A new “Bachelorette,” lots of reality programming and a big, global concert — summer TV has arrived. Here’s what to watch and what to avoid on television this week:
Monday: “The Bachelorette,” 7 p.m., ABC: Twenty-five guys compete. The grand prize? A woman!
“River Monsters,” 7 p.m., Animal Planet: Of course the Loch Ness monster is real. Who do you think came up with the idea to fake the moon landing? Season 5 concludes with this 2-hour episode.
“Mermaids: The Body Found,” 7 p.m., Discovery: Of course mermaids are real. Who do you think has been hiding Nessie?
“The Glades,” 8 p.m., A&E: Season 4 begins.
“Longmire,” 9 p.m., A&E: Season 2 kicks off with a hostage crisis.
Tuesday: “Extreme Weight Loss,” 7 p.m., ABC: The former “Extreme Makeover: Weight Loss Edition” sheds a few words from its title for its third season 3 premiere.
“In Performance at the White House,” 7 p.m., PBS: Carole King performs along with James Taylor, Billy Joel and others while nabbing the Gershwin Prize for Popular Song.
“Body of Proof,” 9 p.m., ABC: No need for an autopsy — low ratings are to blame for making tonight’s episode the series’ last.
Wednesday: “Melissa & Joey,” 7 p.m., ABC Family: Season 3 kicks off tonight.
“The American Baking Competition,” 7 p.m., CBS: Bakers face off, and the grand prize is a lot of dough.
“Love Thy Neighbor,” 8 p.m., OWN: Tyler Perry’s new sitcom premieres.
“Nova,” 8 p.m., PBS: Timely, back-to-back episodes explore the hunt for the Boston bombers and tornadoes in Oklahoma.
“Bomb Girls,” 8 p.m., Reelz: The Canadian series based on women in a World War II munitions factory turned out to be a dud. The final episode airs tonight.
“Psych,” 9 p.m., USA: Season 7 ends tonight.
Thursday: “Does Someone Have to Go?” 8 p.m., Fox: Turns out this reality program isn’t about drinking too much water before a super long road trip. I’m relieved.
Friday: “Treehouse Masters,” 9 p.m., Animal Planet: Tonight’s series premiere profiles a treetop spa in Texas. You’ll need that relaxation after climbing the ladder.
“America’s Book of Secrets,” 9 p.m., History 2: Of course Bigfoot is real. Somebody has to divert attention from the mermaids.
“Merlin,” 9 p.m., Syfy: The titular wizard fights to save Camelot and King Arthur in the series finale.
Saturday: “Celebrity Ghost Stories,” 8 p.m., Bio: “Cheers” star George Wendt talks about an encounter in a spooky cottage. When the spirit comes in through the wall, I bet everybody yells, “Norm’s ghost!”
“The Nerdist,” 9 p.m., BBC America: Chris Hardwick’s guests include Seth Rogan, Natasho Leggero and Zach Galifianakis.
Sunday: “The Killing,” 7 p.m., AMC: I’m sure I’ll tune in for tonight’s 2-hour, third-season premiere even though last season was killing me.
“The Women’s Concert for Change: Live from London,” 8 p.m., NBC: This global female empowerment event includes performances by Beyoncé, John Legend, Florence + the Machine and others.
