Choose a watermelon with a uniform shape and no dents, cracks, cuts, or soft spots
Look for a dull, matte rind rather than a glossy one
Check the field spot (the creamy yellow underside): choose a deep yellow to golden color
Select a watermelon that feels heavy for its size
Tap the rind and choose one that sounds deep and hollow
Prefer a rind that is firm and not easily punctured by gentle pressure
Avoid overly large watermelons that feel unusually light
Avoid watermelons with webbing, bruising, leaking, or moldy spots
Check the stem end: it should be dry and intact (not wet or decayed)
If buying pre-cut watermelon, choose pieces that are cold, fully sealed, and without excess liquid
Choose containers with clear labeling and the latest sell-by date
Wash the outside before cutting to reduce contamination risk
