  abstract = {{D}uring the last 4 decades punctual occurrences of extreme ocean temperatures, known as marine heatwaves ({MHW}s), have been regularly disrupting the coastal ecosystem of the {P}eru-{C}hile eastern boundary upwelling system. {I}n fact, this coastal system and biodiversity hot-spot is regularly impacted by {E}l {N}ino events, whose variability has been related to the longest and most intense {MHW}s in the world ocean. {H}owever the intensively studied {E}l {N}inos tend to overshadow the {MHW}s of shorter duration that are significantly more common in the region. {U}sing sea surface temperature data from 1982 to 2019 we investigate the characteristics and evolution of {MHW}s, distinguishing events by duration. {R}esults show that long duration {MHW}s (> 100 days) preferentially affect the coastal domain north of 15 degrees {S} and have decreased in both occurrence and intensity in the last four decades. {O}n the other hand, shorter events, which represent more than 90% of all the observed {MHW}s, are more common south of 15 degrees {S} and show an increase in their thermal impact as well as on the number of affected days, particularly those spanning 30-100 days. {W}e also show that long duration {MHW}s variability in the coastal domain is well correlated with the remote equatorial variability while the onset of short events (< 10 days) generally goes along with a relaxation of the local coastal wind.},
