Weather: July and August are the hottest months in Beijing, and temperatures may rise to 40 °C (104 °F) during daytime. Bring an umbrella as July has an average 185mm (7 inches) of rainfall, which often comes in thunderstorms
Clothing: It's shorts and t-shirts weather all the time with even night-time temperatures in the 20s °C (70s °F).
Midsummer is prime time in Beijing. With endless sights and a nonstop number of events, no visitor has done it all in Beijing in July.
The Summer Palace: Bygone emperors visited the summer palace,blooming with greenery and lakes as an escape from the summer heat, now Beijing tourists can too. Encompassed by bushels and sky scraping trees that embrace visitors with shade and winds pushing natural air conditioning off of the water, most tourists discover why emperors visited this locale during the summer before the tour guide has a chance to explain.
The Chengde Summer Palace: If you want to visit a cooler place to escape the heat in the city, the Summer Palace in Chengde, a day trip away, is a good choice.
Tian'anmen Square & the Forbidden City: Though each landmark in Beijing has a history to be revered and respect, there are just too many. Kill two birds with one stone in the very heart of Beijing. Tian'anmen Square, opposite the Forbidden City, brims with Chinese pride, history and culture. This historic landmark is an excellent appetizer before visiting its larger neighbor.
The Forbidden City: Enter into the enormous gates of a site once forbidden to any but royalty and aristocracy. The Forbidden City has a history stretching back farther than most in Beijing. With a ten meter high defensive wall, 178 acres, 600 year old architecture and palaces and courtyards galore, it is more than worth the small price of admission.
The Temple of Heaven: The holiest of China’s temples, the Temple of Heaven was a gateway to paradise and in some ways still is. Climbing the sacred steps and rising towards the elevated platform invokes a sense of reverence. Built with celestial and lunar rationale, no time is better than the summer to observe this holy site in Beijing.
Be aware: July is in the peak tourist season in Beijing, so booking hotels and flights in advance is recommended.
