Hong Kong weather is not a background — it's a conversation. Between Amah Rock summers, plum-rain damp, sudden T8 typhoons and skies the colour of old dumpling wrappers, Cantonese speakers have built a rich, brutally honest vocabulary for the sky. In this volume of the Cantonese Dictionary, we round up ten weather and sky words that a Hong Konger will use before their first cup of milk tea — from complaining about the humidity to declaring, with quiet joy, that a typhoon is coming and the office is closed.
These are conversational words. You won't hear them in a TVB weather forecast, but you will hear them in a taxi, at yum cha, or in the group chat that decides whether Sunday hiking is still on. Wear them right and you'll sound less like a textbook and more like someone raised under an umbrella at a bus stop in Mong Kok — the same everyday register that inspires our Cantonese slang streetwear collection.
10 Cantonese weather words that shape a Hong Kong day
1. 落雨
lok6 jyu5 — Jyutping romanisation
Meaning: It's raining. Literally "falling rain."
Explanation: The basic verb-object phrase every child learns. Cantonese doesn't say "rain" as a verb the way English does — it always splits into 落 (fall) + 雨 (rain). If you say "it rains" as one word, you sound like a textbook.
2. 打風
daa2 fung1 — Jyutping romanisation
Meaning: A typhoon is coming / there's a typhoon. Literally "hitting wind."
Explanation: In Hong Kong this word triggers a full protocol: taping the windows, buying bread and instant noodles, and quietly hoping the Observatory raises the T8 signal so the office closes. Meteorologically it means anything above T3.
3. 好焗
hou2 guk6 — Jyutping romanisation
Meaning: Stiflingly hot and airless. Not just hot — stuffy, closed-in, like a lidded pot.
Explanation: 焗 is the same character used for "baked" or "braised in a covered pot." Applied to weather, it perfectly captures a Hong Kong summer afternoon when the air conditioning breaks on the MTR. English "hot" doesn't come close.
4. 潮濕
ciu4 sap1 — Jyutping romanisation
Meaning: Humid, damp. The everyday word for high humidity.
Explanation: In February and March, when the plum-rain fog rolls up from the South China Sea and floors sweat and walls drip, this word gets a lot of use. Hong Kongers link it directly to how your body feels — sluggish, heavy, in need of soup.
5. 好凍
hou2 dung3 — Jyutping romanisation
Meaning: Very cold. But contextually: a Hong Kong "cold" is anything under 15°C.
Explanation: Cantonese speakers use 凍 for both cold weather and cold drinks. A 12°C morning in January will have every mum reminding her kid to "wear more layers" — the exact sentiment on our 著多件衫 Wear More Layers oversized tee.
6. 灰濛濛
fui1 mung4 mung4 — Jyutping romanisation
Meaning: Grey and hazy — a sky washed of colour.
Explanation: An ABB-style descriptive word (see our Vol. 94 ABB reduplicated words). Used for pollution haze, plum-rain fog, or a cloudy typhoon-adjacent day. The doubled 濛濛 gives it a soft, dreamy quality — the sky isn't just grey, it's fuzzy at the edges.
7. 出太陽
ceot1 taai3 joeng4 — Jyutping romanisation
Meaning: The sun is out. Literally "the sun has come out."
Explanation: A small phrase with a huge emotional payload after a week of drizzle. Mums use it to hurry laundry onto bamboo poles; office workers use it to justify skipping lunch and walking somewhere with a view.
8. 熱到爆
jit6 dou3 baau3 — Jyutping romanisation
Meaning: Hot to the point of exploding. "Hot AF" in Cantonese.
Explanation: The 到爆 pattern ("to the point of bursting") is a Cantonese intensifier that gets slapped on almost any adjective. When July hits 36°C and the pavement steams, this is the only phrase that fits — much like the "mirror-breaking beautiful" of our 靚爆鏡 Mirror Breaks sweatshirt.
9. 天陰
tin1 jam1 — Jyutping romanisation
Meaning: Overcast. Literally "sky yin" — sky in its shadow/cloudy state.
Explanation: Neat compound word using the yin-yang framework: 陽 (yang) for sunny, 陰 (yin) for cloudy. Weather forecasts use it constantly, and older aunties will pair it with an ominous "going to rain soon" prediction that turns out to be correct 80% of the time.
10. 起霧
hei2 mou6 — Jyutping romanisation
Meaning: Fog rising. Literally "raising fog."
Explanation: Peaks like The Peak and Tai Mo Shan disappear behind curtains of low cloud a few times a year. Locals use 起霧 for that moment when the ferry pulls out of Central and Kowloon starts vanishing — that whole 廣東仔 identity is something we wear on our chest, fog and all.
Why Hong Kongers have so many weather words
South China's climate throws six real seasons at you, not four: dry cool winter, damp foggy spring, humid pre-monsoon, wet plum-rain, blazing typhoon summer, and clear-crisp autumn. Cantonese vocabulary evolved to match — with fine-grained distinctions between "just muggy" (焗), "damp" (潮濕), and "grey haze" (灰濛濛). Even the tropical-cyclone signals from the Hong Kong Observatory are baked into daily speech: T3, T8, T10 are shorthand every child understands.
Learning these words isn't just about vocabulary — it's about understanding how Cantonese speakers experience the world. The sky is never neutral. It's an antagonist, a friend, an excuse. It gets talked to.
