बहुत गरमी है

Use it as a standalone sentence. You don't need a subject like "the weather." Just say bahut garmi hai while wiping your forehead. You can add Aaj (today) at the start: Aaj bahut garmi hai. If you want to emphasize it, stretch the word bahut to bauhaaaaat. It makes you sound like a local who is truly suffering with everyone else.

You can use this everywhere. Use it when walking into an air-conditioned office. Use it while waiting for a bus. Use it when texting a friend to explain why you're late. It is a perfect conversation starter with strangers. If you see someone fanning themselves with a newspaper, say this. They will definitely agree with you. It creates an instant bond over shared discomfort.

Don't use this to describe food. For hot tea or spicy curry, use garam. Garmi is specifically for weather or the sensation of heat. Also, don't use it if the temperature is pleasant. Indians have a high heat tolerance. If it's 25°C (77°F), saying bahut garmi hai might get you some confused looks. Save it for when the asphalt is actually melting.

In India, the heat isn't just weather; it's a season of life. It dictates what you eat, when you go out, and your mood. The phrase is often followed by a deep sigh. There is a cultural obsession with 'Loo' (the hot summer wind). When you say bahut garmi hai, you are participating in a national ritual of collective venting. It's the verbal equivalent of seeking shade under a mango tree.

You might hear Badi garmi hai which means the same thing. In Mumbai, people might say Kaafi garmi hai. If it's humid, they say Umas hai. But Bahut garmi hai remains the gold standard. If you want to be dramatic, say Garmi se bura haal hai. This means "The heat has made my condition miserable." It’s a bit dramatic, but very authentic!
