By RIPE, checked against a produce manager's cues. Published .
Flip it over and look at the field spot: a creamy, buttery-yellow patch means it ripened in the field, while a white or pale green patch means it was picked too early. Watermelon does not ripen after picking, so what you buy is what you get.
What to check
👁️
Lookcreamy yellow field spot; dull (not shiny) rind. Brown webbing lines are pollination scarring and completely harmless. Old-timers swear the webbed ones are sweeter; treat that as folklore, not a rule.

Feelheavy for its size. A ripe melon is mostly water.
👂
Sounda knuckle knock should sound deep and hollow, not a dull thud.
Common mistakepicking the shiniest melon. A shiny rind usually means underripe.
Written by the team behind RIPE, a free app that reads a photo of the whole produce pile and rings the ripest ones. Every cue above is one you can check with your own hands, and it all works with no app at all.
Where this comes from
These cues match the public guidance from university extension services. Read them yourself:
You just read the cue for one piece. RIPE reads a photo of the entire display, draws numbered rings on the ones worth taking, and tells you why in the same plain words these guides use. Then it remembers what you brought home and nudges you before it turns.
It claims only what a camera can actually see. Every verdict ends by handing the last check back to your hands, which is the part these guides just taught you.
