Tips for choosing ripe watermelons with red flesh, sweet, and paper-thin flesh.

Top Tips for Choosing a Ripe, Sweet Watermelon

1. Check the Field Spot (Ground Spot)

  • Look for a creamy yellow or buttery golden spot on the watermelon’s surface — this is where it sat on the ground and ripened in the sun.
  • Avoid white or very pale spots — those watermelons are likely underripe.

2. Look for Webbing or Sugar Lines

  • The brown, rough web-like patterns (called sugar lines) indicate that bees pollinated the flower multiple times.
  • More pollination = sweeter fruit.
  • It may not look pretty, but webbing is a great sign of a sweet melon.

3. Knock on It – Listen to the Sound

  • Tap or knock on the watermelon with your fingers.
  • deep, hollow sound = a ripe and juicy interior.
  • dull or flat sound = overripe or underripe fruit.

4. Inspect the Shape

  • Pick a symmetrical watermelon — round or oval, but it should be uniform in shape with no dents or lumps.
  • Irregular bumps might mean uneven ripening or poor growing conditions.

5. Check the Weight

  • A good watermelon should feel heavy for its size — that means it’s full of water and juicy.
  • Compare several watermelons of similar size and choose the heaviest one.

6. Examine the Skin

  • The rind should be dull, not shiny. A shiny surface usually means it’s underripe.
  • The stripes (on striped varieties) should have a strong contrast — the dark stripes should be dark, and the light stripes light.

7. Look at the Tail

  • The watermelon’s stem or tail can indicate ripeness:
    • dry and curly brown tail = ripened on the vine (sweet and ready to eat).
    • green tail = likely harvested too early, and may not be fully ripe.

8. Thin Rind Clue: Tap for “Bounce”

  • A watermelon with a thin rind often produces a slightly more resonant, bouncing sound when tapped, compared to thicker-rind ones.
  • While it’s hard to tell rind thickness without cutting, heavier weight-to-size ratio often points to more flesh and a thinner rind.
