No hurricanes hit the U.S. for the 1st time since 2015. Why?

The 2025 Atlantic hurricane season proved to be consequential, even though no hurricanes made landfall in the U.S for the first time since 2015.
Three Category 5 hurricanes formed during this past hurricane season, tying for the second-most on record in the Atlantic basin. The only other season that saw more Category 5 storms was in 2005, when there were four Category 5 storms.
Last month, Hurricane Melissa became one of the most powerful hurricanes on record to make landfall in the Atlantic basin, ranking with Hurricane Dorian
