This is the season when most lightning storms happen (and explain why...).
What is summer? Lightning storms happen in summer because the humid air is a poor conductor... this causes an electric charge to be built in the cloud, and the negative charge in the clouds draws the protons to the surface in the earth and the electrons move toward the earth.
