Hong Kong is a year-round destination with the winters being rather mild and the summers hot and sticky. The best time of the year to be here is near the end of September to early December. The air is clear and the humidity drops off to about 70% from summer's rainy season of 80% or more. Summers can be very hot and the usual precautions are recommended.
One thing you might want to consider is a light pullover or windbreaker tucked in your bag for the powerful air-conditioning in many places (we're not complaining)! December and January see the lowest rainful and the lowest temperatures. By the spring, it's warming up and while it's a bit more humid and a little more rainy than the fall, it's still a good time to be here. Prepare for humid and you'll be pretty much ready for any type of Hong Kong weather.

Summer (June, July & August)
Hot and humid are the words here. This is Hong Kong's (and most of Southeast Asia's) rainy season, and can often extend well into September. Keep in mind that there are many very nice days in the rainy season -- it doesn't rain all day every day. Often, it will rain hard for an hour or two and then clear up for the rest of the day. Unfortunately, when it's not raining it's hot! Sunscreen, hats and even umbrellas (that's what the locals do) are used to keep off the sun. The rainy season can also mean typhoons, but Hong Kong has an excellent, modern advance warning system so not to worry.

Autumn (September, October & November)
This is the best time to be here weather wise. It's also a very popular season for trade shows, conventions, and exhibitions where the whole city can be booked up for several days. Because of this, hotel rates can be much higher during these periods. Please check with us in advance.

Winter (December, January & February)
