Shanghai has four seasons. Summer heat peaks in July and August, and this can be an uncomfortable time for outdoor sightseeing. This is, however, the peak tourist season, and the heat doesn't matter much as indoor, air-conditioned space abounds. Spring and fall are more comfortable, and there are fewer crowds to contend with.
Winters are quite cold, especially after hours, so be sure to pack appropriately. January and February are also when Chinese New Year is staged, and hotels book up early as crowds of visiting Chinese surge into Shanghai.
The easiest way to get around in Shanghai is by taxi, which can usually be hailed on the street. Fares are affordable by Western standards, and tourists are better off trusting a taxi driver than renting their own car and braving the hectic driving conditions. The metro is also increasingly useful, with eight lines in operation and four more on the way.
Most international visitors arrive via Pudong International Airport (PVG). It's located 40 kilometers outside the city center, so transfers are essential. Meanwhile, Shanghai Hongqiao International Airport (SHA) is more centrally located, 10 mile from city center. Taxis are on hand outside the arrivals hall and are considerably more expensive than the airport buses. The Maglev train (from PVG) is the most convenient as it arrives in the city center (People's Square) in a startling eight minutes.
