Why the Odds Changed
Hong Kong is expected to record total rainfall between 220 and 230 millimeters in May 2026, in line with seasonal wet-weather patterns.
Recent Developments
Hong Kong is on course to see total precipitation of between 220 and 230 millimeters during May 2026, a level consistent with the city’s transition into the wetter early-summer months. The final figure will be based on daily rainfall data compiled by the Hong Kong Observatory for the period from May 1 to May 31.
May typically marks a notable increase in rainfall across the territory, with showers, thunderstorms and humid conditions becoming more frequent as the southwest monsoon begins to influence the region. A monthly total in the projected range would point to a wet but not exceptional month for Hong Kong, with rainfall distributed across periods of unsettled weather rather than driven by a single extreme event.
Authorities and residents are expected to continue monitoring daily forecasts as the month progresses, particularly during episodes of heavy showers that can affect transport, outdoor work and low-lying areas. The Hong Kong Observatory’s finalized rainfall records will provide the official monthly total after the close of May.
