How long does Watermelon last in the fridge?
Turning the range into a date
Watermelon keeps 3–4 days in the fridge from purchase. The window here is 4 days, short enough that the day it went in is worth writing down.

One of the largest freezer gains in the data
Freezing pays off here more than it does for 85% of the 179 foods where the USDA publishes both figures. The freezer gives 90 times what the refrigerator gives: 4 days against 12 months. On the same shelf it sits 75 of 89, between Greens at 4 days and Marinated vegetables, in oil at 4 days.
Every storage figure the USDA publishes for this item
All three places the USDA recognizes are rated here — pantry, refrigerator and freezer — which only 65 of the 466 foods in the data manage. Within Produce it is filed under Fresh Fruits.

What the USDA adds in words
The USDA attaches 1 handling note to this item, reproduced below word for word. It is not a storage time: it qualifies the figure above rather than replacing it. These are the source's own sentences, not ours, and they are the part of the FoodKeeper record that a table of durations cannot carry.
In the pantry, from the day you bought it. Or until ripe.
Can you freeze watermelon?
Yes. The USDA gives watermelon 12 months in the freezer, and held at 0 °F food stays safe beyond that: the figure is about quality. Most produce goes soft when thawed, so frozen it suits cooking, smoothies and sauces rather than eating raw.
How to tell if watermelon has gone bad
Go by the date first: watermelon keeps 3–4 days in the fridge. Mold, slime, a sour smell or soft dark spots mean it goes out; firm produce can be saved by cutting 1 inch around a small moldy spot, soft produce cannot. Refrigerate cut or peeled produce within 2 hours.

Is it still safe to eat, or just past its best?
The answer at the top of this page reads 3 days to 4 days in the fridge. What decides that is the food and not the shelf the source files it on: Watermelon is raw and whole. Past it, whether it has gone bad is yours to judge by look and smell: this window rates quality, not the day it turns hazardous.
It is past the date. Now what?
Say the calculator above puts Watermelon past its 3 days to 4 days in the fridge window. Past that the calendar stops deciding and the food itself does. Mold, a slimy or sticky surface, soft or darkened spots, or a sour smell mean it goes out whatever the date says.
The whole rule, including the cases the source does not cover, is set out under what to do when the date has passed.
Two places, and one of them is the wrong one
The USDA rates two places for Watermelon in one state and they disagree: 3 days to 4 days in the fridge against 1 day to 2 days in the pantry. This page answers with the refrigerator, the longer of the two. Both figures are the USDA's own, so this is a choice of where to put the food rather than a disagreement about how long it keeps.
Items that behave the same way
All 6 of the 6 items nearest this item keep exactly as long as it does, 4 days, so the ranking around it is a tie rather than an order.
Where these numbers come from
Every storage time on this page is the USDA’s own published figure from the FoodKeeper data, one of the 9 it keeps per food, reproduced unchanged and never an estimate of ours. Where the USDA lists several kinds under one name, each kind keeps its own windows, and the page names the kind its answer is for. The dates and multipliers are ours, computed from those ranges.
