How To Winterize a 3 Season Tent

How To Winterize a 3 Season Tent

I get a lot of tent and camping-related questions from friends and family. Since I grew up in Minnesota, I’ve enjoyed the trials of winter camping since I was a child. Because of that, I get a lot of winter camping questions, like: Can you use a 3-season tent for winter camping? 

Many first-time winter campers don’t want to drop more money on a 4-season tent if they don’t know if they’ll like it. Still, being too cold not only can ruin the experience, but it can be hazardous. 

There are a few ways that you can make your 3-season tent work for winter camping; it just takes some additional time and sometimes extra gear. In this article, I’ll detail some of the easiest ways to winterize your 3-season tent. 

First, let’s define the difference between a 3 and 4 season tent…

Before we get any further, you need to know what kind of tent you have. A 3-season tent is generally a tent that is designed to be used in spring, summer, and fall weather conditions. They will have plenty of ventilation on the tent’s body, and the rainfly protects the inside from wind and rain. 

A 4-season tent is also referred to as a winter tent. Hypothetically, you can also use it in the spring, summer, and fall. However, due to the lack of ventilation, campers generally avoid this because of heat retention. 

4-season tents are meant to hold up to extreme weather conditions, often in alpine terrain. If there is a lot of snow and a lot of wind, a 4-season tent is ideal. 

10 ways to winterize a 3 season tent:

When deciding whether to winterize your already existing tent or to invest in a 4-season tent, where you are camping can make a difference. If you are expecting extremely high winds and a possibility of winter storms, you should consider a 4-season tent. If you are going to be camping in mild winter conditions, a winterized 3-season tent will do. 

1. You need a tarp (or two)

Although a three-season tent won’t be much less insulated than a 4-season tent, invest in a few tarps. You want one tarp to act as a footprint underneath your tent. Another tarp to be a cover for the top and trap heat that would otherwise escape the ventilation. 

Then, if you are feeling innovative, one tarp can also work to block the wind. 

2. Insulate the tent floor 

Beyond using a tarp as a footprint on the ground, insulating the floor is always helpful for a comfortable night’s sleep. This can be done quite easily with sleeping pads, but if you want to go the extra mile and are car camping, use some blankets. 

A go-to for winter car camping is a wool blanket large enough to cover the entire floor. Like how a sleeping pad insulates your body heat, putting a blanket across the entire floor insulates all the heat inside the tent. 

3. Make a windbreak

If possible, avoid camping in an open area. In most cases, open areas will be very windy. However, camping underneath large trees can be a hazard as well. Snow may pile up on the branches and fall onto the tent. 

Your best bet is to camp somewhere that is near trees and other vegetation like bushes. If there isn’t anything natural to block the wind, but there is a lot of snow, pile up snow that is tall enough to break the tent’s wind. 

As mentioned before, a tarp can also be rigged up to act as a windbreak. However, you will need something to tie the tarp too, which requires trees or rocks. 


4. Minimize ventilated areas

One of the many differences between a three and four-season tent is that a 3-season tent has more ventilation. Manufacturers of 3-season tents anticipate that you will be using their product in warm temperatures and climates, so ample ventilation is necessary. 

Most 4-season tents have some ventilation, usually one small vent at the top and one near the bottom. This is to prevent condensation and keep a small amount of airflow traveling through the tent without a draft. 

Some 3-season tents are almost entirely meshed material for the interior tent, while others are around half mesh, half solid material. If possible, cover up some of this open mesh material with plastic or a tarp attached to the top of the tent under the rainfly. 

Keep in mind that you want some ventilation, but by covering the majority, heat retention will be higher. 

5. Use all the guylines

A big part of 4-season tent design is wind resistance. That means that the tent is taut and sturdy, likely using a lot of tie-down points. 

Most 3-season tents come with a fair amount of guylines and attachment points to secure in heavy winds. In the winter, always use all of them. Keep in mind that you won’t always have a tree or a rock to tie off your guylines.

