What is the weather like in Hong Kong in 2026?

The Hong Kong Observatory (HKO) treats meteorological summer as June to August and winter as December to February. November and December often bring pleasant breezes, sunshine, and the temperatures many residents call the best of the year. January and February turn cloudier, with occasional cold fronts and dry northerly winds.

March and April warm up but can feel humid, with drizzle or fog that sometimes disrupts air traffic and ferries. May to August are hot and humid, with morning showers and thunderstorms common; afternoons often climb above 31°C while nights stay sticky around the mid-20s. A finer, drier spell can appear in July for a week or longer in some years. Cooler detail: Does Hong Kong get cold in winter?.

Most of the year's rain falls between May and September, with June and August often among the wettest months and January and December among the driest. Tropical cyclones may affect Hong Kong from May to November; July to September is the most likely window. When a storm nears, winds rise, rain can last days, and landslips or flooding can matter as much as wind. Rain and signal life: Does it rain a lot in Hong Kong?.

Expect summer air-conditioning to dominate electricity more than heating. Light waterproof layers beat a single winter coat for most of the year, with a warmer layer for cold-front mornings. Typhoon days can close offices and cancel outdoor plans; build buffer into ferry-dependent Discovery Bay or outlying-island routines. Utilities angle: Utilities, internet and transport.
