Summer in East Asia brings higher temperatures and more humidity, especially in southern regions like Hong Kong and Taiwan, where average temperatures can soar above 30°C (86°F). Coastal destinations, including the beaches of Okinawa in Japan and Hainan Island in China, are particularly popular for summer vacations. For those interested in water sports, these spots offer perfect conditions for swimming, surfing, and snorkeling. However, the summer months also coincide with the rainy season in many areas, especially in Japan and Korea. It’s a good time to explore indoor attractions like museums, shopping districts, and vibrant night markets. Southeast China, with its famous landscapes in Guilin, is lush and green during the summer, offering peaceful river cruises through the picturesque karst mountains. In contrast, northern regions like Mongolia and parts of Northeast China see milder conditions, making outdoor adventures in the Gobi Desert or the Harbin Ice Festival an appealing choice.