Guylines help to keep the fabric of the tent tight. This not only minimizes the noise from the wind, but it also helps so the wind has less to catch as it hits the tent. If it is snowing, a tent with tighter fabric will make it easier for the snow to slide off instead of build up on the walls. 

6. Use winter-specific stakes


That’s why you may need some winter-specific stakes – like the MSR Blizzard Tent Stakes. As you could imagine, normal tent stakes won’t hold well in the snow if a big gust of wind comes up. They do make stakes that are designed to go into and hold in the compacted snow. 

Notice the word compacted here. If you have fresh snow and you are staking out your tent and guylines, be sure to compact the snow where you are inserting the stake. Otherwise, it won’t hold. 

Another option is to use buried objects in the snow, like rocks, to hold a guyline. You can also choose to bury your tent corners if necessary. 

7. Make sure everything is waterproof


When you’re camping in the winter, staying dry is everything. Snow makes all of your gear wet, so having a way to dry and stay dry inside the tent is vital not only for a comfort level but also for safety. 

If your tent is not properly waterproofed before you go winter camping, you’re in for a disastrous adventure. If it does snow while you’re out, the heat from the inside of your tent can easily melt the snow, and as more snow builds up, the wetter it will be. 

You can consult the manufacturer to see what waterproof coating is on your 3-season tent, but if you have had the tent for a long time, the coating will need to be reapplied. You can use a urethane coating and a few other materials to seal the seams like Seam Grip by GearAid (some tent seams come factory sealed).

8. Reinforce or replace the tent poles

Another stand-out feature that differs between a 3-season and a 4-season tent is the poles’ strength. While both tent designs should have strong enough poles to stand up to wind, not all are designed to hold the weight of snow or stand up to the cold. 

You may need to buy new tent poles to successfully winter camp, or at least reinforce them. The main thing to remember is that they need to be sturdy in cold environments. 

While there isn’t necessarily a “best” material for tent poles, aluminum, steel, or carbon fiber materials tend to have the best track record for working in winter settings. Fiberglass tent poles are the cheapest and most common type of tent pole on the market but are not as strong or sturdy. They tend to be far more flexible, which isn’t necessarily what you want when winter camping. 

Aluminum and carbon fiber poles will be very lightweight, which is excellent if you are backpacking in winter. Aluminum poles tend to be more affordable than carbon fiber, but carbon fiber will be slightly lighter. However, if you backpacking and winter camping, get a 4-season tent to save weight. 

Steel poles will be very heavy but very strong. 

9. Bring additional heat sources


If you are car camping next to your car and can afford to bring heavy objects along, bringing a portable heater (like the Mr Heater pictured above) can be a lifesaver. You can run these for a bit to heat the tent’s inside right before bed and before you get out of your sleeping bag in the morning. 

Just be sure that if you use a portable heater of any kind that you do not run as you sleep and enough ventilation in the tent not to trap any fumes. 

10. Borrow or rent winter camping gear

The last, but one of the most important steps on our winterizing list, is winter gear. This means clothes, sleeping gear, and footwear. Even if your tent is winterized, you still need to have a warm enough sleeping bag and clothing to keep you safe. 

Even a 4-season tent requires the use of a cold-weather sleeping bag! If you don’t own a sleeping bag rated for cold weather, consider borrowing one from a friend or renting one. Then if you love winter camping, you can invest in a bag of your own. 

Closing thoughts on winterizing a 3-season tent…

In most winter camping scenarios, having a 4-season tent is my recommendation. You can do it with a 3-season tent, but it will take a lot more gear. That means that it only really works if you are car camping. 

If you plan to backpack in the winter, plan to invest in a 4-season tent because to camp in a 3-season tent safely in cold conditions, you’ll need extra gear. All that extra gear adds too much weight and makes the journey much harder. 

The good news is that winter camping in a 3-season tent can be done, and it can be done comfortably. All you need to do is be prepared and have a few tricks up your sleeve to winterize your 3-season tent.
