No, hurricanes don’t form on the equator because there is no coriolis force. This force causes the spin of air as it flows into an updraft of air making showers. When you look at a drain, water spins down because of the coriolis force. This force is zero at the equator and grows the farther from the equator you go. The Northern Hemisphere of the Earth spins in one direction, while the Southern Hemisphere spins in the opposite direction. Most hurricanes need to be about 10 degrees North latitude or higher to have enough spin to form. - Phillip Williams
