As summer weather starts its slow fade to fall, it’s time to pack in the most open-air fun as possible. This week’s list of things to do has plenty of outdoor activities to fill the shortening days, from a concert in Hudson River Park to Manhattan’s first-ever Smorgasburg. Enjoy yourself, and as always, check Groupon for more great things to do in New York City.

Lit Crawl Manhattan East Village | Saturday, September 13 This three-hour event puts a literary spin on a bar crawl as participants follow their maps to readings and book-themed activities at 25 East Village watering holes. Compete in rounds of “literary Taboo” at Solas, or take in a performance by Farrar, Straus and Giroux house band the Savage Detectives at Leftfield. See the full schedule of events here. (Multiple venues; 6 p.m. to 9 p.m.; free)

Lorde & Majical Cloudz Midtown | Sunday, September 14 Gothy pop wunderkind Lorde claims she’s no royal—but her fans may beg to differ. This Sunday, the 17-year-old New Zealand native holds court at JBL Live at Pier 97, where she’ll set heads bobbing to chart-topping hits like “Tennis Court” and “Team.” Majical Cloudz’s wistful, electronica-tinged indie pop kicks things off. (Hudson River Park at W. 58th St.; 6 p.m.; $74; get tickets here)

AHOYsters Tribeca | Tuesday, September 16 At this punning New York Oyster Week event, the crew of the F/V Sherman Zwicker invites landlubbers aboard their historic schooner for a shellfish-centric feast. Docked at Hudson River Park’s Pier 25, the Zwicker features more luxurious accommodations than the oyster boats of yore: guests pull up chairs to white-clothed tables at Grand Banks, the vessel’s onboard oyster bar. (N. Moore St. at West St.; 6 p.m.; free)

Sex Tips for Straight Women from a Gay Man Hell’s Kitchen | Through Sunday, September 28 This live-action rom-com starts with a meet-cute between shy college student Robyn and brash advice-giver Dan, the gay male author of the book Sex Tips for Straight Women from a Gay Man. As Dan helps Robyn loosen up in front of her crush, Stefan the stagehand, audiences get in on the naughty fun: bachelorettes who purchase a party package even get to join the characters onstage. (777 8th Ave.; tickets $55–$66.50 through GrouponLive)

Smorgasburg at Central Park Central Park | Friday, September 19 For those tired of trekking to Brooklyn, Smorgasburg has granted you a reprieve. This Friday, the foodie festival brings 30 of its top vendors to Central Park SummerStage for its first-ever outing in Manhattan. Chow down on treats from ‘burg stalwarts like Blue Marble Ice Cream, Ramen Burger, and Mighty Quinn’s Barbeque, or newcomers like Dan & John’s Wings or tostada-slingers El Super. (72nd St. and 5th Ave.; 5–9 p.m.; free) Photo credits: Ky Huynh (Lit Crawl), Annette Geneva (Lorde).
