How Can You Tell If Watermelon Is Bad: Tips For You To Know

Watermelon is a favorite fruit for many people due to its sweet taste and high water content. It is important to know how to identify a bad watermelon to avoid disappointment when cutting into it. By paying attention to certain indicators, you can ensure that you select a ripe and juicy watermelon.

How Can You Tell If Watermelon Is Bad

To determine if a watermelon is bad, check for signs like a soft or mushy texture, a sour smell, or a bland taste. Avoid watermelons with dents, cracks, or moldy spots. Tap the watermelon and listen for a hollow sound. A ripe watermelon should be firm, heavy, and have a pleasant aroma.

Signs of a Bad Watermelon

  1. External Appearance: One of the first things to examine is the watermelon’s external appearance. A good watermelon should have a firm and smooth rind without any dents, cracks, or soft spots. Avoid watermelons with bruises or moldy areas.
  2. Weight: A ripe watermelon will feel heavy for its size because it contains a lot of water. When you pick up a watermelon, it should feel dense and substantial. If it feels too light, it may be an indication that the watermelon has started to dry out.
  3. Sound: You can also determine the quality of a watermelon by tapping it lightly with your knuckles. A ripe watermelon will produce a deep and hollow sound, whereas an overripe or bad watermelon may sound dull or thud-like.
  4. Texture: The texture of a watermelon can provide clues about its freshness. Run your fingers over the surface of the watermelon and check for any soft or mushy areas. A good watermelon should have a consistent texture throughout.
  5. Smell: Give the watermelon a gentle sniff near the stem end. A fresh watermelon will have a mildly sweet and pleasant aroma. If you detect a sour or fermented smell, it is a sign that the watermelon is past its prime.
  6. Taste: If you are unsure about the quality of a watermelon, you can cut a small sample and taste it. A good watermelon should be sweet, juicy, and flavorful. If it tastes bland or has an off-flavor, it may be an indication of spoilage.

Tips for Choosing a Good Watermelon

Now that you are aware of the signs of a bad watermelon, let’s discuss some tips for choosing a good one:

  1. Look for Uniform Shape: A high-quality watermelon will usually have a uniform and symmetrical shape. Avoid watermelons that are misshapen or have irregular bumps.
  2. Check for Yellow Spot: Look for a creamy yellow spot on one side of the watermelon. This spot indicates that the fruit has ripened while sitting on the ground. A white or green spot may suggest that the watermelon was picked prematurely.
  3. Tap and Listen: Lightly tap the watermelon and listen to the sound it makes. A ripe watermelon will produce a deep, resonant sound, while an unripe one may sound dull.
  4. Feel the Surface: Run your hands over the watermelon’s skin. It should feel smooth and firm, without any soft or mushy areas. Avoid watermelons with a hard or rough texture.
  5. Sniff the Watermelon: Take a whiff of the watermelon near the stem end. A fresh watermelon should have a pleasant, fruity aroma. Avoid watermelons with a sour or fermented smell.
  6. Taste a Sample: If the opportunity presents itself, taste a small sample of the watermelon before purchasing it. The flesh should be sweet, juicy, and flavorful. If it tastes watery or lacks sweetness, it may not be of good quality.


Being able to identify a bad watermelon is essential to ensure you enjoy the best quality fruit.

By paying attention to external appearance, weight, sound, texture, smell, and taste, you can determine if a watermelon is fresh or past its prime. Additionally, following the tips provided for choosing a good watermelon will increase your chances of selecting a ripe and delicious one.
