Best Tent for Heavy Rain: Ultimate Buyer’s Guide [2021]

There is nothing worse than waking up with wet feet, soggy socks and a soaked sleeping bag. This is something we have all experienced when camping. However, it doesn’t have to be this way. That is why we are determined to help you find the best tent for heavy rain. 

 We know how frustrating it is when your tent leaks so we have scoured the market to find the best tent for heavy rain. We have done this by looking at the specific features which affect a tents waterproof rating. The waterproof rating is determined by the Hydrostatic Head (HH) test. This tells you how many millimetres of rain your tent can withstand before it begins to leak. A tent can have a HH rating of anywhere between 200mm – 10,000mm. However, when looking for the best tent for heavy rain a HH between 3,000mm-5,000mm will be enough to withstand even the heaviest downpours.

So let’s dive in!

What Should You Be Looking For When Buying the Best Tent For Heavy Rain (Click To Expand)

 This measurement tells you how waterproof the tent is. It is measured in millimetres and the higher this number the more rain the tent can withstand. A tent is classed as waterproof if it has a HH of 1,500mm or more. To be completely honest, this is nowhere near enough for staying dry in a tent; even in light rain. Instead, you should be looking at a HH of 3,000mm-5,000mm.

This is how well air passes through the tent. This may not seem important but when it is raining it is unlikely you will be able to leave doors and windows open. A good tent will offer excellent ventilation even when it is sealed shut. This is an important consideration because a well-ventilated tent will prevent condensation from building up inside the tent (therefore keeping you dry).

Most tents are manufactured using Nylon or Polyester. The latter of these is treated with polyurethane to make sure they are waterproof. Tents can also be made using cotton, poly-cotton and PVC-Coated Canvas. These all have natural waterproof qualities but are extremely heavy (especially when wet) and therefore are not popular.

 Tent poles are typically made of steel or carbon-fibre. Carbon-Fibre is great because it is ultra-lightweight and easy to pack/store. Steel is better in large tents because the stiffness adds stability. Some manufacturers have started to design inflatable tents. These are an interesting idea but we have yet to be sold on their long-term functionality.

If you are looking for a heavy rain tent it would suggest that you may have, at some point, to either erect or take down the tent in the rain. Having a tent which has a simple and efficient design should be high on your list of priorities. Let us be clear though, a pop-up tent will not be the greatest heavy rain tent – make sure you balance the need for an easy set-up against the need to stay dry.

How heavy your tent should depend on the type of camping you are undertaking. If you are expecting to hike with the tent then look for something lightweight which can also be attached to the external part of your backpack. If you are car camping then the weight is less of a consideration.

With heavy rain, often comes the heavy wind. Look out for wind resistance features such as guide ropes and pole material.

How to Stay Dry: What Do You Do In A Tent When It Rains?

How Do I Keep Water Out Of My Tent?

Seam Sealer

This is a waterproof gel which is created for use on the seams of your tent. One of the more common reasons a tent becomes less waterproof is because the seams begin to wear and the chemicals applied to make them waterproof need to be renewed. No tent will be completely waterproof until the seams are sealed. 

How do I know if I need to use seam sealer?

You can tell by looking at the condition of your tent seams. If they have a glossy look and are smooth to touch it usually means they are in good shape and you do not need to use seam sealer. If the seam is frayed or exposed then there is huge potential for leakage so you will need to apply seam sealer. 

Best Seam Sealer For Tents

Waterproof Spray

Most tents are manufactured using waterproof treatments. Over time, this will begin to wear off, making it vital that you replenish and replace it. To do this, you need to use a waterproof spray or DWR coating. 

DWR coating can be used on all materials such as rainflys, tarp and footprints so this is a sound investment which will help keep you dry.

How do I apply Waterproof Spray?

Firstly, begin with a clean and dry tent. Make sure you have cleaned any debris and dust off the fabric of the tent. Failure to do this will interfere with the adhesion of the product. 

Secondly, make sure you follow the manufacturers instructions. Each spray will be unique in how it should be applied to your tent. 

Thirdly, spray the tent onto the fabric. Ensure it is evenly coated across the entire material. Any area not covered will not provide protection from the rain. 

Finally and if possible, apply heat to the material. Ironing the fabric is ideal. This will help the spray marry with the fabric offering even more protection.

Tarp & Footprints

The best tent for heavy rain will all come with a tarp and footprint. Sometime’s these are included inside the fabric of the tent (rather than being removable). We will discuss what a tarp and footprint is in the FAQ’s but to briefly recap. 

A tarp is a cover which is placed above the tent. It acts like a waterproof cover. 

A footprint goes underneath the tent. It protects the floor from rocks and sharp objects. A footprint will be waterproof and adds insulation for those cold nights.

Frequently Asked Questions ​

Whether or not a tent can withstand rain is determined by its Hydrostatic Head (HH) measurement. HH is measured in mm and indicates the force of water needed before fabric or material begins to leak. Imagine a column of water 2 metres high (2000mm); the weight of that water being forced down onto a material creates a given pressure, generating the hydrostatic head measurement. The greater the column of water, the greater the pressure and the more waterproof a fabric will need to be in order stop the water penetrating the fabric.

Therefore the best tent for heavy rain will have a high HH rating – this means that the number of mm it can withstand will be higher. Basically put, 5000mm is better than 1500mm. 

