Shanghai's best travel season is March-May, Oct-Nov. During this time, the weather is comfortable, with temperatures between 15-25°C, ideal for outdoor activities. Core attractions like 外滩, 东方明珠, and 豫园 are all pleasant to visit. Check the forecast before your trip to avoid extreme weather.
For clothing, lightweight clothing works by day, with a light jacket for mornings and evenings. Shanghai's UV is strong — bring high-SPF sunscreen, sunglasses, and a wide-brim hat. Choose slip-resistant sneakers for long walks. If you plan to visit 东方明珠, bring a windbreaker.
Value windows: Avoid holidays and weekends — weekday travel is 30-50% cheaper on flights and hotels. Book flights 1-2 months ahead for the lowest fares. Stay near 外滩 for convenience and reasonable prices. Budget reference: 5 days, 4 nights approximately 3000-7000 RMB/person.
