Heat in the US is as varied with respect to humidity as is the heat in Asia. Hence the question is not accurate. I live in the Southeastern U.S., and the humidity in the southeast is unbearable in the summer.
The sweltering heat caused many deaths in New York City. With high temperatures and high humidity, summer felt sweltering.
relative humidity causes heat and therefore discomfort
The phrase "It's not the heat, it's the humidity" is commonly used in the summer months because high humidity levels can make the air feel hotter than it actually is. Humidity affects how efficiently your body can cool itself through sweat evaporation, leading to a feeling of discomfort and increased perception of heat.
The raise in humidity after rainfall often makes the heat seem much more oppressive.
During summer in a hot and humid city, you can expect high temperatures, frequent thunderstorms, increased humidity levels, and the need for staying hydrated and seeking shade to avoid heat-related illnesses. Outdoor activities may be more challenging due to the intense heat.
It depends on the humidity, heat, if it has rained, etc. Their can be different conditions for the sidewalk to separate.

Alabama has a humid subtropical climate, which means it has high humidity levels, especially during the summer months. While temperatures can get quite hot, the humidity can make it feel even hotter and more uncomfortable.
During the summer, warmer temperatures cause water to evaporate from oceans, lakes, and rivers, increasing humidity. In contrast, cold winter air can hold less moisture, leading to lower humidity levels. Summer also tends to have more rainfall, contributing to the overall humidity in the air.
High relative humidity in the summer can make people feel more uncomfortable because it reduces the body's ability to cool itself through sweating. When the air is already saturated with moisture, sweat doesn't evaporate from the skin as efficiently, leading to a feeling of stickiness and increased perception of heat.
