Hong Kong has roughly four moods: too hot, too humid, too wet, or too typhoon. The city sits on the South China coast, so the weather is a daily conversation starter, a reason to stay in bed, and a built-in excuse for being late. If you learn 10 Cantonese weather words, you unlock half the small talk in a Hong Kong mum's phone call and 100% of the WhatsApp group chat on a Signal 8 morning.
This volume covers the words Hong Kongers mutter from the first blast of August humidity to the last cold snap in February. Some are literal. Some are colourful. All of them are useful.
The 10 words
1. 熱
jit6 — Jyutping romanisation
Meaning: Hot.
Explanation: The baseline word, but Cantonese speakers rarely leave it alone. You'll hear 好熱 (very hot), 熱到死 (hot to death), or doubled up as 熱辣辣 for food that is scalding on the tongue. In August Hong Kong, "熱" is a complete weather forecast on its own.
2. 凍
dung3 — Jyutping romanisation
Meaning: Cold.
Explanation: Hong Kong rarely dips below 10°C, but when it does, Cantonese mums swing into action with soup, extra layers, and a weather report every half hour. 凍 is also what you say about iced drinks (凍奶茶 — iced milk tea).
3. 翳焗
ai3 guk6 — Jyutping romanisation
Meaning: Sticky, muggy, oppressively humid.
Explanation: English doesn't quite have a word for this. 翳焗 is that pre-thunderstorm feeling when the air is still, your shirt sticks to your back, and the clouds are heavy but refuse to break. It describes the humidity that makes you want to lie flat on the tiled kitchen floor.
4. 落雨
lok6 jyu5 — Jyutping romanisation
Meaning: It's raining. Literally "falling rain".
Explanation: Standard Mandarin uses 下雨 (xià yǔ), but Cantonese keeps the older verb 落 — the rain "falls down". Hong Kongers obsess over the rainfall warnings: Amber, Red, Black. A Black Rain Warning means the city can legally shut down.
The muggy-rainy pair above is Hong Kong's spring and summer in two words. A hot afternoon turns 翳焗, then 落雨, then — if you're unlucky — the weather radio buzzes and you hear the next word on the list.
5. 打風
daa2 fung1 — Jyutping romanisation
Meaning: A typhoon is hitting. Literally "hit wind".
Explanation: From June to October, Hong Kongers obsess over whether the city will 打風. If it does, the kids pray for a Signal 8 so school closes. Adults quietly check whether work closes too. The Hong Kong Observatory has run the typhoon warning system since 1884.
6. 掛八號
gwaa3 baat3 hou6 — Jyutping romanisation
Meaning: To hoist Typhoon Signal No. 8.
Explanation: Signal 8 is the magic number: offices, schools, and the stock exchange shut down. The verb 掛 ("to hang") comes from the pre-radar days when the Observatory literally hung a shape on a mast to show the signal strength. Hong Kongers still say "掛" even though no one is hanging anything today.
If you want to go deeper on Signal 8 and the whole 1884 Cantonese weather code, we wrote a full history of the Hong Kong typhoon signal system that explains why the city still legally stops at that one number.
7. 回南
wui4 naam4 — Jyutping romanisation
Meaning: The spring return of warm, humid southerly winds that fog up every window in Hong Kong.
Explanation: After the dry winter, when warm sea air sweeps back onto the cold land, condensation forms on every tile wall, every mirror, and every bathroom floor. 回南天 is why Hong Kong flats smell faintly damp in March. There's no polite English translation for the phenomenon.
8. 行雷
haang4 leoi4 — Jyutping romanisation
Meaning: Thunder. Literally "walking thunder" — the thunder walks across the sky.
Explanation: A classic Cantonese compound where the verb 行 (walk) gives thunder a slow, rolling character. Pair it with 閃電 (lightning) and you have the full summer afternoon soundtrack over Kowloon.
9. 冷親
laang5 can1 — Jyutping romanisation
Meaning: To catch a chill — the cold has literally touched you.
Explanation: The suffix 親 means something has affected you. 冷親 is what a Hong Kong mum fears the moment she sees your bare arms. In Cantonese folk wisdom, 冷親 isn't the same as catching a virus — it's a specific kind of cold-induced body imbalance that only hot ginger soup can fix.
10. 乾爽
gon1 song2 — Jyutping romanisation
Meaning: Dry and crisp — the rare, delicious kind of weather.
Explanation: After months of mugginess, a 乾爽 autumn day in Hong Kong is a celebration. The humidity drops, the sky clears, and the whole city suddenly wants to hike or picnic. Weather forecasters use it, Hong Kong mums use it, and your laundry finally dries in under 24 hours.
Why Hong Kong talks about the weather this much
Partly because the weather is genuinely extreme — a city that sits just south of the Tropic of Cancer has to deal with monsoons, humidity, and typhoons that reshape the skyline. Partly because the Cantonese language itself has 150 years of coastal vocabulary built in. A fishing village that became a port city, a port city that became a global hub, kept inventing weather words along the way.
The result is a vocabulary that's more precise than English about damp air, more superstitious about chills, and more cinematic about typhoons. When a Hong Kong mum calls to ask if you've eaten, the follow-up is almost always a weather report. You can read more about those classic Cantonese mum phrases from a previous volume.