This is tough to answer because it comes down to personal circumstance. The higher HH tents are usually premium tents and cost more money. Also, you may not need a tent with a HH of 5000mm because you will never be in conditions which require that level of water-proofing.

Putting this into context, a power-jet washer for your driveway has a typical HH of 1000mm for 980bar of pressure. For a tent to be classed as waterproof it must have a HH of least 1000mm. For the best heavy rain tent you will want to be looking at HH of at least 2500mm.  

The best tents for heavy rain are, by their nature, well sealed. This is often only possible by compromising on ventilation. This can lead to a build up of condensation in the tent. Therefore, your tent is not leaking and the water inside the tent is condensation. This is a fine balancing act and for top end tents this is usually not an issue. For budget tents with a high HH rating you may need to do some manual ventilation. You can do this by opening doors and windows to allow the air to flow through the tent. 

Water-resistant tents are able to resist moisture and minimise moisture seeping into the fabric. Water-resistant tents will not prevent moderate to heavy rainfall from entering the tent.

Water-repellent is a coating which is applied to the outer fabric of the tent. It will prevent more water than a water-resistant tent but is still not waterproof. It will repel light rain but anything more and the fabric will begin to let in the moisture. 

Waterproof tents have a HH of at least 1,500mm. In theory, they should prevent rain from entering the tent. However, most tents which are advertised as waterproof do not do this. Instead, you still find water entering the tent. A true waterproof tent will have a high HH level, good ventilation and is well-constructed.

The best tent for heavy rain will come with an in-built footprint or with one which you can attach. A footprint has other benefits. It helps to protect the inner tent fabric from tears and rips will keep the inside of the tent clean from mud and dirt (it is much easier to clean a removable a footprint than inner tent fabric). A footprint will also add insulation to your tent for those cold camping nights. 

Tarp, or tarpaulin, is a cover made from strong, yet flexible materials. Tarp is used to protect you from the wind, rain and sun. At a minimum, they are water-resistant but most will be waterproof. Tarp is extremely versatile and can be used to add waterproofing to the floor of the tent or as an additional roof. In some hot climates people will forgo a tent and just use a tarp as a cover. 

You can put tarp under your tent but I personally prefer using a footprint as these are more cushioned and have better insulation qualities which can help keep you warm. 

There are many ways to set up tarp as an additional roof above your tent. The easiest method is to create a simple frame with two poles. If you don’t have poles you could always use natural objects such as study trees. If using poles, add guylines to increase stability. Once you have a stable base, you can use the poles and guylines to hang the tarp over. To change the shape of the tarp all you need to do is amend the angles of the guylines.

Most tents are treated with a waterproof coating. If you have just bought your tent this should last for a while so you don’t need to worry. 

If you have an older tent the waterproof fabric will become less effective over time. This could be the result of natural wear & tear, UV damage or the fabric fraying because of structural problems such as rips and tears. You should be able to see if the waterproof coating is waring off because the tent fabric will begin to flake.

Fortunately, there are some easy ways to replenish the waterproof coating. Below these FAQ’s we recommend our favourite waterproof spray and seam sealer. Go check these out if you think you need to reapply a coating to your tent. 



If you already own your own a tent then there are things you can do to improve its waterproof rating. This is really easy to do and will help save you money. You can make a tent more waterproof in a few ways In this article we discuss how you can do this before recommending some of our favourite products. 

As a general rule, if you are using a tent for less than a month a year you will only need to reapply a waterproof coating every 2-3 years. 

If you apply seam sealer and waterproof spray to your tent regularly you will be saving yourself a load of money compared to buying a new tent. If you are looking for other shortcuts then I would probably urge caution. What might seem like a bargain idea now may not be so hot when you wake up in a wet puddle with all of your gear soaked from a night of heavy rain. 

Yes, you can sleep in a tent with mold but I would advise cleaning as much off the fabric as possible. Scientific studies have shown that long term exposure to mold can affect people who have asthma and/or other chest problems. 

That being said, as a one-off you will be fine with exposure to mold. 

All of the waterproof sprays we have recommended have been researched and tested by us independently. All of these worked on new and a variety of old tents. They also worked well across different material types and tent styles. 

Most tents have a waterproof coating and seam sealer applied as standard by the manufacturer. I would always recommend carrying some seam sealer and spray with you as part of your gear so it can be applied if your tent begins to leak. 

A 2,000mm tent will endure a 2-metre column of water-bearing down on it before it leaks. This sounds a lot but it is the equivalent of a light-moderate rain shower. 

1,500mm is widely accepted as the measurement tents need to meet in order to be classed as waterproof (beware that this is not an international standard so always check your tents HH measurement before buying). 

That being said, 1,500mm will keep you dry in light rain. It may withstand a very short heavy shower. But, in prolonged rain, it will begin to leak. For the best tent for heavy rain, the minimum HH measurement you should look at is 3,000mm. 

When you touch the tent fabric you draw water to your finger. Since it is often humid inside a tent when it is raining the condensation will build-up until you get a drop. This is why you should avoid putting objects such as your bag or boots on the tent fabric on a wet evening. 


Conclusion: Best Tent for Heavy Rain

In this article we have discussed the properties a features of the tents designed for heavy rain. The best tent for heavy rain are, in our opinion, manufactured by Snugpak. These tents are renowned for their ability to withstand heavy rain with a HH rating of 5000mm.
