The sweet spots for visiting Shanghai are during the spring and autumn. From late March to May, the city’s weather is fairly mild, and you can see cherry blossoms in places like Century Park. October and November are arguably even better, as the humidity of summer has faded and the "plum rain" season is over, leaving you with crisp air and clear blue skies. 

It is vital to avoid the major public holidays if you want to dodge overwhelming crowds. The Chinese New Year (usually in January or February) and the National Day "Golden Week" (the first week of October) see hundreds of millions of people travelling. During these dates, popular spots like the Bund or Nanjing Road can become incredibly congested. Similarly, July and August are often sweltering and coincide with school holidays, leading to long queues at major attractions and higher hotel prices. 

While many visitors rush through the city in two or three days to see the iconic skyline, staying longer is the only way to truly appreciate the layers of Shanghai. A minimum of four days is necessary to cover the essentials like the French Concession, Yu Garden, and the Lujiazui skyscrapers. However, a stay of five to seven days is much better for those who want to discover the city in depth. 

Having a full week allows you to move beyond the tourist hubs and explore quieter, lesser-known neighbourhoods like the leafy lanes of Jing'an or the creative hubs in Putuo. You will also have the flexibility to take a high-speed train to a nearby water town like Zhujiajiao without feeling like you are constantly on the move. Taking the time to wander through local wet markets or sit in several parks helps you connect with the city's authentic character rather than just ticking off famous landmarks. 

Shanghai is one of the safest major cities in the world for travellers, with a very low rate of violent crime. That said, it is always important to check your government's local travel advisory for the most up to date information. The most common issues are petty crimes like pickpocketing in busy shopping districts or at major transport hubs. 

You should be aware of a few well-known scams, such as the "tea house" or "art student" scam. This involves friendly strangers inviting you to a traditional ceremony or a gallery, only for you to be hit with a massive bill at the end. Use common sense by sticking to licensed taxis or rideshare apps and avoiding drinking in excess. Always ensure you have a comprehensive travel insurance policy to cover any unexpected medical needs or lost items.

Shanghai is a cosmopolitan city where people generally dress in a modern, stylish way. When you are out sightseeing, smart-casual clothing is the norm. If you are visiting religious monuments like the Jade Buddha Temple, it is polite to cover your shoulders and knees. This simple show of respect for local traditions is always appreciated. 

If you are invited into someone's home, remember to remove your shoes at the door. Your host will usually provide a pair of indoor slippers. When it comes to general behaviour, avoid pointing with your fingers and instead use an open hand. Showing respect through these small actions makes for a much smoother and more enjoyable interaction with the local community.

Packing for Shanghai depends heavily on the season. If you are visiting in the winter, the damp cold can feel much harsher than the temperature suggests, so bring a heavy coat, thermals, and a scarf. During the rainy months of June and July, lightweight waterproof gear and a sturdy umbrella are essential. For the hot summer, stick to breathable fabrics but avoid very revealing items like singlet or crop tops to minimise unwanted attention. 

Comfortable walking shoes are the most important item in your bag, as you will likely be on your feet for hours. If you plan on visiting a pool, standard swimwear is fine, although many spas are segregated and bathing is done nude. It is also a good idea to pack some hand sanitiser and packets of tissues, as these are not always provided in public facilities.

You can’t visit Shanghai without trying Xiao Long Bao, the famous soup dumplings that are a point of pride for the local community. These delicate parcels are traditionally filled with pork and a rich broth, while eating them is an art form in itself. Another staple is Sheng Jian Bao, which are pan-fried pork buns with a crispy base, often found at breakfast stalls. 

For a true taste of the city, head to the areas around Huanghe Road or the food markets in the Old Town. These spots are famous for "red-braised" dishes like Hong Shao Rou (pork belly), which reflects the Shanghainese love for sweet and savoury flavours. Trying these dishes at local eateries rather than just in hotels supports small businesses and gives you a much more authentic insight into the regional culture.
