How to Choose Ripe, Sweet Watermelon and Melon

As warmer days arrive, watermelons and melons take centre stage at markets and supermarkets, tempting anyone after something cooling, light and naturally sweet. But because a thick rind hides what the flesh is really like, it helps to know a few visual, touch-based and even sound clues so you can pick fruit that is ripe and sweet without relying on luck.

How to spot a sweet, ripe watermelon at the shop?

A watermelon gives away plenty from the outside. The field spot - the patch where the fruit rested on the ground - should be a creamy yellow or slightly orange shade. If that mark is very pale, it often points to an early harvest and less sweetness.

Another useful check is weight compared with size: a heavier watermelon usually means more juice and firmer flesh. A rind that looks more matte, with clearly defined stripes and no excessive shine, generally suggests a more advanced stage of ripeness and a fuller flavour.

Key signs of quality in a ripe watermelon

Beyond appearance, the sound you get from a gentle tap can hint at what’s going on inside. A deep, “full” thud tends to be linked to firm, juicy flesh, while a very high-pitched or metallic note may indicate fruit that is still underripe or has a dry, mealy texture.

The condition of the stem (the little stalk) also helps confirm when it was picked: a dry or slightly curled stem suggests it completed its cycle on the plant. To make judging easier at the point of purchase, check these key points:

• Creamy yellow or orange field spot
• Matte rind with well-defined stripes and no cracks
• Deep sound when you tap it lightly
• Dry or curled stem, not very green
• Heavy weight for its apparent size

How to recognise a ripe, fragrant melon

With melon - including varieties such as cantaloupe, netted melon, yellow melon and the “Piel de Sapo” type - aroma is a decisive ally. A melon ready to eat gives off a sweet, pleasant smell, especially near the stem end. No scent usually means it is underripe, while an overly strong, alcoholic or fermented smell suggests it has gone past its best.

Weight and texture to the touch also help. Among melons of the same size, the heavier one is typically juicier. A slight give at the end opposite the stem, without sinking too much, points to good ripeness without flesh that is overly soft or watery. On the skin, a more yellow background colour (for yellow and netted types) or a deeper, firm green (for “Piel de Sapo”) generally indicates the flavour has had time to develop.

Practical care for storing watermelon and melon at home

A few simple steps when buying and storing will help watermelon and melon stay in good condition for longer. Check that the rind is intact - with no deep splits, mould, or very soft areas - as this lowers the risk of contamination and rapid spoilage, especially on very hot days.

Once home, keep whole fruit in a cool, well-ventilated place for a few days. After cutting, store the pieces in clean, covered containers in the fridge. For netted melons, more pronounced netting and a background colour that is more yellow than green often signal better ripeness, helping you make the most of these fruits throughout summer. Yellow melons and “Piel de Sapo” types usually last a little longer whole outside the fridge, but once opened they should also be refrigerated and eaten within a few days to preserve texture and sweetness.
