Choosing the perfect watermelon can be a fun yet challenging task.
For instance, is it true what they say that a watermelon should make a dull sound when thumped? And is a yellow spot at the top really that important?
Let’s chat about it!
In this guide, we’ll cover the most tried-and-true methods for selecting a sweet, ripe, and juicy watermelon every time.
7 Signs of a Perfectly Ripe and Sweet Watermelon
Watermelons come in various types, including seedless, picnic, icebox, and those with yellow or orange flesh.
Each type has its unique characteristics, but the principles of picking a good one remain largely the same.
Another factor shared among all watermelon varieties? They are all at their peak freshness during the summer months.
Now let’s look at a few specific “tests” a winning watermelon should pass.
1. Visual Inspection
When it comes to selecting a watermelon, start with a visual inspection.
Look for a uniform shape, whether round or oval. Avoid those with irregular lumps or bumps.
The color of the rind should be a consistent green without any white streaks.
2. Field Spot
One of the most telling signs of a ripe watermelon is the field spot, the area where the watermelon rested on the ground.
A creamy yellow spot indicates that the watermelon ripened in the sun and is likely to be sweet.
Avoid watermelons with white or greenish field spots as they may not be fully ripe.
3. Tapping Technique
The sound test, or tapping technique, is another useful method.
Gently thump the watermelon and listen for a hollow sound. A ripe watermelon will produce a deep, hollow sound, indicating that it is full of water and ready to eat.
4. Examining the Rind
The texture of the rind can also provide clues about the watermelon’s ripeness. Look for a dull and slightly rough surface rather than a shiny or smooth one.
Additionally, brown web-like veins on the surface, known as webbing, are indicators of sweetness.

5. Weight
A good watermelon should feel heavy for its size. This heaviness suggests that the watermelon is full of water, which means it will be juicy.
Compare the weight of different watermelons of similar size and choose the heaviest one.
6. Stem and Tendril
This test is more important if you’re picking from your own garden or a local farmer.
Pay attention to the stem and tendril of the watermelon:
A dry, brown stem indicates that the watermelon was picked at peak ripeness.
As for the tendrils, a curly, brown tendril on the stem end signifies ripeness, while a green one suggests that the watermelon was picked too early.
7. Smell
Another useful indicator is the aroma of the watermelon. A ripe watermelon should have a sweet smell near the stem end. If there is no smell, the watermelon may not be ripe yet.
How to Spot an Unripe Watermelon Immediately
Knowing what to avoid is as important as knowing what to look for.
A shiny rind often indicates that the watermelon is underripe. Mature watermelons tend to have a duller appearance, so a glossy surface can be a red flag. Look for a rind that is more matte and slightly rough to the touch.
The webbing is also critical.
Webbing refers to the brown, web-like veins on the surface of the watermelon. These veins are an indicator of sweetness, as they are caused by sugar seeping out of the fruit. An absence of webbing usually means that the watermelon is not sweet enough and is likely underripe.
How to Store Your Watermelon
Once you’ve selected your watermelon, proper storage is key.
Whole watermelons are best stored at room temperature. They should be kept in a cool, dry place away from direct sunlight. A pantry or a countertop works well.
At room temperature, a whole watermelon can last up to 7-10 days. The quality may start to decline after this period, so it’s best to consume it sooner rather than later.
If you need to store a whole watermelon for a longer period, you can place it in the refrigerator. This can extend its shelf life by an additional week.
Cut watermelon should be kept at a temperature of 40°F (4°C) or lower.
Once cut, store the slices in an airtight container. If you don’t have airtight containers, you can use plastic wrap.
Wrap each piece tightly to minimize exposure to air. Ensure that all exposed flesh is covered to prevent it from becoming dry or mushy.
If you won’t be able to eat it all before it goes bad, place the cut watermelon on a baking sheet lined with parchment paper and freeze for a few hours until solid.
Transfer the frozen cubes to a freezer-safe bag or container. Bear in mind that frozen watermelon is best used in smoothies or as a refreshing addition to beverages.
Thawing and eating it as-is can result in a mushy texture.
We hope this quick guide helps you pick the best watermelon of the season and enjoy it for as long as possible!
