A strong El Niño can last a year or more before conditions return to normal.it lasts more or less as long as it takes the interior-ocean waves to travel all the way over to the coast of Asia, get reflected, and travel back.
El Niño shows up annually in late December in the Pacific, traveling east and usually only lasting a few weeks or a little over a month. However, we hear about it every three to seven years when it lasts for many months; it has been known to last over a year. When the unusually warm water current lasts for this amount of time, it can create lots of flooding and heavy rainfall around the Pacific rim. In the last forty years, the worst long-lasting El Niño occurred from 1997-1998.
