When buying a tent, one of the key factors to consider is its waterproof rating, measured in millimeters (mm). You’ve likely come across tents with ratings such as 1000mm, 2000mm, or even higher. But what does a 2000mm waterproof rating really mean, and is a tent with this rating good enough for your outdoor adventures? In this article, we’ll break down what the 2000mm rating means and assess whether it’s suitable for different camping conditions.
What Does the 2000mm Waterproof Rating Mean?
The waterproof rating of a tent is a measure of how much water pressure the fabric can withstand before it begins to leak. It’s measured in millimeters, and this figure represents the height of a column of water that the fabric can resist before moisture seeps through.
For a tent with a 2000mm waterproof rating, this means the fabric can hold up against a 2-meter (6.56 feet) tall column of water before water penetrates. This rating is often used to assess the tent’s ability to withstand rain, snow, or wet conditions while keeping you dry inside.
Is 2000mm Waterproof Enough for Your Tent?
Whether a 2000mm waterproof tent is good for you depends on the weather conditions you expect to encounter on your trips. Let’s look at a few different scenarios to see how well a 2000mm rating will hold up.
Light Rain and Drizzles
For light rain or drizzles, a 2000mm waterproof rating is more than adequate. In most cases, you won’t experience water pressure high enough to overwhelm a tent with this rating during light rainfall.
If you’re planning on camping in mild conditions, where rain is light and infrequent, a 2000mm waterproof tent will easily keep you dry and comfortable.
Moderate Rain
In moderate rain, a 2000mm tent can still provide good protection. Most moderate rainstorms don’t create enough water pressure to penetrate a 2000mm tent, as long as the rainfly is set up correctly and there are no weak points in the seams or zippers.
In such weather, proper tent setup is crucial. Ensure your tent is pitched tightly, with the rainfly covering the entire structure to prevent water from pooling on the roof or dripping into vulnerable areas.
Heavy Rain
When it comes to heavy rain, a 2000mm waterproof tent can still work, but it might not be ideal for prolonged periods. A heavy downpour can produce a lot of water pressure, and the sustained rain could cause the tent fabric to start leaking, especially if it’s older or worn out.
If you expect to camp in regions with frequent or intense rainfall, you may want to opt for a tent with a higher waterproof rating, such as 3000mm or 5000mm, for extra peace of mind.
Storms and Strong Winds
In stormy conditions, a 2000mm tent might struggle. Strong winds can force rain against the tent with greater pressure, pushing water through even waterproof fabrics. A 2000mm rating might not be enough to withstand the combined effects of wind and rain, especially if the storm lasts several hours.
In these cases, a higher waterproof rating and a sturdier tent design would provide better protection. Look for tents with reinforced seams and stronger poles to handle the elements.

Factors That Affect Tent Waterproofness
A tent’s waterproof rating is just one part of the equation. Other factors can affect how well your tent will keep you dry, even with a 2000mm rating.
Tent Fabric
The type of fabric plays a significant role in waterproofing. A 2000mm tent made from polyester or nylon is common, and both materials can be coated with polyurethane (PU) to enhance waterproofing. However, thicker fabrics tend to provide more durability and better resistance to water over time.
Some tents use siliconized coatings or proprietary waterproof membranes to improve performance. These can make a 2000mm tent more effective in tough conditions.
Seams and Zippers
Waterproof fabric alone won’t keep you dry if water can sneak in through the seams or zippers. Always check whether the tent has taped or sealed seams. Sealed seams prevent water from entering through the stitching, which can be a weak point in many tents.
Waterproof zippers are also important, especially on the tent’s doors. Rain can easily seep in through poorly designed zippers, so look for tents with covered or reinforced zippers for added protection.
Ventilation
It may seem unrelated, but good ventilation contributes to the tent’s overall waterproofing. Poor ventilation can lead to condensation forming on the inside of your tent, which can make you feel like your tent is leaking, even when it isn’t.
A tent with proper ventilation, like mesh panels and adjustable vents, will reduce condensation buildup and keep you dry and comfortable.
Tent Footprint or Groundsheet
The waterproof rating also applies to the tent floor, but the floor is often subjected to more wear and tear than the walls or roof. Using a tent footprint or groundsheet underneath your tent adds an extra layer of waterproof protection to the floor and extends the lifespan of your tent. Even a 2000mm-rated floor can benefit from this extra layer, especially in wet or muddy conditions.
When Is a 2000mm Tent Not Good Enough?
While a 2000mm waterproof tent is sufficient for many camping situations, there are certain conditions where it might not hold up as well.
Snow Camping
If you’re planning a winter camping trip where snow is a factor, a 2000mm waterproof rating might not be enough. Snow can melt and refreeze, creating pressure on your tent’s fabric, and it can also cause condensation to build up on the inside. In snowy environments, you’ll want a higher waterproof rating—preferably 3000mm or more—to handle the moisture and cold.
Tropical Rainforest or Monsoon Weather
In areas with tropical climates or monsoon seasons, rain can come down in sheets for extended periods. A 2000mm waterproof tent may struggle to keep you dry in these conditions. You’ll want a tent with a higher rating, such as 5000mm, to endure the relentless rain without leaking.
Multi-Day Storms
If you’re expecting to camp through a long-lasting storm, especially in exposed areas like open plains or high-altitude campsites, a 2000mm tent may eventually start to leak. Wind and rain combined can increase water pressure on the tent fabric, making it more likely for moisture to seep through over time.
How to Improve a 2000mm Waterproof Tent’s Performance
Even if your tent is rated for 2000mm, there are ways to improve its performance in wet weather.
Use a Rainfly
A rainfly is a separate waterproof cover that goes over your tent. It provides an additional layer of protection and helps water run off the tent rather than pooling on top. Many 2000mm tents come with rainflies, but if yours doesn’t, consider purchasing one separately.
Apply a Waterproofing Treatment
If your tent’s waterproofing starts to wear out over time, you can use a waterproofing spray to re-treat the fabric. These sprays create a water-repellent layer on the surface, helping to keep the rain out. Be sure to clean the tent first and follow the manufacturer’s instructions for the best results.
Re-Seal the Seams
If you notice water leaking through the seams, you can use seam sealant to re-seal them. This is especially important if your tent is older or has been exposed to harsh conditions.
Conclusion: Is a 2000mm Waterproof Tent Good?
A 2000mm waterproof tent is generally a good choice for most camping trips in mild to moderate weather conditions. It’s capable of withstanding light and moderate rain, making it suitable for weekend trips, hikes, and general outdoor use.
However, if you plan to camp in extreme conditions—such as heavy storms, snow, or tropical downpours—a tent with a higher waterproof rating may be a better investment. Consider your camping environment and the potential weather challenges before making your decision.
With the right setup, care, and additional protection like a rainfly or groundsheet, a 2000mm waterproof tent can serve you well for many outdoor adventures. Just make sure to prepare for the worst-case weather scenario to ensure you stay dry and comfortable.
