Find the Perfect Location
Choose a place in your yard for the main guest area. Be sure it’s sheltered from the wind. Using the leeward side of a building (the one facing the wind) can work well. Or you can put up some tall shelter-tents, like this one from Big Agnes.
If you can partly cover the area with an awning, or a couple of side-by-side pop-up tents like you see at farmers markets, that will help retain heat.

Set Up a Heat Source
A fire pit adds actual warmth and makes people feel more cozy. You can add fire easily with a chiminea or a smokeless fire pit from a company like Solo Stove or Breeo. Stand-up propane-fired patio heaters, like you see at restaurants, are also a good bet, along with portable Buddy Heaters.
If you go the wood-fire route, make sure to follow fire safety techniques. Whichever heat source you use, place one in a central area or along the outer perimeter of your tent so the heat rises into the enclosure. If you can make a deflection wall behind your fire, that will also direct and enhance the heat radiation.

Serve Hot, Winter-Themed Drinks
Hot chocolate with marshmallows, mulled wine, spiced cider with cinnamon sticks, tea and coffee warm guests from the inside out. Don’t forget about adult drinks, too, like hot toddies (warmed whiskey, lemon and honey), eggnog with rum, Irish coffee and liquors like Irish cream and brandy.
You can keep drinks warm in insulated drink containers or slow cookers. If you’re feeling adventurous, you could even hang a cast-iron cauldron over the fire. But to keep things safe, assign the person tending the fire to also ladle out those drinks.

Cook Festive Outside
One of our favorite outside entertaining centerpieces — for adults and children — is our Pi pizza oven. We set up a pizza bar at one end of the tent, where partygoers can assemble their ingredients, then bake them in the 750-degree flames. The radiating heat from the oven also warms everyone nearby.
Other hearty snacks and finger foods to try include hot dogs, chestnuts and marshmallows/s’mores (each with a roasting station), soup shooters, fondue, charcuterie and festive toppings like whipped cream, nutmeg and cinnamon.

Create Ambiance
Winter-themed decorations and warm lighting add to the cozy festivity. We love these solar-powered string lights and MPowered’s solar Luci lights that flicker like candles. Both offer nice, warm color spectrums. Other good options include tabletop Terraflames and yard tiki torches.
If it’s been snowing, try building a snow-block wall on the side of the guest area. That will deflect and hold heat in the tent area, as well as create a fun storage place for cans of cold beverages.

Feed the Birds
Being outside in winter means endless entertainment from birdwatching. Get an array of feeder types, suet and seeds to attract a range of species. Have some binoculars, a bird ID book and a camera with a zoom lens on hand to make it special for human guests curious about their wild neighbors.
For extra fun, set up a Birdify feeder camera. Guests can download the app and take adorable wide-angle closeups of birds chowing down.

Encourage Winter Activities
Playing outside in winter is a lot of fun, and the exercise warms you up.
Try hosing a scavenger hunt or making snow angels, or go all-out with your own Winter Olympics. Think contests for building snowmen, snowball throwing, winter badminton and sledding. Set up a giant Jenga game, or just take a leisurely nature walk.
With all these activities, you might consider starting your party earlier in the day while there’s still plenty of sunlight.

Warm Up the Furniture
Cover metal chairs with blankets and pillows so people aren’t sitting on cold surfaces. Cover tables with cloth tablecloths to keep people’s arms and hands warmer.
Add some perceived warmth by wrapping brightly colored cloth around cold objects, like potted plants, metal tent poles and pergolas. If you own a sauna or hot tub, don’t forget to fire it up and let your guests know it’s available so they can bring their swimsuits and towels! Of course, if you have a pool, you could also suggest a polar plunge challenge.

Make It a Costume Party
If you really want to get guests into party mode, pick a theme and turn your event into a costume party. Tropical beaches or winter wonderlands are tried-and-true staples. Or get creative with a winter-loving animals or frosty heroes and villains theme.
Don’t forget to put together a matching playlist. Make sure your outdoor speakers work and, if you’re going tropical, blow up the inflatable palm trees and stick those pink plastic flamingos into the snowbank.
Oh! And don’t forget, if kids are invited, there’s Disney’s “Frozen!”

Be Clear About the Outside Part
Whatever you do, don’t surprise your guests about the “outside” part of the party. Let them know about the tent (or tent-less) situation and remind them to bring warm clothing, including a change of socks in case they start having too much fun in the snow.
However, just because you told them, don’t rely on your guests to plan accordingly. People will forget essentials, so collect a basket of extra hats and gloves and keep plenty of blankets on hand. Consider winter party favors, too, like hand warmers and scarves, or custom blankets and hats.
