August gets roughly 1068% more precipitation than November — 432mm against 37mm. That difference, more than temperature, is what changes how a day here feels.
Daytime highs only move 14°C across the whole year (18–32°C), so timing matters far less here than rainfall does.
June gives you 13.4 hours of daylight against just 10.6 in December — a 3-hour difference in how much you can actually fit into a day.
December is the driest month at 27mm across roughly 2 wet days, while August peaks at 432mm.
December is almost as good as November, but usually quieter and cheaper. If your dates are flexible, it is the easier trip.
Hong Kong changes character completely through the year — November and August are effectively two different destinations. Pick the month that matches what you want to do, not the highest-rated one.
Ratings compare months within Hong Kong, not against destinations worldwide: five stars means the best time to be here, not that Hong Kong beats anywhere else. Tags describe what the conditions actually suit.

Each month in Hong Kong is described from long-run climate normals and then rated relative to the other eleven months in the same city. A five-star January in a cold destination means January is one of the best times to be there — not that it beats a Mediterranean summer.
| Factor | Weight | What it measures |
|---|---|---|
| Temperature | Described | Average daytime high and overnight low for the month, shown as measured rather than judged. |
| Precipitation | Described | Monthly millimetres and wet-day count, labelled as snow or rain/snow where temperatures make that the likely phase. |
| Sunshine & daylight | Described | Average daily sunshine hours and astronomical daylight length at mid-month, from the city’s latitude. |
| “Best for” tags | Derived | Applied only when the conditions genuinely support the activity — snow depth-friendly cold for skiing, 13–24°C and low rain risk for hiking, dark evenings at high latitude for aurora. A month with few strong use cases gets fewer tags rather than padded ones. |
| Star rating | Relative | Ranks the month against the other eleven months in the same city. Never a comparison between cities. |
Figures are long-run climate averages, not a forecast for a specific year. Where a month lacks sourced rainfall or humidity, the value is modelled from temperature range and rain frequency.
November is the best all-round month in Hong Kong: 23°C highs, 37mm of precipitation and 10.9 hours of daylight, which suits hiking, cycling and reliable sunshine. The strongest three-month window is November to January.
August — 32°C highs, 432mm of precipitation over roughly 26 days and 12.8 hours of daylight. It is the cheapest and least crowded time to go, and it still works for green season and quiet and local.
December is the driest month at 27mm over about 2 rain days, against 432mm in August. Across the year Hong Kong records around 2382mm.
Yes, but the months are genuinely different trips. November suits hiking, cycling and reliable sunshine, while August suits green season and quiet and local. Pick the month that matches what you want to do.
Daylight ranges from 10.6 hours in December to 13.4 hours in June, calculated from the city's latitude.
