How to Tell if a Watermelon is Bad?

You can tell if a watermelon is getting rancid by its appearance. If it’s discolored, mushy, or smells bad, it’s time to throw it out. The skin should have a bright color, and the flesh should be free of any blemishes. If a watermelon has a strong, foul odor, throw it out.

There are also some warning signs to look for. If a watermelon’s flesh is soft and mushy, it’s time to toss it. A tangy, sour, or foul-smelling smell is another sign that it’s also past its storage time. Consult a food expert if unsure how to tell a ripe watermelon.

11 Ways to Tell if Watermelon is Bad

Watermelon is a light sweet summer food that is refreshing. You can use it to make fruit salads, serve it with meals, drink it when you’re thirsty, and eat it whenever you want.

On the other hand, shopping for watermelons is a gamble for many people. You don’t want to end up with a melon that’s bland and unripe.

You can tell whether your watermelon has gone wrong in various ways.

This post will teach you how to check for wrong or rotten watermelon and how to identify if your watermelon is fresh or not.


1. Senses of Smell and Taste

Watermelons are sweet, juicy, and delicious. When you bite into a melon, and it tastes sour, you know it’s gone rotten, which is because the melon’s sugars have become sour.

You must smell the watermelon before purchasing it to determine whether it is good or terrible. You’re looking for a watermelon with a sweet, pleasant aroma. Don’t buy it if it smells acidic or sour; it’s already rotten.

2. Press on the Sides

Listen to the sound the watermelon makes as you tap it. A deep hollow sound indicates that the melon is in good condition. If the melon sounds full, it is either past its prime or not quite ripe.

If you tap the watermelon and make a dull sound, it’s mushy or rotten inside.

3. Examine for Mold

The mold or patches on the watermelon’s rind indicate it has gone wrong. Any black, white, or greenish-blue soggy areas indicate that the melon has gone wrong.

4. Watermelon Patch

When looking at the patch or ripe place on a watermelon’s skin, you can tell if it’s terrible. It’s a good watermelon if the patch is yellow.

If the patch is white, it is not ripe and thus unfit for consumption. A yellow watermelon spot suggests that the fruit has been sun-ripened.

5. Rinse the color

On the outside, the watermelon should have a healthy, consistent pine green color or a striped appearance of darker pine and lime green color. The watermelon should also have a dull, non-shiny appearance.

It is not ripe if it is glossy. On the surface, the stem should not be apparent. Instead, look for a bit of crater that indicates the melon has fallen off by itself. A stem indicates that it was picked before it was fully ripe.

6. The Form

Choose a watermelon that is symmetrical and circular. The watermelon is decaying inside if it has an uneven form.

A watermelon with cuts, dents, or irregular lumps suggests that the water supply was variable or that the melon was not pollinated properly. Watermelon cuts or dents could indicate the presence of fungus or insects.

7. Body mass index

A nice watermelon should have a lot of weight to it, and this is due to the melon’s fiber and water content. Watermelons with more weight are sweeter and juicier. A rotten watermelon is lighter, indicating that it has less water.

A watermelon that is lighter than usual suggests that the inside of the watermelon is drying out.

8. color

When cutting a watermelon, look for deep pink or crimson flesh with black seeds; however, seedless watermelons are also available.

This indicates that the melon is ripe, sweet, and nutritious. If the watermelon has changed color, it hasn’t gone nice and should not be consumed.

9. Rough and Tumble

Watermelon flesh that is dried and grainy is no longer appropriate. This is because the gritty flesh will wither and tear away from the seeds over time, becoming mushy and slimy.

This watermelon has reached its peak of ripeness. Refrigerating your melon leftovers will prevent them from becoming dry and grainy due to air exposure.

10. Stability

Scratching the rind or skin of your watermelon with your thumbnail can reveal how resistant it is. If the skin of the melon easily cuts through or yields to pressure when pressed, it is rotten or overripe. The flesh will break down and become sagging and black if it is wet in water, which may result from a fungal infection.

The melon’s interior should not be mushy. The inside of the watermelon is exposed to the air, resulting in a mushy watermelon. Toss your watermelon if it’s slimy, mushy, or discolored.

11. Date of Expiration

When you buy a pre-cut watermelon, it usually has an expiration date on it. However, this does not guarantee that the melon will not rot before the deadline.

If you eat watermelon that has a sour, fizzy, or tangy flavor, although it hasn’t passed its expiration date, spit it out and toss the rest away.

What is the Best Way to Keep Watermelon?


Watermelons are recognized for being tasty and having high water content, making them ideal for eating on a hot summer day. Watermelons have an issue in that they spoil rapidly if not correctly stored after purchase.

The length of time your watermelons remain before deteriorating or rotting is determined by how you keep them.

Make sure your watermelon is kept cool and dry. When keeping your watermelon, cut it in half and place each in a plastic bag on the refrigerator’s bottom shelf. Because they are not touching the cold frozen surfaces of the fridge, this will lessen the time it takes for your watermelons to perish.

If you keep uncut watermelon in the fridge, you must consume it within ten days, or it will go wrong. Also, please don’t keep your melons near ethylene-producing fruits or vegetables, as this can cause them to spoil quickly.

Watermelons are large and difficult to store in the refrigerator. To keep them fresh for longer, cut them into pieces and cover them in plastic wrap. Remove only as much watermelon as you use, and preserve the remainder in an airtight container.

Whole watermelons can be stored at room temperature and from the sunlight without turning rancid. However, you must keep them refrigerated for at least two weeks after acquiring them.

Wrap the cut end of the watermelon with plastic wrap tightly. This will prevent the watermelon from absorbing the flavors of other items in your refrigerator.

How do you Know when Watermelon should Not be Eaten?

It’s critical to recognize that the shelf life of your watermelon is determined by how long it’s been sitting at the supermarket. Local grocers have lower turnovers than big chain grocery stores, which daily stock their shelves with fresh produce. Knowing whether your watermelon is spoilt will keep you from being unwell due to food poisoning. Watermelon is a perishable fruit that begins to decay immediately after being cut.


One of the most delicious summertime treats is watermelon. You can eat it raw, in salads, or make a simple sorbet. However, if you don’t store it properly, it can spoil quickly. Rotten watermelons look and smell mushy and are too heavy for their size. If these enticing treats have tempted you, read this article to learn how to identify a sour watermelon.

A watermelon’s color is a good sign. It should be bright green. If it has yellow or white stripes, it’s probably not a good one. Otherwise, it’s time to discard it. If it’s too pale, you might as well look for a different fruit. And if it’s too pale, you can’t eat it. A watermelon’s flesh should be reddish or pink. It should not be overly sour, and the seeds should be intact. A watermelon with spoilt flesh will have a faded appearance and smell sour. The smell of watermelon is essential. Unlike popsicles, watermelon has the most natural flavor.
