Does Watermelon Go Bad?

The unfortunate answer to this is yes. Watermelon, much like other and most, if not all, fruits go bad. There is a reason why farmers automatically harvest the watermelon only when it is nearing the peak of its ripe age.

They do this because watermelon is, in fact, one of the fruits that do not just go bad but quickly as well. This reality also means that watermelon, as much as possible, has to be consumed immediately.

It goes without saying that unlike some fruits, watermelon has a minimum storage life . This short shelf life could be because watermelons are composed of a considerable quantity of water and sugar.

As a result, it is easy for microorganisms, such as bacteria, to grow in certain areas. Once the watermelon is sliced, it pretty much becomes like sugar water.

As a word of advice, consume everything as soon as it comes to the peak of its ripe age. This is not just for the sake of being able to eat it before it goes spoiled.

You want to eat the watermelon when it is in prime ripe condition because that is when it tastes best as well.

You can vividly savor the juices and feel their delicious and sweet taste, perfect for combating that summer heat.

How to Know if It Watermelon has Gone Bad

It is critical to know how to tell if watermelon is bad. We have two methods listed below that will help you with how to know when watermelon is bad.

Method One: To Check for Signs

How to tell if a watermelon is bad

Watermelon showing cracks

1. Spots some molds on the exterior

The first step to find out whether your watermelon has gone bad is to spot for signs. That first sign you need to look for are any dark spots also better known as molds.

These molds are usually the spots that stand out when spotted at the exterior of your watermelon. If it doesn’t, then you are going to need to dig a little deeper. Literally.

2. Check the color

Watermelon has that stereotypical appearance of being stripped. It is an alternating pattern between dark green and a lighter shade of green.However, there is also another look for watermelon and that is a consistent shade of green that resembles a pine.

3. Analyze the watermelon flesh

Cut open your fruit and examine the fruit flesh. What you will first notice, if your watermelon has already gone bad, is that it has already started to shrivel.At times, the seed is already distancing themselves away from the flesh. At other times, the flesh can also turn a little slimy.

4. Check the smell

The smell can be a big giveaway on whether your fruit has already gone bad. Chances are if it now smells a bit tangy or sour, then it is time for you to throw it away.

Method Two: Through Dates

How to tell if a watermelon is bad

1. Check the expiration date

As for this method, the rule of thumb is to follow this if what you are eating is the pre-cut watermelons. The first step to managing these types of watermelon is to check the expiration date.

2. Store in the refrigerator

You may opt to do this for at least the first two to three days. Please take the liberty of eating your watermelons after this given time duration.Otherwise, you probably should try to look for the same signs that I have mentioned in the first step.

3. Evaluate each cut

Since these watermelons are already pre-cut, the signs you have to look for are a bit different from the whole watermelon.For this step, check each cut individually. Examine the smell and the color of the flesh.

How long does watermelon stay good for?

  • An uncut watermelon can be kept on the counter at room temperature for up to 10 days.
  • An uncut watermelon can be kept in the fridge for up to 3 weeks.
  • A cut watermelon is good in the fridge for about 3 days.

How to Extend Storage Life

How to tell if a watermelon is bad

  • There is no better advice than to refrigerate your whole watermelons. For best results, do this at a temperature of about 55 degrees.
  • If you are eating the pre-cut watermelons, the best way to keep it fresh is to store it in air tight containers in the fridge.

How to pick a watermelon

A good watermelon should be free of bruises and rotting spots. It should feel heavy compared to other watermelons of its size. A ripe watermelon will be cream colored on the bottom.

Step 1: Visual Inspection

Do you see any bruises, rotting spots or holes in the watermelon?

Step 2: Pick it up

Is it heavy? It should feel heavy. Watermelon is almost completely water. If it feels light for its size compared to other watermelons it isn’t good.

Step 2: Pick it up

The bottom side of the watermelon, where it was laying on the ground, should be creamy in color. If it is white it isn’t ripe. If it is bright yellow, it is overripe.

When is watermelon in season?

The watermelon season ranges from June to September in the United States. However, these days you can often buy cut up watermelon year around in the grocery stores.

However, keep in mind that the winter months will likely not produce the sweet and juicy watermelon that we all love. During the winter season the watermelon tends to come from Mexico and Central America.

Can you freeze watermelon?

You can freeze cut watermelon. You should not attempt to freeze a whole watermelon. If you freeze watermelon make sure to remove the seeds. It is best to only freeze seedless watermelons.

Freezing watermelon will change the texture of the watermelon when you defrost it. We recommend that you freeze it in small chunks and defrost it slowly in the fridge.

The bottom line

Watermelon, indeed, goes bad. It is easy to find out whether it already has. Look for empirical evidence; check its exterior appearance, the look of the flesh and the smell.

However, despite its limited storage life, there are different methods you can employ to ensure that its life can be extended.

Of course, the number one rule you have to keep in mind is to refrigerate it well. And lastly, to use proper means of storage.

How to Avoid Choosing a ‘Bad’ Watermelon

Check the Expiry Date

Prior to deciding on a watermelon always check the recommended ‘Best Before’ date. This will give you an indication of how long you have before this watermelon will begin to turn ‘bad’. Often supermarkets will put the cut watermelons with the longest shelf lives behind those with shorter shelf lives.

