Pack layers for Nanjing in October—days are typically mild (15–24°C / 59–75°F) with cooler evenings; bring a light jacket and comfortable walking shoes for sightseeing in Nanjing, Suzhou, and Hangzhou. From the George Bush Intercontinental Airport (IAH) side, monitor weather alerts for late-season hurricane activity and confirm flexible ticket options if traveling during potential storm windows. For Golden Week travel, reserve high-speed rail tickets and hotels early, arrive at airports with extra buffer time, and download essential apps (WeChat, Alipay, local transit apps). Consider travel insurance that covers trip interruption and international medical emergencies. CTA: prepare smart—compare IAH to NKG flight options, pack for autumn weather, and book transfers in advance to secure a smooth October journey.
