If you’ve ever stood in the produce aisle wondering how to know if a watermelon is seedless, you’re not alone.
 
It’s a common question, and the answer is simpler than you might think.
 
In this post, we’ll cover exactly how to tell if a watermelon is seedless, the physical signs to look for, and a few myths you can ignore.
 
By the end, you’ll be able to pick a seedless watermelon with confidence every single time.
 

How to Know If a Watermelon Is Seedless: The Key Signs

Learning how to know if a watermelon is seedless starts with understanding what makes them different.
 
Seedless watermelons aren’t actually 100% seedless.
 
They contain tiny, white, undeveloped seed coats that are completely soft and edible.
 
So when we talk about seedless watermelons, we mean the ones without those hard, black seeds you’d spit out.
 
Here are the main signs that tell you if a watermelon is seedless.
 

1. Look for a Rounder, Uniform Shape

Seedless watermelons tend to be more round and uniform in shape compared to seeded ones.
 
Seeded watermelons are often more oblong or oval.
 
So if you see a watermelon that’s perfectly spherical and symmetrical, there’s a good chance it’s seedless.
 
This isn’t a foolproof method on its own, but it’s a strong hint when combined with other signs.
 

2. Check the Size

Seedless watermelons are usually smaller than seeded varieties.
 
They typically weigh between 10 and 20 pounds, while seeded watermelons can grow much larger.
 
If you’re holding a watermelon that feels surprisingly light for its size, that’s another clue.
 
Knowing how to know if a watermelon is seedless often comes down to these small details.
 

3. The Thumping Test

Give the watermelon a good thump with your knuckles.
 
A ripe seedless watermelon will produce a deep, hollow sound.
 
A dull thud usually means it’s overripe or underripe.
 
While the thumping test doesn’t directly tell you if a watermelon is seedless, it helps you pick a ripe one.
 
And ripe seedless watermelons are what you’re after.
 

4. Look for a Creamy Yellow Field Spot

Flip the watermelon over and look for the field spot.
 
This is the patch where the watermelon rested on the ground.
 
A creamy yellow spot means it’s ripe.
 
A white or green spot means it was picked too early.
 
This sign won’t tell you if a watermelon is seedless, but it’s essential for picking a sweet one.
 

Why Seedless Watermelons Look and Feel Different

Seedless watermelons are grown through a special process that involves cross-breeding.
 
They’re created by crossing a diploid watermelon with a tetraploid one.
 
The result is a triploid watermelon that can’t produce viable seeds.
 
That’s why the seeds you find inside are white and soft instead of black and hard.
 
Understanding this helps explain why seedless watermelons have a different texture, shape, and size.
 
It also explains why they’re often a bit more expensive.
 
The growing process is more labor-intensive, and the yields are lower.
 
But for many people, the convenience of not dealing with seeds is worth it.
 
Knowing how to know if a watermelon is seedless is really about recognizing these unique traits.
 

Common Myths About Identifying Seedless Watermelons

There are plenty of myths floating around about how to know if a watermelon is seedless.
 
Let’s clear a few of them up.
 

Myth 1: All Seedless Watermelons Have No Seeds at All

This isn’t true.
 
Seedless watermelons still have those tiny white seed coats.
 
They’re just soft and safe to eat.
 
So if you cut one open and see white seeds, don’t panic.
 
It’s still a seedless watermelon.
 

Myth 2: You Can Tell by the Color Alone

Color alone won’t tell you if a watermelon is seedless.
 
Both seeded and seedless watermelons can have the same dark green rind with lighter stripes.
 
You need to combine several signs to make an accurate guess.
 

Myth 3: Seedless Watermelons Are Genetically Modified

They’re not genetically modified in the lab sense.
 
They’re created through natural cross-breeding techniques that have been used for decades.
 
So you can enjoy them without worrying about GMOs.
 

Tips for Picking the Best Seedless Watermelon

Now that you know how to know if a watermelon is seedless, here are a few extra tips.
 

1. Pick It Up

A good seedless watermelon should feel heavy for its size.
 
That means it’s full of juice and ready to eat.
 
If it feels light, it’s probably dry and mealy inside.
 

2. Check the Rind

The rind should be smooth and slightly glossy.
 
Avoid watermelons with soft spots, cuts, or bruises.
 
These are signs of damage or spoilage.
 

3. Smell the Bottom

A ripe seedless watermelon will have a faint, sweet smell at the blossom end.
 
If it smells like nothing, it’s probably not ripe yet.
 
If it smells overly sweet or fermented, it’s past its prime.
 

4. Go by Weight

Heavier is better when it comes to watermelons.
 
A heavier watermelon means more water content, which translates to juicier flesh.
 
This tip works for both seeded and seedless varieties.
 

So, How to Know If a Watermelon Is Seedless?

You can know if a watermelon is seedless by checking its shape, size, and the soft white seeds inside.
 
Seedless watermelons are typically rounder, smaller, and have a uniform appearance.
 
They also have those tiny white seed coats instead of hard black seeds.
 
Combine these signs with the thumping test and the field spot check, and you’ll be picking perfect seedless watermelons every time.