How to Recognize if a Whole Watermelon is ‘Bad’

Some watermelon enthusiasts choose to purchase a whole watermelon opposed to pre-cut quarters. Without seeing the flesh of the melon you have to base your judgement on the quality of the skin. The skin of a watermelon is thick so it can be difficult to figure out if the flesh will be juicy and fresh or not.

  1. Pick up the whole watermelon and check it’s entirety for any signs of mold (black, white or green) or dark colored spots. Mold and/or dark colored spots are true indicators that this is definitely not the best watermelon to pick.
  2. Look at the color of the watermelon. A fresh watermelon should be a pine green color often with a striped appearance.

How to Recognize if a Cut Watermelon is ‘Bad’

When you purchase a pre-cut watermelon you gain further knowledge of the flesh condition. Consider the two factors mentioned above along with the the following:

  1. Look at the color of the flesh. A fresh watermelon’s flesh should be pink or deep red in coloring (note this may vary across different types of watermelon for example a yellow fleshed melon).
  2. Look to see if the seeds of the watermelon are intact. Often in a spoilt watermelon, the flesh will begin to shrivel away from the seeds.
  3. The watermelon should smell sweet not sour.

Determining When a Watermelon Should Not be Consumed

It is important to understand that the shelf life of your watermelon will depend on how long it has been sitting in the supermarket. While big chain food retailers generally stock the shelves with fresh fruit daily, local grocers tend to have smaller turnovers. Knowing when your watermelon is considered ‘spoilt’ will ensure you do not fall sick from food induced illness. Watermelon is a perishable fruit that begins to deteriorate at a steady pace the minute it is cut.

Do not eat watermelon that:

  • Has visible mold or large dark areas
  • Appears discolored or has apparent ‘slime’
  • Has a strong sour smell

If your watermelon shows signs of any of these factors, it is always a good practice to throw it in the bin.

You don’t want to buy or eat a watermelon that is bad so I have created this post to give you a list of things to look for. The way it looks on the outside is a good indicator of how it will be on the inside.

How to tell if a watermelon is bad

How to tell if a watermelon is bad is as simple as looking it over and smelling it. If it looks bruised, damaged, or has mold in it then it is not good. Also if you notice that it smells bad do not eat it.

3 Signs to tell if a watermelon is good

Knowing if your watermelon is good to eat or not is important so that you aren’t eating spoiled or moldy watermelon.

You want to make sure that you eat cut-up watermelon within 3-4 days and if you haven’t cut it yet it will last about a week left out before it starts to turn bad.

You can leave a whole watermelon uncut in the fridge to lengthen the freshness for up to two weeks.

Let’s go over the obvious signs of how to know if a watermelon is bad.

You really want to check these things before you cut a watermelon.

1. How does it look?

Look at the outside and make sure that there isn’t any mold or dark spots on the rind. If the outside of the watermelon looks damaged then it has probably affected the inside of the fruit as well.

Watermelon should have dark and light green alternating colors on the outside and a dark pink reddish inside when it is fresh.

If the inside color looks dull you may want to check the other signs as well. Any signs of mold inside or outside are indicators that you should not eat it.

2. Smell it

The outside of watermelons doesn’t have much of a smell to them but you may notice a slight sweet smell. If you smell mold or mildew at all then you want to discard it.

The same goes for the inside of the watermelon. If you have cut it up and you are not sure if it is good because it looks ok then smell it for a sweet smell.

It should smell like it tastes. A nice light sweet aroma.

3. Feel gritty or dry?

If you notice that your watermelon is gritty or dry then it is past its prime. You may notice that the flesh of the watermelon is separating from the seeds or the rind.

The first step in how to tell if watermelon is bad is to look for any molds or rotting on the surface.

If you see black spots or molds on the skin, it’s probably spoilt and should be thrown out.

Red-brown patches indicate that some parts have been eaten by bugs, which is also a sign that your watermelon has gone bad!

Step 2. Check If There Are Any Leaks.

If there are, it’s spoiled!

Step 3. Smell Your Watermelon!

There are many ways on how to tell if the watermelon is bad, and one of the best ways is by smelling it! If it smells like a strong smell of ammonia or sour milk, then you know that your watermelon has gone bad and should not be eaten.

Step 4. Check The Color Of The Watermelon

Another step in how to tell if a watermelon is bad is to look at the color pattern.

​The color of the watermelon helps to identify if it has gone bad. Watermelon generally has a strip of alternating pattern between dark and lighter green. Check the color- if it is pale, it has gone bad.

The flesh should be very bright green if it is still good, but if the color is dull or has started to turn brown, it’s probably gone bad. Dark brown patches also indicate that your fruit has gone bad, so better avoid it at all costs!

Step 5. Tap On The Surface

Tap on the surface of your watermelon and listen closely to check for a hollow sound. If you hear a deep sound, then the watermelon is fresh. If it’s not as “deep” or hollow sounding, then your fruit has started to go bad!

Step 6. Feel For Soft Spots On The Outside Of The Watermelon –

If there are soft spots on the watermelon, this indicates that it’s bad and should be thrown out.

Step 7. Squeeze The Watermelon To Check For A Hard Or Soft Texture.

A ripe fruit will have a softer feel than an unripe one. A ripe watermelon will also be heavier than an unripe one.

The texture of watermelons will also change from soft to hard when they start spoiling.
