The dog days of summer make the days long but the weeks short. How is August already around the corner? It’s sweltering here in Los Angeles, well into the nineties, because July and August are our two hottest months of the year. So what can make it more bearable? Piling up on the couch in the A/C might help, and you might need some new TV to watch; or if you’re traveling on your summer vacation and there’s a long flight ahead of you and you need some streaming ideas, I’ve got you!

Here’s the best of what’s currently available through major viewing platforms. Many of these series are also available for free through your local library’s Hoopla and Kanopy platforms. With these shows, I purposefully kept some descriptions vague for some lesser-known mysteries that have big twists so I don’t give too much away and spoil it for you, but just know I’ve vetted every single recommendation on this list.

Here are the top thirty murder mystery television shows and limited series now streaming in July and August across all platforms.

30. Resident Alien - Seasons 1&2 on Netflix, Season 3 on Hulu

(Limited series, 42-72 minute episodes, 7 episodes total) Things are heavy in the world right now, so maybe a murder mystery injected with a ton of humor is the way to go. If so, Resident Alien should be your first pick. The talented Alan Tudyk (Firefly) heads up an ensemble cast that includes Corey Reynolds (The Closer) and Sara Tomko (Once Upon A Time). An alien crash-lands in a small Colorado town and assumes the identity of a vacationing physician. There’s been a murder, and the community needs a new doctor, so the alien decides to fake it until he makes it. It’s brimming with snarky jokes that, fortunately, don’t undermine the more serious topics it sometimes tackles (addiction, adoption, abuse). Linda Hamilton and Terry O’Quinn make guest appearances.

29. Longmire - Netflix

(Six Seasons, 43 minute episodes, 63 episodes total) Fans of westerns who appreciate a good mystery will love Longmire, a show based on Craig Johnson’s mystery series. Walt Longmire is a small town sheriff in Wyoming who recently lost his wife. In a way similar to Fox Mulder’s hunt for his sister, or Monk’s hunt for his wife’s murderer, Longmire is struggling with grief as he seeks justice, even if he doesn’t know where to look. As he upholds the law in his rural town, he finds himself juggling more political and societal relationships than he’d like. In a world full of Sherlocks, Longmire is John Wayne, Lee Van Cleef and Clint Eastwood rolled into one. This show entices viewers who don’t typically gravitate toward mysteries, so if you’re looking for an atypical crime drama, this is perfect.

28. Bloodline - Netflix

(Three Seasons, 55 minute episodes, 33 episodes total) In Bloodline, the black sheep of the family returns home to his family’s estate in the Florida Keys. This one decision — reuniting with his family — comes with scary consequences. Bloodline benefits from an exemplary cast, including
