Weather in Seoul in July
July in Seoul is hot, humid, and very wet. Average daytime temperatures hover around 85°F (29°C), often feeling even warmer due to the high humidity, which can reach 80-90%. Nighttime lows rarely drop below 72°F (22°C). Expect frequent and heavy rainfall, as July is the peak of the monsoon season, with an average of 14-17 rainy days and over 15 inches (380 mm) of precipitation. There's ample daylight, with sunrise around 5:30 AM and sunset around 7:45 PM, offering long days for exploration between the rain showers.
What to wear in Seoul in July
Lightweight, breathable fabrics are your best friends in Seoul's July heat and humidity. Think cotton, linen, and moisture-wicking materials. While Seoul is a modern city, modesty is still appreciated, particularly when visiting temples or more traditional areas; shoulders and knees should generally be covered. Comfort is key for walking and navigating public transport, so prioritize practical footwear over high fashion.
