They ran experiments that steam-distilled rocks to reveal a yellow oil that was trapped in the rocks and soil, which accounts for the distinctive smell.

The scent is usually the strongest as it begins to rain or just before it starts.

According to the National Weather Service;

petrichor can be most noticeable when it rains after a long dry spell on a hot day. That's because the drier the soil, the greater the buildup of plant oils and bacteria spores on the ground. Now I have a valid answer to my question.
