Expect beach bonfires, Fourth-of-July fireworks, and the series’ trademark soundtrack of indie pop bangers. Why the weekly drop matters Unlike Netflix’s all-at-once model, Prime Video’s staggered release keeps The Summer I Turned Pretty in the social-media conversation for nine straight weeks, fueling TikTok edits, team-Conrad vs. team-Jeremiah debates, and Thursday morning office chatter. For viewers, that means avoiding spoilers is easier, while each cliff-hanger has a full seven days to marinate. How to catch up before hitting play All 15 episodes from Seasons 1 and 2 are currently streaming on Prime Video. A quick refresher: • Season 1 ended with Belly kissing Conrad on the beach. • Season 2 saw Susannah’s passing and Jeremiah discovering Conrad and Belly’s secret relationship, setting up the final love-triangle showdown. Tips to optimize your streaming experience 1. Watch in UHD: Prime Video streams in 4K HDR for compatible devices. 2. Enable subtitles: The show’s acoustic indie soundtrack sometimes drowns out dialogue. 3. Use X-Ray: Pause to see actor bios, song titles, and trivia mid-episode. 4. Set a reminder: Tell your Alexa device “Remind me when The Summer I Turned Pretty new episodes are available” to get alerts at 3 a.m. ET every Wednesday. The bottom line The Summer I Turned Pretty new episodes promise nine more weeks of sun-soaked drama, swoon-worthy romance, and tear-jerking goodbyes. With a locked-in schedule, exclusive Prime streaming, and the original author steering the finale, Season 3 is poised to dominate summer watchlists and trending charts alike.
