Sticking your head in the fridge will cool you off, but these frosty libations, swimming spots, and urban oases provide a longer-lasting chill.

Camp out at picnic tables that catch a breeze from the Delaware. The best defense against Hades-level temperatures? It’s a toss-up between the misting fans and micheladas.

Morgan’s Pier, 221 North Columbus Boulevard (215-279-7134 or morganspier.com).

Roam the massive building, check out DVDs, or even take a guided tour of the Rare Books department. And if the heat hasn’t fried every last brain cell, join the summer reading program.

Parkway Central Library, 1901 Vine Street (215-686-5322 or freelibrary.org).

Air conditioning and a large popcorn count as life’s simple pleasures. Settle in for independent films (take a hoodie; it gets that cold) at any of the three locations before plunging back into the heat.

To find locations, go to landmarktheatres.com.

You can still score a weekday membership to the private pool. The kid-free zone allows you to sip cocktails on a chaise without the risk of getting splashed.

North Shore Beach Club, 1031 Germantown Avenue (215-600-2584 or northshorebeachclub.com).

When shore houses and country club memberships don’t figure into your budget, free admission at public pools across the city comes in handy. Hipsters arrive in droves for adult swim at the South Philly oasis.

Ridgeway Pool, South 13th Street, at Carpenter Street (phila.gov).

While the sun is at its peak, while away time at the retro-inspired alley. Prone to gutter balls? Entertain yourself with vintage arcade games and tater tots.

North Bowl, 909 North Second Street (215-238-2695 or northbowlphilly.com).

Chartering your own yacht is out of the question, but the six-passenger limit on the Summer Wind gives a taste of luxury. Captain Tom compiles sound tracks (reggae, Sinatra) for each cruise. Push off as the sun sets or BYO on the wine and cheese cruise.

American Sailing Tours, Pier 24, Philadelphia Marine Center, 401 North Columbus Boulevard (215-900-7758 or americansailingtours.com).

Grab a shake from SquareBurger (new flavors debut every month) and sit close enough to the fountain to catch a spray of mist. If you can tear yourself away from a shady tree, get old-school kicks on the carousel or miniature golf course.

Franklin Square, 200 North Sixth Street (215-629-4026 or historicphiladelphia.org).

When lifting an icy beverage to your lips is all you can muster, sip a bottle of Pepino Fresco (St-Germain, Cuervo Gold, celery and cucumber juices) or work your way through the Avenue 1111 (Tanqueray, ginger beer, mint leaves) while sitting outside.

Garces Trading Company, 1111 Locust Street (215-574-1099 or garcestradingcompany.com).

Hippos and zebras relish the heat; you take to it like a Humboldt penguin. Seek refuge at indoor exhibits like the McNeil Avian Center or the reptile and amphibian house where actual rainstorms shower the animals.

Philadelphia Zoo, 3400 West Girard Avenue (215-243-1100 or philadelphiazoo.org).

Persuade your friend with a car to make a trip to the Delaware Valley. How to convince her? It’s been a classic destination for more than 40 years and offers kayakers and canoers a quick getaway from the concrete jungle.

On your lunch hour, visit the self-serve fro yo truck that debuted this spring. Swirl flavors like tart blueberry açai or a dairy-free option in a cup, then pile on mochi and rainbow sprinkles from the topping bar.

Every Monday and Thursday, at Love Park, 16th Street, at John F. Kennedy Boulevard (@gozenyogurt).

Last time we checked, swimming in the fountain was a no-no. (Not that the crowd here cares.) Cool off beside blasts of water that shoot from the mouths of frogs and turtles.

Swann Memorial Fountain, North 19th Street, at Benjamin Franklin Parkway.
