Hong Kong’s climate is seasonal due to alternating wind direction between winter and summer. From September to December there are pleasant breezes, plenty of sunshine, and comfortable temperatures. January and February are cloudier, with occasional cold fronts followed by dry northerly winds. March and April are milder although there are occasional spells of high humidity. The period from April to August is hot and humid with occasional showers and thunderstorms. The months from July to September are most likely to be affected by severe weather phenomena such as tropical cyclones, monsoon troughs, and thunderstorms. There are on average about 30 tropical cyclones form in the western North Pacific or China Seas every year, and about half of them reach typhoon strength. Heavy rain from tropical cyclones may last for a few days and subsequent landslips and flooding sometimes cause considerably more damage than the winds (Hong Kong Observatory, 2018, November 30). Waterspouts and hailstorms occur infrequently, snow and tornadoes are rare, and there is a very small chance of major earthquakes (Hong Kong Observatory, 2018, November 27). Moreover, Hong Kong is not seriously affected by tsunami (Hong Kong Observatory, 2018, November 8).
