When do hurricanes form?

Hurricanes form in the tropics, over warm ocean water (over 80ºF or 27ºC) and at latitudes between 8° and 20°, Hurricanes form mostly from June through November (hurricane season). These powerful storms are fueled by the heat energy that is released when water vapor condenses (turns into liquid water -- rain).
