How To Pick A Black Watermelon

Picking a black watermelon is easier than you might think once you know what to look for.
 
If you’ve ever stood in the produce aisle wondering how to pick a black watermelon that’s ripe, sweet, and ready to eat, you’re not alone.
 
A black watermelon isn’t a different fruit—it’s simply a watermelon variety with a very dark green rind that looks almost black.
 
Most of these dark-skinned watermelons, like the Sugar Baby or Black Diamond types, are known for being extra sweet and juicy.
 
In this post, we’ll walk through exactly how to pick a black watermelon so you never bring home a dud again.
 
Let’s dive in.
 

How to Pick a Black Watermelon

Knowing how to pick a black watermelon comes down to using your senses.
 
You can’t rely on the rind color alone because black watermelons are dark by nature, even when they’re not ripe.
 
So here are the field spots, sounds, and textures that tell you when a black watermelon is ready.
 

1. Look for the Field Spot

The field spot is the creamy yellow patch on the underside of the watermelon where it rested on the ground.
 
If you’re learning how to pick a black watermelon, this is your number one clue.
 
A ripe black watermelon will have a pale yellow or buttery cream field spot.
 
If that spot is white or green, the melon was picked too early and won’t be sweet.
 
The darker and creamier the spot, the longer it sat ripening in the field.
 
 

2. Check the Webbing and Texture

Black watermelons often show a bit of webbing, those brownish, scar-like lines on the surface.
 
Webbing is actually a good sign because it means bees pollinated the flower multiple times, which leads to a sweeter fruit.
 
Run your hand over the rind and feel for a slightly rough, raised texture.
 
A smooth, glossy black watermelon is usually underripe, while a duller, tougher skin suggests it’s ready.
 
 

3. Give It a Thump

The thump test is one of the oldest tricks for how to pick a black watermelon.
 
Knock on the side with your knuckles and listen carefully.
 
A ripe black watermelon gives off a deep, hollow sound almost like a drum.
 
If it sounds dull or solid, it’s likely underripe or overripe.
 
A high, tight ping usually means the melon isn’t ready yet.
 
 

4. Feel the Weight

Pick up a few black watermelons of similar size and compare their weight.
 
The heaviest one is usually the best pick because watermelons are about 92 percent water.
 
A heavy black watermelon means it’s full of juice, while a light one may be dry or mealy inside.
 
So when figuring out how to pick a black watermelon, always let your arms do some of the deciding.
 
 

Signs a Black Watermelon Is Not Ripe

Just as important as knowing how to pick a black watermelon is knowing what to avoid.
 
Here are the red flags that tell you a black watermelon should stay on the shelf.
 

1. A White or Green Field Spot

If the field spot is white or green instead of creamy yellow, walk away.
 
This black watermelon was harvested too soon and will taste bland and crunchy.
 

2. A Shiny, Waxy Surface

A glossy finish on a black watermelon often signals immaturity.
 
Ripe ones tend to have a more matte, slightly weathered look.
 

3. Soft Spots or Cracks

Press gently around the surface and look for soft, mushy areas.
 
Any bruising or deep cracks means the black watermelon is past its prime or damaged.
 
 

Storing Your Black Watermelon After Picking

Once you’ve mastered how to pick a black watermelon, the next step is keeping it fresh.
 
A whole black watermelon can sit at room temperature for about a week or two.
 
If you want it chilled, place it in the fridge for up to two weeks before cutting.
 
After cutting, wrap the pieces tightly and eat them within three to four days.
 
 

So, How Do You Pick a Black Watermelon?

You pick a black watermelon by checking for a creamy yellow field spot, a hollow thump, a heavy weight, and rough webbing on the rind.
 
Avoid white spots, glossy skin, and soft patches because those are signs the black watermelon isn’t ripe.
 
Use your eyes, hands, and ears together and you’ll almost always land a sweet, juicy one.
 
Now you know exactly how to pick a black watermelon the next time you’re at the market.
