Historical index of activity during the East Pacific hurricane season (as a percentage of the mean)

After the National Hurricane Center is the Pacific hurricane season between May 15 and September 30, the Central Pacific , it is between 1 June and 30 September there at this time good conditions for the formation of tropical storms are present . The ocean is warm enough, there is hardly any wind shear and the humidity is high enough. All storms that form north of the equator and east of 180 ° W count as Pacific hurricane season. Storms that form west of 180 ° W are called typhoons and are part of the Pacific typhoon season . Statistically speaking, the area is the second most active area for tropical storms to develop, yet they hardly threaten land, as they mostly move out into the open ocean. The hurricanes that hit the countryside often have an impact on western Mexico and less often on California or the northwestern part of Central America. In the database there is no storm that reached the mainland of California, but a storm is said to have caused winds of 65 knots in San Diego in 1885. The exact course of this small hurricane is not known.
