I'm going to visit the United States during 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 in my clothes? The weather in Washington is roughly equivalent to that in the coastal areas of Jiangsu, and new york and Tianjin are similar, both of which are relatively hot. The weather in Boston is equivalent to Yingkou, sometimes it's hot, sometimes it's very cool, so you need to prepare a jacket.

Los Angeles is in southern California. It's not very hot in summer, but it's very dry.

At present, computers, camera chargers, etc. are generally 1-24V, and there is no need for transformers, but a plug-in converter is absolutely necessary.

There is sales tax for shopping in these areas, and you need to pay about $ 15-11 for things with a price tag of $1.

you have to pay sales tax when you eat, and you have to tip 15%-2% besides fast food.
