When you bring a whole watermelon home, it’s best to store it at room temperature away from direct sunlight. This method keeps the fruit ripe for about a week or two, allowing the natural sugars to develop fully without losing nutritional value, which can occur if refrigerated immediately after purchase.
If you’ve sliced into your watermelon, proper storage becomes even more crucial to maintain freshness.
Store cut watermelon by wrapping the pieces tightly in plastic wrap or placing them in an airtight container before refrigerating. This method will help preserve the juicy texture and prevent the watermelon from absorbing odors or flavors of other foods in your fridge. Use the cut portions within three to five days to enjoy the watermelon when it’s still at its best.
When working with an abundance of watermelon, or to enjoy it beyond its peak season, consider freezing it.
Cut the watermelon into cubes or scoop out balls and place them on a baking sheet lined with parchment paper. Freeze these pieces until solid and then transfer them to a freezer bag or container.
Freezing will change the texture, so while frozen watermelon might not be ideal for a classic eating experience, it’s perfect for smoothies or as a fruity ice cube alternative.
Selecting Watermelon for Storage
When storing watermelon, selecting the right one is just as important as how you store it. A ripe, undamaged fruit is essential for optimal shelf life.
Evaluating Freshness and Ripeness
To ensure you’re buying a ripe watermelon, look for one that feels heavy for its size—a sign of high water content and freshness.
A ripe watermelon will also have a firm, symmetrical shape with a uniform color. Check the underside for a yellow spot, which indicates that it has sat on the ground and ripened under the sun.
During watermelon season, sweetness can also be assessed by tapping the melon; a ripe one will emit a deep, hollow sound.
Weight: Heavy for size indicates juiciness.
Sound: Deep, hollow sound suggests ripeness.
Checking for Damage or Bruises
Examine the watermelon for dents, cuts, or bruises, as these can lead to premature spoilage. The skin should be smooth and the rind intact to maintain the watermelon’s shelf life.
If you come across a watermelon with damaged skin, it’s best to avoid it, as the compromise in the skin can affect the fruit’s internal freshness.
Skin: Smooth, undamaged skin is ideal.
Rind: No cuts or bruises, to preserve freshness.

Room Temperature Storage
For uncut watermelons, the best practice is to store them at room temperature before they are cut. This method preserves the fruit’s quality and can prolong its freshness for about 7-10 days.
Keep your watermelon on a countertop or another flat surface away from direct sunlight to avoid over-ripening.
Place of storage: Countertop or pantry
Temperature: Room temperature, ideally between 68°F and 72°F
Duration: Up to 7-10 days
Notes: Keep away from direct sunlight to avoid excessive ripening
Refrigerator Storage
Once cut, watermelons should be refrigerated to maintain their freshness.
Use plastic wrap or an airtight container to cover the watermelon’s exposed flesh. The cold environment of the refrigerator slows down the ripening process and can keep cut watermelon fresh and juicy.
Temperature: Ideally at 55°F
Duration: 3-4 days for optimal freshness
Preparation: Cover cut surface with plastic wrap or place in an airtight container
Rind: Keep intact to preserve moisture
Shelf life: Extend by storing correctly
Storing Cut Watermelon
After you’ve cut your watermelon, proper storage is crucial to maintain its flavor and freshness. By following specific storage methods, you can preserve your cut melon’s taste and texture.
Airtight Containers
For optimal storage, place your cut watermelon into an airtight container. This reduces exposure to air and helps to retain moisture, which is essential for maintaining the melon’s juicy quality.
Preferably, use glass or hard plastic containers with secure lids.
Containers: Use containers specifically designed to be airtight.
Size: Ensure the container is appropriately sized for the amount of watermelon; too large a container has excess air that can dry out the fruit.
Proper Refrigeration
Refrigeration is key to keeping cut watermelon fresh and cold.
Your fridge should be set to a temperature that is cold enough to hamper bacterial growth and maintain the melon’s firmness.
Temperature: Keep your fridge at 37°F (2.8°C) to 41°F (5°C).
Duration: Refrigerated and properly stored watermelon can last for 3-5 days.
