a lively time in Busan, with events like the Busan Sea Festival and the Busan International Rock Festival. Locals and visitors embrace the weather and adapt accordingly.
