The secret to buying the best watermelon every time
Picking a ripe watermelon one can feel like a total guessing game—but a few simple cues can help you land a sweet, juicy melon every time. As someone who has worked with watermelon a lot, here are my best tips to keep in mind the next time you’re shopping.
Look for the yellow field spot
That creamy patch on the rind is where the watermelon rested on the ground while it ripened. You’re looking for a deep yellow or even orange-tinged spot. If it’s pale or white, the melon is likely not to be at its peak.

Pick it up (yes, really)
A ripe watermelon should feel heavy for its size. That heft signals a high water content, which usually means a juicier bite.
Look for webbing (brown scratchy spots)
Those brown, rough, web-like lines on the rind might not look pretty, but they’re often a good sign. They’re sometimes associated with higher sugar content—aka a sweeter watermelon.

Give it the thump test
Give it a tap. A ripe watermelon typically produces a deep, hollow sound, while an underripe one sounds dull. This one takes a little practice, but it’s a helpful extra signal when you’re deciding between a few options.
The stem is a clue
The stem can tell you something—but it’s more of a supporting character than the main event. If there’s still a bit attached, you’re looking for a dry, brown stem, which usually means the watermelon had time to ripen on the vine.
A green stem can signal it was picked a little too early. That said, plenty of watermelons don’t have much stem left by the time they hit the store, so don’t overthink this one. Your best bet is still to focus on the bigger signs, like that deep yellow field spot and a nice, heavy feel.

The bottom line
Skip the gimmicks. Instead, focus on a golden field spot, a heavy feel, and a few visual clues that the melon had time to fully ripen. Your summer fruit salad will thank you.
