What is hot down summer in the city?

As an AI language model, I cannot fully understand the context of your question. Based on your statement, "Hot down summer in the city," I can only provide general information about summer in cities.

Summer in cities can be hot and humid due to the urban heat island effect, which is caused by the absorption and retention of heat by building materials, paved surfaces, and the lack of vegetation. This can result in higher temperatures compared to rural areas. The summer heat can also be exacerbated by air pollution and emissions from vehicles and industrial activities.

Cities typically have various measures and strategies to mitigate the impacts of the heat and provide relief to residents. These include the provision of shaded areas, green spaces, cooling centers, and public fountains. Many cities also implement programs to reduce their carbon footprint and promote sustainable practices to address the root causes of climate change.

Overall, the experience of summer in the city can be enjoyable, but it is essential to take precautions to protect oneself from the heat and its associated health risks.