Wrapping Techniques
If you don’t have an airtight container available, sealing the melon using plastic wrap is a viable alternative.
Wrap the slices or cubes tightly to shield them from air.
Remember, your cut melon might become softer over time, but these methods help to keep it as fresh and flavorful as possible while refrigerated.
Freezing Watermelon
Properly freezing watermelon can extend its shelf life and provide you with a refreshing treat. The key to successful freezing lies in proper preparation, choosing the right technique, and understanding how to thaw it efficiently.
Preparation for Freezing
Before freezing, select a ripe watermelon and wash its exterior.
Cut the watermelon into cubes or slices depending on your future usage. If you desire them for smoothies or as a cold snack, cubing is most convenient. For best results, remove all seeds.
Freezing Techniques
Arrange the watermelon pieces in a single layer on a baking sheet to prevent them from sticking together.
Place the baking sheet in the freezer and freeze for about an hour—or until the pieces are firm.
Once frozen, transfer the watermelon into a freezer-safe storage bag or container.
It’s important to remove as much air as possible to prevent freezer burn, maintaining the watermelon’s quality during long-term storage.
Thawing Frozen Watermelon
When you’re ready to use your frozen watermelon, transfer it from the freezer to the refrigerator for a few hours to thaw gradually.
For immediate use, like in smoothies or popsicles, you can use it directly from the freezer.
However, note that thawed watermelon will not have the same firm texture as when it was fresh and is best used in recipes like juices, smoothies, or as an ice cream topping rather than as a standalone fruit.
Watermelon Preservation Methods
Preserving your watermelon ensures you maintain both its distinctive flavor and freshness over time. From dehydrated treats to succulent jams, the following methods offer a variety of ways to keep watermelon for future enjoyment.
Dehydrating Watermelon
Dehydrating watermelon concentrates the flavor, making a sweet and chewy snack.
You’ll want to use a sharp knife to cut the watermelon into small pieces, ensuring they dehydrate evenly.
Using a dehydrator, set the temperature to about 135°F and dry the pieces until they are firm, yet pliable. This process can take anywhere from 18 to 24 hours.
Store your dehydrated watermelon in airtight containers to maximize its shelf life.
Canning and Pickling
Pickling transforms watermelon rinds into a tangy condiment that complements many dishes.
To pickle watermelon, cut the rind into small pieces, discarding the pink flesh.
Canning, on the other hand, can involve creating watermelon jams or jellies. The key is to use the watermelon’s natural pectin to set the jam.
Seal your cans properly using a water bath or pressure canner, which can preserve the watermelon for up to a year when stored in a cool, dark place.
Making Watermelon Concentrate
For a refreshment option, create a watermelon concentrate that can be used for drinks, popsicles, or even a chilled gazpacho.
To make the concentrate, puree your cut watermelon with a melon baller or blender until smooth.
Strain the puree to remove any seeds and pulp, then pour it into ice cube trays or a container and freeze.
The concentrated watermelon cubes or blocks can be diluted with water or added to beverages for a taste of summer any time of the year.
Avoiding Common Storage Pitfalls
In ensuring your watermelon remains fresh and flavorful, it’s crucial to navigate around typical storage mistakes that can lead to premature spoilage.
Controlling Temperature and Humidity
Maintain the temperature around 55°F (13°C) for a whole watermelon, as temperatures higher or lower can negatively impact its sweetness and texture.
If you lack a cool storage area, keep the melon at room temperature away from direct sunlight.
Be mindful of relative humidity levels; too much humidity can encourage bacterial growth and decay, while too little may lead to dehydration.
Preventing Flavor Contamination
Keep your watermelon away from foods with strong odors or flavors, as it may absorb them, altering its taste.
Use airtight containers for sliced watermelons to prevent flavor contamination.
If using plastic wrap, ensure it’s tight to keep out unwanted smells that might be present in the refrigerator.
Monitoring for Spoilage
Regularly check for any signs of spoilage, including soft spots, odors, or textural changes that signify decay.
These signs may indicate the presence of damage or bacteria.
If you detect any off-smell or visible indications of spoilage, discard the affected parts to prevent spread to the rest of the fruit.
