Beijing, China

Beijing - The best and worst times to visit
Insights you need to know

Best times

• September and October
  Enjoy blue skies, pleasant temperatures, and low humidity
  
  
• Second best: May
  It boasts sunny skies plus comfortable temperatures and humidity.
  
  
• Major exemptions for the two above periods
  Avoid the first week of May and October. Domestic tourists flood Beijing for the May Day and National Day public holidays.

Least desirable times

• July and August
  Tourist crowds, air pollution, hot temperatures, high humidity, and heavy rainfall can ruin your vacation.
  
  
• December to March
  Freezing temperatures coupled with wind create bitterly cold weather. And, winter is one of the two worst seasons for air pollution (summer being the other).

More insights
April is chancy because massive sandstorms can sweep down from the Gobi Desert.

In general, avoid national public holidays because transportation and hotel availability will be scarce. Remember, Chinese like going home for the holidays.
