1) “Rescue HI-Surf” season-finale, 9 p.m., Fox. On his daughter’s graduation day, Sonny confronts his friend Vince – who’s been dealing drugs from the lifeguard stand. His team, awash in romantic woe, has a bigger task, rescuing snorkelers. It’s a mildly interesting hour, with a party-time finish (shown here).
2) “American Idol,” 8-10 p.m., ABC. “Idol” slides into its twice-a-week mode, putting it head-to-head with NBC’s “The Voice.” That begins (today and Sunday) with “Hollywood Week,” including group performances.
3) “The Menopause Revolution,” 10 p.m., ABC. At 48, Oprah Winfrey says, “I thought I was dying.” She wasn’t; her heart palpitations were a sign of upcoming menopause. Now, at 71, she gathers experts and others, including actresses Halle Berry and Naomi Watts, comedian Leanne Morgan and journalist and women’s-health advocate Maria Shriver.
4) “NCIS: Origins,” 10 p.m., CBS. When a military sergeant is brutally killed in her car, Franks suspects the case is related to the attack on his estranged wife. That follows an “NCIS” in which a “girls night out” turns into an arson investigation.

Starting today, all 20 episodes stream on Acorn. Another gem: George Lucas’ “American Graffiti” (1973) is at 8 p.m. ET on Turner Classic Movies.
