Although Hong Kong is subtropical, it has four distinct seasons. Fall—September through November—is the best time to visit, when temperatures are typically in the 70s, and days are sunny and bright. Look for shoulder season deals in late September. China’s National Day in October brings an influx of tourists from the mainland, as well as a spike in hotel occupancy and rates.
Winter—December through February—also provides a pleasant environment, with cooler temperatures in the 60s and little chance of heavy rain. It can get quite chilly, though, so pack a sweater and light jacket for those gloomier days. Chinese New Year, which falls in January or February, is a huge celebration in Hong Kong. It’s a marvelous spectacle, but you’ll pay a high price to enjoy it.
The spring months of March to May are unpredictable, and temperatures begin to rise from the 60s to the 80s with frequent rains. Nevertheless, shoulder-season deals can be had in March, and events are plentiful. The Hong Kong Rugby Sevens in late March attracts fans from around Asia and Europe, making it hard to find reasonably priced accommodation on these dates. Late March/early April features the high-profile Hong Kong International Film Festival. Those after a more local experience will enjoy the Cheung Chau Bun Festival, which takes place in April or May. A procession featuring costumed children on stilts makes its way through the streets, and towers built of buns stand in front of the local temple.
Summer—June through August—can be miserable, with temperatures in the 80s and humidity to match. Summer showers are frequent but don’t last long. Typhoons can hit Hong Kong at any time during spring or summer, bringing torrential rains.
