Vietnamese is full of colourful idioms, and many of them revolve around the weather. Whether you’re dodging monsoons or sweating through a heatwave, these expressions will make your speech more vivid and authentic. Here’s a rundown of some of the most common - and entertaining - weather-related idioms.
1. “Nắng như đổ lửa” (Hot as pouring fire)
Nắng như đổ lửa
/naŋ˧˥ ɲɨ˧˧ ɗo˧˩ lɨə˧˩/“Hot as pouring fire”
You’ll hear this one a lot in the summer, especially in cities like Hanoi or Ho Chi Minh City, where the humidity cranks up the misery. If someone says, “Hôm nay nắng như đổ lửa,” they’re not exaggerating - they’re just Vietnamese.
2. “Mưa như trút nước” (Rain like pouring water)
Mưa như trút nước
/mɨə˧˧ ɲɨ˧˧ ʈut˧˥ nɨək˧˥/“Rain like pouring water”
Vietnam’s rainy season is no joke. If you’re caught without an umbrella and someone shouts, “Mưa như trút nước rồi!”, they’re basically telling you to run for cover before you turn into a drowned rat.
3. “Gió heo may” (Autumn wind)
Gió heo may
/zɔ˧˥ hɛw˧˧ maj˧˧/“Autumn wind”
Northern Vietnam actually has seasons, and “gió heo may” is how locals describe that first hint of autumn chill. If you want to sound like a poet, drop this into conversation when the leaves start turning.
4. “Nóng như lửa đốt” (Hot as burning fire)
Nóng như lửa đốt
/nɔŋ˧˥ ɲɨ˧˧ lɨə˧˩ ɗot˧˥/“Hot as burning fire”
Use this when the air conditioning breaks, or when you’re stuck in traffic at noon. Bonus points if you fan yourself dramatically while saying it.
5. “Trời đất ơi” (Oh heavens)
Trời đất ơi
[t͡ɕəːj˨˩]“Oh heavens”
When the umpteenth downpour ruins your plans, or the heatwave just won’t quit, this is the phrase you yell at the sky. It’s cathartic.
Why Bother Learning These?
Weather small talk is universal. Mastering these idioms means you’ll never be stuck for conversation - whether you’re chatting with a street vendor or bonding with colleagues over the misery of a sudden downpour. Plus, they’re just fun to say.
