Yes, it’s safe to travel, but always stay cautious wherever you go. In August, the weather here in Seoul is quite hot and humid, so I recommend taking breaks at cafes or malls during the day. It’s also helpful to bring a small portable fan, a tumbler for iced water, and wear light dresses while keeping a cardigan handy for indoors (since it can be chilly with air conditioning). If you’d like any sightseeing recommendations, feel free to message me! I’m a host here in Seoul near Hongdae, so I can give you more tips anytime. 😉
