Wearing a suit in hot weather will make people feel hot, because suits are generally thick, close-fitting, not very breathable, and not easy to dissipate heat. In addition, wearing a suit requires a tie or bow tie, which will also increase the oppression of the neck and the accumulation of heat.

However, in some occasions, such as formal occasions, business meetings, weddings, etc. Wearing a suit is considered a kind of etiquette and formal performance. At this time, even if the weather is hot, you may choose to wear a suit. In addition, some people may be used to wearing suits on any occasion, or think that suits are a fashion match, so they will choose to wear suits in hot weather.

Generally speaking, whether wearing a suit is hot or not depends on personal preference, occasion and comfort. If a person thinks that wearing a suit will make him more comfortable, or needs to wear a suit on certain occasions, it is understandable to wear a suit even in hot weather.
