The humidity in Hong Kong can really ruin your vacation and when things really get hot a short walk to the shops can leave your shirt looking like a dish towel after a spin in the washing machine. Below are the month-by-month average humidity figures for Hong Kong, but before reading them it’s worth reading the short introduction, explaining what the readings actually mean.
Humidity is what makes the air feel like a sauna, filled with damp steam. More scientifically, it is actually the measurement of water vapor in the air, with a maximum of 100%.
What does this mean for you? Well, the higher the humidity, the harder it is for sweat to evaporate, which means that your body temperature rises and makes you sweat more. This is only a problem in high temperature, which makes you sweat in the first place; But since high humidity in Hong Kong often accompanies high temperatures, it can mean that more than two minutes on the street will make you sweat, often profusely. Fortunately, buildings, transportation, and even some walkways are air-conditioned, but it requires staying indoors.
