Is it normal to smell rain before it comes?
Yep.Totally normal
Yes. Lots of people notice a distinctive earthy smell before or as rain arrives, thanks to compounds released from soil and plants.
That earthy, fresh smell is often called petrichor. When rain is on the way, moisture and changing air can lift scent compounds from the ground and plants, making them easier to notice. Some people also pick up the sharp smell of ozone ahead of a storm.
Not everyone detects it, but noticing it is normal—and it can make you feel like you have a tiny weather forecast built into your nose.
