下雪了。

You use this phrase exactly like a complete sentence. You don't need a subject like 'it' in English. Just say 下雪了. If you want to be specific, you can add words like 外面 (outside). For example, 外面下雪了. It works as a standalone exclamation or as part of a longer story.

Use it the second you see those white flakes. Text it to your group chat. Whisper it during a boring meeting while looking out the window. It is perfect for small talk with neighbors. You can also use it to explain why you are late. 'Sorry, 下雪了, the traffic is terrible!' It is a universal conversation starter in cold climates.

Don't use this if the snow is already deep on the ground but stopped falling. In that case, you'd say 有积雪 (there is accumulated snow). Also, avoid using it for light frost or hail. If it is just a tiny bit of snow, you might add 一点点 (a little bit). Don't say it in the middle of summer unless you're in a movie or very confused.

In China, the first snow of the year is a big deal. People love posting photos of it on WeChat Moments. In Beijing, everyone rushes to the Forbidden City to see the red walls against white snow. There is a saying: 'A fall of seasonable snow gives promise of a fruitful year.' Snow isn't just weather; it is a blessing for the coming harvest. It brings a sense of peace and poetic beauty to the busy city life.

You will hear people say 下大雪了 when it is a heavy blizzard. If it is just starting, they might say 开始下雪了. In the south of China, where snow is rare, you'll hear much more screaming and excitement! People might shout 竟然下雪了! which means 'It's actually snowing!' as if a miracle just happened. If you are cold, follow it up with 太冷了 (too cold).
