The short answer
Watermelon lasts as long as you store it correctly — which can mean anywhere from a few days on the counter to a year in the freezer. The numbers above represent best quality per USDA and FDA guidelines, not absolute safety limits.
Why these numbers vary
Large juicy summer melon. Storage life depends on temperature consistency, humidity, packaging, and how fresh it was when you got it. Refrigerators that swing between 38°F and 45°F shave days off these numbers; vacuum-sealing or freezing extends them.
How to tell if watermelon is bad
- Mushy or fibrous flesh
- Sour smell when cut
- Foaming or fizzing
Storage tips
- Cube and freeze for slushies
- Juicy texture lost when frozen
- Refrigerate before cutting
