Hong Kong weather, explained

How to read the Hong Kong forecast

A good forecast is really three views at once. The current panel tells you what it feels like outside right now, which is what matters before you head out the door. The hourly strip is for planning the next part of your day: when the rain band arrives, when the wind picks up, when it is warm enough to walk. The seven-day outlook is for the week ahead, and it is most reliable in the first three or four days. Read it from the top down and you will almost always have what you need for Hong Kong.

Hong Kong weather and the coast

Hong Kong's weather is shaped by its coastal, subtropical setting. The surrounding sea keeps humidity high and softens the temperature swings you would see further inland. In summer the prevailing southerly and south-westerly winds carry warm, moist air off the water, feeding the afternoon showers and thunderstorms that build over the hills. This is also typhoon season, when tropical cyclones tracking across the South China Sea can bring sustained heavy rain and strong gusts. In winter a cooler, drier north-easterly monsoon takes over, delivering the clearest and most comfortable days of the year.

What the UV index means in Hong Kong

Hong Kong sits at a subtropical latitude of about 22 degrees north, which puts it in a UV band that surprises many visitors. On clear summer days the UV index regularly reaches 11 or above, meaning skin can burn in under ten minutes around midday. The index peaks at solar noon, not at the hottest part of the afternoon, so checking the number rather than judging by the temperature is the most reliable habit. Below 3 is low and you can be outside without extra protection. From 3 to 7 means sunscreen earns its keep. Above 8 means a hat, sunscreen and shade are all genuinely useful, not optional.
