Geography dictates the start of hurricane season. Hurricane season in the Atlantic starts June 1. Hurricane season in the North Pacific begins May 15. According to the U.S. National Weather Service, 99 percent of all hurricanes occur within these periods.
Hurricanes in North America can strike at any point along the Atlantic seaboard of the United States and upwards into Canada. They can also strike anywhere along the coast of the Gulf of Mexico or at any of the islands in the Caribbean Sea. Hurricanes can strike any Pacific Ocean islands, including Hawaii. Only rarely do hurricanes strike the coast of Southern California.
