IT'S SCIENTIFICALLY PROVEN that sun and alcohol are natural partners—a fact that Portland's drinking establishments are well aware of. Here are some of the best patios around town on which to test this hypothesis for yourself.

Prost!

Okay, not a huge patio, but nothing trumps a refreshing German beer when the thermometer is pushing 90. It's usually bumping, but an outdoor bar accommodates the thirsty hordes. Plus, there's an adjoining food cart pod if bratwurst or sauerkraut isn't your thing. 4237 N Mississippi

Departure

An extensive terrace provides views of downtown and panoramic scenes across Portland. Pricey, but top-notch drinks—and you get to rub shoulders with Portland's version of Eurotrash and California transplants who miss the scene at the Standard in LA. 525 SW Morrison

Rontoms

This splendid patio has mixed seating options and fire pits, making it attractive to larger groups. It gets busy and then busier—watch out for eager hipsters hustling the ping-pong tables, even if you're mid-game. 600 E Burnside

Bar Bar

After working your way through the confines of the bar, emerging onto the patio is a revelation—it feels like there's a whole new world to explore. Check out the monthly burger and the enterprising Scotch list. Groups of 20 or more can reserve a space. 3939 N Mississippi

Teote

Tucked away up the stairs and out the back of this Latin American street food restaurant, the patio has a secluded, secretive feel. Served by its own outdoor bar, it's partially covered, providing shelter from the sun—a necessity when the smooth margaritas are slipping down too easily. 1615 SE 12th

The Landmark Saloon

Unpretentious honky-tonk tavern sporting a generous-sized but mellow patio. Plenty of seating options, and it's dog friendly. For the competitive/active, there are several cornhole lanes. 4847 SE Division

White Owl Social Club

A patio wonderland! It's big, there's a fire pit, and no lack of seating so you're (nearly) always guaranteed a table, even in a large group. And then there's the legendary vegan beet burger—still going strong. 1305 SE 8th

Noble Rot

Eastside wine bar boasting citywide views from the fourth floor. Choose from one of their 40-plus wines by the glass, and watch the sun sink behind the West Hills. The menu features bounty from their rooftop garden. 1111 E Burnside

Paymaster Lounge

A neighborhood bar with a serious patio—fully protected from the elements, yet filled with light. There's seating for as many as 50, so you're likely to find space for your butt. The bar food menu (with six flavors of fries or tots) is above average. 1020 NW 17th

Cyril's at Clay Pigeon Winery

Possibly the prettiest patio in town, and one of the calmest (unless the bocce ball starts to get rowdy). It's also the best place to enjoy excellent cheese and wine al fresco. 815 SE Oak
