Rob Marciano

Robert Mark Marciano (born June 25, 1968) is an American journalist and meteorologist who was employed by ABC News. Marciano provided forecasts for the weekend editions of Good Morning America, a position Ginger Zee vacated when she was chosen to succeed Sam Champion on the daily editions of GMA.

Marciano first gained prominence as a meteorologist and occasional reporter and substitute anchor for CNN Worldwide in their Atlanta headquarters.

Prior to his employment by ABC, Marciano was most recently employed by Entertainment Tonight, where he co-anchored the nightly thirty-minute edition of the program as well as the sixty-minute weekend edition. He left ET in late August 2014 after twenty months to take his current position with ABC.

On April 30, 2024, Marciano's employment at ABC News ended after what news reports called "anger management issues" and "allegedly inappropriate behaviors."

Marciano was born in Glenville, Connecticut, and received a bachelor's degree in meteorology from Cornell University. He holds the American Meteorological Society Seal of Approval and is a Certified Broadcast Meteorologist (CBM). He is of Italian and German ancestry.

Before joining CNN in May 2003, he served as chief meteorologist for KATU-TV and 750 KXL News Radio in Portland, Oregon. From 1994 to 1997, he worked as morning and then chief meteorologist for KPLC-TV in Lake Charles, Louisiana and later served as a weather anchor for WVIT Connecticut News 30 in West Hartford, Connecticut.

On November 12, 2012, Marciano was announced as a new co-anchor for Entertainment Tonight, which he would begin doing in January 2013. The choice followed a long search period for a new co-anchor to host the program with Nancy O'Dell, a search that began when Mark Steines left the series after eight years as the primary co-anchor. Marciano bid farewell to CNN viewers on Early Start and Starting Point on December 21, 2012.

On July 19, 2014, ABC News announced that Marciano would become the network's senior meteorologist. He has since joined Good Morning America Weekend and reports on the latest weather headlines throughout the week as well as partners with Ginger Zee and the Extreme Weather Team for weather coverage across all ABC News broadcasts and platforms. His final co-hosting of Entertainment Tonight was Wednesday, August 27, 2014 and he debuted on GMA Saturday, September 6, 2014.

Marciano is an avid outdoorsman and major sports fan. He married real estate mogul, Eryn, in 2010. However, they separated in 2021 and instigated divorce proceedings in 2022. Together they have one daughter, Madelynn, and one son, Mason.
