How to Tell if a Watermelon is Ripe: A Comprehensive Guide


Watermelons are a beloved summer fruit that people enjoy as a healthy snack or as the perfect addition to a barbecue or picnic. However, choosing the right watermelon can be tricky, and biting into an unripe one can be disappointing. In this article, we will explore how to tell if a watermelon is ripe, giving you the information you need to select deliciously ripe watermelons every time you purchase them.

Visual Clues

One of the most obvious visual clues of a ripe watermelon is its texture, which should be smooth and firm and free from dents or bruises. A ripe watermelon will also have a dull, not shiny, skin which is an indication of maturity. The color of a watermelon also plays a significant role in its ripeness. A ripe watermelon will have a vibrant green color on the skin, and it turns dull when it becomes ripe, which is an indication that it is ready to be harvested. Another visual aspect to look for is the shape of the watermelon. A ripe watermelon should be uniform in shape with a slight bulge on one side, which is the part of the melon that rests on the ground while it grows.

To make identifying visually clues easier, you can use photos or videos that showcase the different visual aspects of a ripe watermelon.

Three Easy Indicators

There are three popular indicators when it comes to identifying ripe watermelons:

1. Thump Test

The thump test is an easy and quick way to tell if a watermelon is ripe. Give the watermelon a good thump with your fingers, and if it produces a hollow sound, it’s ripe. The sound should be similar to tapping on a table or your chest cavity – deep and resonant. If the watermelon doesn’t give off a deep sound, it is not yet ripe, and if it makes a high-pitched sound, it’s overripe.

2. Yellow Spot

Another indicator of ripeness is looking for a creamy or yellow spot found at the bottom of the watermelon where it sat on the ground. The spot should be creamy or buttery yellow, not white or green, which indicates that the watermelon is not quite ripe yet.

3. Uniform Shape

A ripe watermelon should be symmetrical and uniform in shape, so look for one without large irregular bumps or soft spots.

Expert Insights

To get some expert insight, we reached out to some farmers and gardening experts, and while some of the indicators may conflict with those given by others, one thing that came up many times is that watermelon ripeness varies with the variety.

For example, watermelons that are ripe usually feel heavy for their size, and some varieties may even have a dull thud in sound instead of a hollow thud when appropriately ripened. Color is another key indicator noted by experts, and while some watermelon types may have a yellow spot at the bottom when ripe, other watermelon types may not show a significant color difference whether it is ripe or not.

Actionable Steps

Here is a step-by-step guide on how to tell if a watermelon is ripe:

  1. Start by selecting a watermelon that shows the color, size, and shape that you prefer.
  2. Lift the watermelon and examine its weight. It should feel heavy for its size, which indicates it is full of water and that it’s ripe.
  3. Look for a uniform shape, without lumps or soft spots.
  4. Look for a creamy or buttery yellow spot at the bottom, which is an indication that the watermelon is ripe.
  5. Gently thump the watermelon, and listen for a deep, hollow sound, which indicates it is ripe.
  6. If all indicators are in place, you can purchase your watermelon with confidence knowing that it is ripe and ready to enjoy!

Other Considerations

While the indicators mentioned thus far are generally useful, keep in mind that different types of watermelons can behave differently when indicating ripeness. The best way to know the ripeness that your watermelon type indicates is by doing research or consulting with experts.

One of the other alternative ways to determine the ripeness of watermelon involves examining its color patterns. One of the key color changes in ripe watermelons is the contrast between the darker green stripes and the lighter green stripes; this contrast becomes more significant as the watermelon ripens.

Recipes that Require a Ripe Watermelon

Now that you know how to identify a ripe watermelon, it’s essential to understand why it matters. A ripe watermelon enhances almost every recipe that calls for it, from watermelon salads to agua frescas and cocktails.

Some of the recommended recipes that require a ripe watermelon are watermelon salad with goat cheese and candied walnuts, watermelon juice, and watermelon granita. A ripe watermelon is easier to blend and juice, and it has a sweeter and bolder flavor when compared to an unripe one.

Mitigating the Drawbacks of Ripeness

One of the potential downsides to selecting a ripe watermelon is that it may become too overripe or underripe when you get it home. But don’t worry; there are still plenty of ways to enjoy it!

If you find yourself in a situation where your watermelon is too overripe, you can slice it up and use it to make refreshing watermelon juice. You can also use it as the base for a delicious watermelon cocktail. On the other hand, if your watermelon is underripe, consider using it to make a watermelon feta salad or a tangy watermelon salsa.


The ability to select a ripe watermelon is an essential skill that everyone should have, and with the information provided in this article, you can now confidently choose the best watermelons for your needs. So next time you are in the market for a watermelon, remember to use the visual clues, easy indicators, and expert insights provided in this article to determine the perfect watermelon for you.
