Cantonese Dictionary Vol. 73: 10 Cantonese Words for Weather, Rainstorms & Sweltering Heat Every Hong Konger Knows by Heart

Ask any Hong Konger what shapes daily life more than salary or rent and the honest answer is the weather. Between May and October the city runs on a rolling calendar of typhoon signals, black-rainstorm warnings, and a humidity so thick your shirt sticks to you the moment you walk to the MTR. This is Volume 73 of our Cantonese dictionary — ten weather words that every real Cantonese speaker in Hong Kong, Guangzhou, or the diaspora reaches for on autopilot. Miss these and you'll always sound like a tourist reading a forecast.

The Ten Weather Words

1. 打風

daa2 fung1 — Jyutping romanisation

Meaning: A typhoon is coming, or a typhoon signal is up.

Explanation: Literally "strike wind." It covers both the storm itself and the anticipation — the tape on windows, the extra bag of instant noodles, the group chat asking whether tomorrow is a work-from-home day. When someone says 打風呀, half the city is already checking the Observatory app.

In real life: 聽日打風，返唔返工呀？— "There's a typhoon tomorrow, are we going to work or not?"

2. 十號風球

sap6 hou6 fung1 kau4 — Jyutping romanisation

Meaning: Signal No. 10 — the highest typhoon warning in Hong Kong.

Explanation: The whole city stops. Offices close, MTR stations shutter, and the sound of loose signboards banging against concrete becomes the soundtrack. Hearing 十號風球掛起 gives millennial Hong Kongers the same rush their parents felt: a rare day of forced stillness.

In real life: 頭先掛咗十號風球，出面千祈唔好行呀。— "They just hoisted Signal 10, do not go outside."

3. 黑雨

hak1 jyu5 — Jyutping romanisation

Meaning: The Black Rainstorm Warning — the top level of Hong Kong's rainstorm signals.

Explanation: Short for 黑色暴雨警告. When the black signal is up, drains overflow, the underpasses become rivers, and schools stay shut. The three-tier amber–red–black system is so embedded in local life that Hong Kongers use the colour names as adjectives.

In real life: 仲落黑雨呀，遲啲先出去啦。— "It's still under a black rain warning, wait a bit before going out."

4. 落狗屎

lok6 gau2 si2 — Jyutping romanisation

Meaning: Raining absolutely torrentially — the Cantonese equivalent of "cats and dogs."

Explanation: Literally "dropping dog poop." No one is being polite when they use this one. It's earthy, funny, and reserved for the kind of rain where your umbrella surrenders in the first three seconds. A perfect example of the Cantonese talent for turning bodily-fluid metaphors into weather reports.

In real life: 出面落狗屎呀，你唔好出去啦！— "It's pissing down outside, don't go out!"

Heat, Humidity, and the Language of Suffering

Six months of the year, Hong Kong is a slow-cooking sauna. Air-con is a class marker, mothers order sons to change wet shirts, and every family kitchen keeps at least one pot of cooling herbal tea. If you are learning Cantonese and want to talk like a local about the heat, these next five words are non-negotiable — and one of them, 熱氣, is basically a whole philosophy of the body. If you want to wear that philosophy, we made a 熱氣 Yeet Hay embroidered heavyweight T-shirt that any auntie will understand instantly.

5. 熱死人

jit6 sei2 jan4 — Jyutping romanisation

Meaning: Hot enough to kill you — unbearably hot.

Explanation: The Cantonese love a good hyperbole. 死 (die) is used as an intensifier constantly — 悶死人, 嘈死人, 熱死人. It is dramatic, cathartic, and only mildly literal. If someone doesn't say this at least twice in July, you should check they're still breathing.

In real life: 今日真係熱死人，開冷氣啦！— "Today is literally killer hot, turn on the AC!"

6. 翳焗

ai3 guk6 — Jyutping romanisation

Meaning: Oppressively humid and stuffy — the air feels trapped, thick, and heavy.

Explanation: This is the specific feeling of a Hong Kong summer afternoon just before a rainstorm breaks. English has no equivalent single word — "muggy" is close but too light. 翳焗 is the atmospheric pressure sitting on your chest, the ceiling fan barely helping.

In real life: 今日好翳焗，好似要落雨。— "It's so stuffy and humid today, feels like it's going to rain."

7. 潮濕

ciu4 sap1 — Jyutping romanisation

Meaning: Damp, humid — the everyday word for the moisture level Hong Kong lives in.

Explanation: If 翳焗 is the acute suffering, 潮濕 is the chronic condition. It's what a Cantonese mum blames when the laundry won't dry, when the biscuits go soft, when your knees start aching. It's also the reason every Hong Kong home has a dehumidifier running from March to August.

In real life: 香港啲天氣真係好潮濕，衫都晾唔乾。— "Hong Kong's weather is really damp, even the clothes won't dry."

8. 回南天

wui4 naam4 tin1 — Jyutping romanisation

Meaning: The spring "return of the south wind" — warm, moisture-laden air that condenses on every cold surface in your flat.

Explanation: This is one of the most Cantonese words on the list because it names a phenomenon almost unique to Guangdong and Hong Kong. Walls sweat. Marble floors become skating rinks. Mirrors fog up permanently. Real ones know to close every window and run the aircon on dry mode.

In real life: 回南天嚟啦，記得抹地呀，好易跣親。— "The wui naam tin has arrived, remember to mop the floor, it's slippery."

9. 涼浸浸

loeng4 zam3 zam3 — Jyutping romanisation

Meaning: Deliciously cool, with a slight chill that soaks into you.

Explanation: Cantonese loves reduplicated adjectives like 浸浸 to add texture. This is the very specific relief of stepping into an air-conditioned mall after 40 minutes on a sweaty MTR platform, or walking outside on the first November morning when the summer finally breaks. It's a physical exhale.

In real life: 出面涼浸浸，好舒服呀！— "It's beautifully cool outside, so comfortable!"

10. 曬到甩皮

saai3 dou3 lat1 pei4 — Jyutping romanisation

Meaning: Sunburnt to the point of peeling — literally "grilled until the skin comes off."

Explanation: Every diaspora auntie has warned some poor cousin about this on a Sai Kung boat trip. It's also used loosely — anyone stepping outside without SPF in August risks 曬到甩皮 by dinner. And of course, at the family table it comes with the classic mum reminder about wearing more layers, which is why the 著多件衫 Wear More Layers hoodie is basically your mum in fabric form.

In real life: 你尋日冇搽防曬呀？曬到甩皮啦！— "Did you skip sunscreen yesterday? You're peeling!"

Weather Is Cantonese Small Talk

Notice a pattern? Cantonese weather vocabulary is physical, dramatic, and often funny. It's the same instinct that gives us untranslatable words like 得閒 — Cantonese speakers refuse to talk around a feeling when they can just name it directly. That's why 熱氣, 潮濕, and 翳焗 are still doing daily work in Cantonese while the English "muggy" barely gets a run.

If you grew up in Hong Kong, these words are muscle memory. If you're diaspora, they're the fastest way to sound like you actually spent a summer at Grandma's flat in Sham Shui Po. Bookmark this one — you'll use every word on the list before September ends.

And when a co-worker says 求其啦 ("whatever") about the black rain warning, you know they've stopped caring about staying dry — that phrase is on our 求其 Whatevs oversized tee for exactly that mood.
