Why is Taiwan's summer so humid?

Many people who spend their first summer in Taiwan may find it's not just the high temperatures they struggle with, but also the constant sticky, damp feeling in the air. Even after just taking a shower, you start sweating again shortly after going out; clothes hung out all day still aren't completely dry; and corners of rooms, shoes, and closets might develop a musty smell due to the humidity. Why is Taiwan's summer so humid? It's related to its geographical location, monsoons, and hot weather. Taiwan is an island surrounded by the sea. Evaporation from the ocean increases the moisture content in the air, making Taiwan's climate generally more humid than inland areas. The Pacific warm air mass that affects Taiwan in the summer is inherently warm and humid; the summer monsoon also brings moisture from the sea to Taiwan. This is why the air can feel muggy even when it's not raining. High temperatures make the body feel stickier When the weather is hot, the body sweats to dissipate heat. Normally, sweat evaporation helps carry heat away from the body. However, when the air humidity is high, sweat evaporates less easily and can remain on the skin and clothes. Therefore, even if the actual temperature isn't much higher, the body feels muggier, stickier, and more uncomfortable. This is a common feeling during Taiwan's summer: it's not just "hot," but "hot and humid." Why does it often rain suddenly in the summer? In addition to being influenced by the Pacific subtropical high-pressure system, Taiwan's summers also have abundant moisture. During the day, the ground heats up, causing hot air to rise, which easily forms convective clouds and short, heavy downpours in the afternoon. Furthermore, plum rains, the southwest monsoon, and typhoons can bring even more moisture and rainfall. Taiwan is located in the East Asian monsoon region, experiencing significant weather changes during summer and between summer and autumn, making the feeling of humidity even more pronounced. Therefore, even if the weather is clear when you go out in the morning, you might encounter heavy rain in the afternoon. Carrying an umbrella is usually more reliable than just looking at the morning sky. What are the effects of humidity on daily life? Living in Taiwan, humidity most often affects daily life rather than just meteorological figures. For example: · Clothes and towels take longer to dry · Shoes, closets, and rooms easily develop a musty smell · Books, paper, and leather items may become damp · Bathroom walls are prone to mold growth · Food spoils more easily after opening · Rooms can feel muggy even when not hot Renters are particularly prone to these issues. If a room has poor ventilation, no external windows, or is on a lower floor, the humidity can be even more noticeable. The simplest method is to maintain air circulation. When the weather is suitable, open windows or use a fan to speed up indoor air circulation. If a room is persistently damp, you can use the dehumidifying function of air conditioners or a dehumidifier. However, when using a dehumidifier, close doors and windows, and pay attention to water tank and electrical safety. Desiccants can be placed in closets, shoe cabinets, and drawers, but these usually only handle small areas and cannot completely replace ventilation or dehumidifiers. After showering, turn on the exhaust fan as soon as possible to prevent moisture from lingering in the bathroom. Clothes don't necessarily dry faster the longer they hang On humid or rainy days, continuously hanging clothes indoors without air circulation might only cause them to develop a musty smell. When hanging clothes, space them apart and use a fan or dehumidifying equipment. If clothes already have an odor, rewashing is usually more effective than continuing to hang them. Towels, bed sheets, and thick clothing are harder to dry and should not be put away in closets while still damp. Stay hydrated during the summer Humidity makes sweat evaporate less easily, but the body can still lose a significant amount of water. Don't wait until you're very thirsty to drink water when you're out. If you're outdoors for extended periods, take breaks and avoid the hottest hours between noon and afternoon. If you experience dizziness, nausea, unusual fatigue, or confusion, seek a cool place to rest immediately and get help. Taiwan's summer humidity primarily comes from its island environment, moisture brought by monsoons, and the difficulty of sweat evaporation in high temperatures. It might be hard to adapt at first, but by preparing rain gear, maintaining room ventilation, using dehumidifying equipment appropriately, and paying attention to clothing and food storage, you can reduce the inconvenience caused by humidity. Spending summer in Taiwan is not just about learning to avoid the heat, but also about learning to live with humidity.
