How do I know when a watermelon is good to eat?
There are quite a few ways to determine if a watermelon has reached peak ripeness, which would mean it is in perfect condition to eat.

1. Do a thump test. A ripe watermelon should have a deep hollow sound when you thump the rind with your hand, similar to a knock on the door. An unripe melon will have a more high-pitched resonance, whereas an overripe melon will sound more like a thud.

2. Check the field spot. A field spot (or ground spot) is the underside of the melon that rests on the field as it grows. A yellow spot is a good sign that the watermelon was left to ripen on the vine long enough. A ripe melon will have a buttery or creamy yellow field spot along its belly, and a less ripe melon will typically have a white field spot.

3. Feel its weight. When comparing two watermelons of the same size, the heavier one is more likely to be ripe. An unripe watermelon will feel lighter and less sturdy than a ripened, juicy watermelon. However, a melon that feels too heavy can also indicate overripeness.

4. Smell the melon. You will be able to smell the sweet watermelon aroma through the rind of a ripe watermelon. A watermelon is likely underripe if you can’t smell anything through the rind. However, if the smell is too strong it might be overripe.

5. Check the tendril. Watermelon has a curly tendril where the fruit was connected to the vine during the growing process. If the watermelon is ripe, the curly tendril should be almost completely dried out. If the curly tendril is green, the watermelon was picked too early and is not ripe. This method may not work at the grocery store but can help when growing watermelon in your own garden or choosing one at a local farmer’s market.

6. Squeeze the flesh. The best watermelon is juicy yet firm with just a little bit of give in the rind. If the outer rind is soft, it may indicate an overripe or malnourished fruit. You can also try pressing the blossom end of a watermelon. An unripe watermelon will have a completely solid blossom end, while an overripe melon will be mushy and mealy.
Are there any other ways to determine it's ripeness?
Yes, there are a few other methods to determine the ripeness of a watermelon:

1. Look at the sugar spots. Sugar spots are small, white, raised spots on the rind of a watermelon. They are a sign that the watermelon is ripe and sweet.

2. Check the stem. If the stem is still attached to the watermelon, it should be dry and shriveled. If the stem is still green, the watermelon was picked too early and is not ripe.

3. Tap the watermelon. A ripe watermelon will have a dull sound when you tap it, while an unripe watermelon will have a more metallic sound.

4. Observe the color. A ripe watermelon will have a uniform, dull color all over the rind. If the watermelon has a shiny, bright green color, it is not ripe.

5. Check the shape. A ripe watermelon will have a symmetrical shape, while an unripe watermelon will have an irregular shape.

These are some of the additional methods you can use to determine the ripeness of a watermelon.
