From the way it looks to the sound it makes, little signs reveal what’s happening inside. Use these easy tips the next time you’re at the store or farmers market, and you’ll walk away with a watermelon that’s ready to impress.
Look for a Creamy Yellow Spot

The yellow spot, also called the “field spot,” shows where the watermelon rested on the ground. If this spot is creamy yellow, the melon had time to ripen in the sun, which is a good sign that it will be sweet and juicy.
Avoid melons with a white or very pale spot, which usually means it was picked too early. A watermelon without a yellow spot at all might have been harvested before it was ready. Always check underneath before tossing one in your cart.
Choose a Dull Skin, Not a Shiny One
Shiny watermelons might look nice, but they usually aren’t ripe. A dull or matte finish is a better sign of full ripeness. Shiny skin often means the melon was picked too soon.
The best watermelons have a deep, rich green color with a dusty look. It may not be the prettiest, but it’s probably the tastiest. Don’t let the outside fool you , dull is better for watermelon.
Pick It Up and Feel the Weight
A good watermelon should feel heavy for its size. That heaviness means it’s full of water, making it juicy. Compare a few about the same size, and choose the one that feels heavier.
If it feels light, it may be dry or underripe inside. Watermelons are mostly water, so the juiciest ones are usually the heaviest. Trust your hands, they can tell you more than your eyes.
Tap It and Listen for a Deep Sound
Give the watermelon a tap with your fingers or knuckles. A ripe one will make a deep, hollow sound, almost like a drum. If the sound is flat or dull, it might be overripe or underripe.
The deeper the sound, the more likely the inside is firm, crisp, and full of juice. This trick takes a little practice, but you won't forget it once you hear a good one. Try tapping a few and comparing the sounds before making your choice.
Check the Shape for Uniform Roundness
Look for a watermelon that’s round or oval and evenly shaped. Odd lumps or misshapen sides might mean it grew unevenly or had inconsistent watering. While they might still be edible, they often have a weird texture or flavor.
Uniform shape means it grew in stable conditions, usually leading to better taste. Round watermelons also tend to be sweeter, while long ones can be more watery. Shape matters more than most people think.
Watch Out for Webbing
Webbing looks like brownish, rough veins on the outside of the watermelon. Believe it or not, this is a good sign. It means bees pollinate the flowers often, which leads to sweeter fruit.
The more webbing you see, the better the melon might taste. It may not look perfect, but the flavor will likely be worth it. Don’t mistake this natural scarring for damage; it’s a secret signal of sweetness.
Avoid Soft Spots and Cracks
Give the watermelon a once-over for any soft spots, dents, or cracks. These are signs of bruising, over-ripeness, or poor handling. A good watermelon should feel firm all around, with a consistent texture.
Cracks can also mean the inside has gone mushy or even started to rot. You want your melon to look solid and feel sturdy. If you notice anything that looks off, it’s best to pick another.
Look for a Uniform Color
The best watermelons have a consistent color all over the outside. Uneven coloring or streaks could mean it didn’t ripen properly. A deep green rind with a nice contrast between dark and light patterns is ideal.
The outside should also have that dull finish we talked about earlier. Bright, glossy patches are usually a red flag. Think “balanced” when checking the rind.
Check the Tail if It’s Still Attached
Some watermelons still have a little tail or stem at the end. A dry, brown tail means the melon had time to ripen fully before it was picked. A green tail suggests it was picked too soon and might not be as sweet.
While not every melon has one, it’s a useful hint when it’s there. It’s just one more small detail to keep in mind. If you see a brown tail, that’s a thumbs-up.
Look for Sugar Crystals or “Sugar Spots”
Sometimes you’ll see little black spots or sticky sap on the skin. These are sugar spots and often mean sugar leaks out, a good thing. It usually means the watermelon is extra sweet.
They’re not pretty, but they’re a sweet tooth’s dream. Don’t confuse them with mold; sugar spots are dry and safe. If you see these, you may have found a gem.
Go for Medium-Sized Melons
Bigger doesn’t always mean better. Extra-large watermelons can be less flavorful and sometimes mealy, while small ones can be underripe or overly dense.
Medium-sized melons often strike the best balance between flavor and texture. They’re easier to handle and store, too. Unless you’re feeding a crowd, mid-size is usually the sweetest spot.
Feel the Rind for Hardness
Gently press the outside of the melon with your fingers. A ripe one should be firm and tough, you shouldn’t be able to push in at all.
If the rind feels soft or gives way, it may be overripe or damaged. The hardness protects the juicy inside, so it’s important. It should feel like knocking on a wooden table. If it’s too soft, leave it behind.
Ask Where It Was Grown
Local watermelons are usually fresher because they haven’t traveled far. The longer they take to get to the store, the more time they have to lose flavor and texture. If you're unsure, ask the store or vendor where the melons came from.
Farmers markets often have the best, most flavorful ones. Local also means it was picked closer to peak ripeness. Fresher fruit usually means better taste.
Try Seeded Over Seedless
Seedless watermelons are convenient, but they often have a slightly different texture. Some people say they’re not quite as sweet. Seeded melons tend to have a more classic flavor and juicier bite.
It might be worth the trade if you don’t mind spitting out a few seeds. Seeded ones are also less likely to be overly modified. Give both a try and see which you like better.
Don’t Rely on Color Alone
Bright green doesn’t always mean ripe. Some underripe melons look perfect on the outside. That’s why using a few of these tips is essential.
Don’t judge the fruit by its cover alone. A melon can be pretty but lack flavor. Use your senses, not just your eyes, to find the best one.
