I'm going to visit America in the summer vacation. What's the weather like in Washington, new york, Boston and Los Angeles in July and August? What should I pay attention to when dressing?

The weather in Washington is similar to that in Jiangsu coastal areas, and so are new york and Tianjin, both of which are hot. The weather in Boston is equivalent to Yingkou. Sometimes it's hot and sometimes it's cold. You need to prepare a coat.

Los Angeles is in Southern California. Summer is not very hot, but it is very dry.

Current computer, camera charger, etc. Generally, it is 100-240V, and no transformer is needed, but a plug-in converter is absolutely necessary.

Shopping in these areas needs to pay sales tax, and things worth 100 yuan probably need to pay 105- 1 10.

You have to pay sales tax for eating. Besides fast food, you have to pay a tip of 15%-20%.
