Heading to Hong Kong, or already there? Here’s what the next two weeks actually look like — heat, rain, UV, wind, and air — plus what to sort before you go. For official warnings, defer to the Hong Kong Observatory.
Live conditions & risk

Live weather, UV, air quality, and sea state from Open-Meteo · refreshes hourly. Categories use standard scales (WHO UV, EPA AQI, Beaufort, WMO sea state).
Your prep checklist
- See a travel clinic before you go — Hepatitis A and typhoid are the usual shots for Hong Kong.
- Pack a light rain shell and quick-dry layers; summer rainstorms hit suddenly.
- Pack reef-safe SPF 30–50, a hat, and sunglasses.
- Install the Hong Kong Observatory app to catch typhoon and rainstorm signals, and save emergency 999.
- Hiking? Plan routes with bail-out points, carry water, and skip trails in thunderstorms.
Location
Precautions before you go out
Apply broad-spectrum SPF 30–50 before you head out; reapply every 2 hours and after swimming. Water and sand reflect UV, so you burn faster near the coast.
Heat illness is a real risk on summer hikes. Hydrate, take shade breaks, and start early — teens overheat faster during exertion.
When the Observatory hoists signal T8 or above, or a Red/Black rainstorm, stay indoors and off trails and water — flash floods and landslips come fast.
Jellyfish turn up at beaches in summer. Swim at gazetted beaches with lifeguards; heed flags. If stung, leave the water, don’t rub, rinse with seawater, remove tentacles, and get first aid.
Trails can be steep and remote. Tell someone your route, carry water and a charged phone, and avoid exposed ridgelines in thunderstorms.
This guidance is written for ages 12 and up. Younger children burn and dehydrate faster, react more severely to stings and bites, and need closer, hands-on supervision. General information, not a substitute for local warnings or medical care.
Diseases, carriers & vaccinations
No malaria risk in Hong Kong.
- DengueAedes mosquitoes (bite by day)
Seasonal risk in summer and autumn. No vaccine in routine use — prevent bites.

- Hepatitis BConsider depending on activities and length of stay.
