Hong Kong’s weather is distinctly divided into seasons. Spring is pleasant and foggy, summer is hot and rainy, autumn is cool and windy and the winter is cold but sunny. Temperatures range from a low of 10C to 30 C, averaging 20 C annually. Days with higher than 30 C temperatures number 100+; less than 10 C number about 30. Average humidity is 81.5%.
Spring (March – May): Nicely mild and temperate at first, but ends with the wettest weather of the year. This temperamental time can deliver clear skies and black thunderstorms within hours. Bring those umbrellas everywhere. Slightly, an off season!
Summers (June – August): Hot, wet and humid. Visitors beware: this is typhoon season! There are bound to be some truly impressive storms. Shirts and shorts are sensible, but you might want to consider long sleeves if you sunburn easily. Swimming is everyone’s favorite activity during this time. Perfect for families visiting Hong Kong!
Autumn (September – November): The season has the best balance in daily temperatures and is considered a peak season. T-shirts and shorts will suit the days you stroll around, but pack light sweaters for the evenings. Certainly, this is the best time to visit Hong Kong.
Winters (December – February): Winters are mild, but can be frosty on rare occasions. Crisp air and clear skies make for a pleasant contrast to summer. Coats, sweaters and light jackets are recommended.
Best time to visit Hong Kong is September to November end or early December. This is peak season for tourists as well.
