Watermelon breaks the usual cold-chain rule: it must not be stored cold. It is a warm-season, chilling-sensitive fruit, so the job is to keep it cool-but-not-cold and to handle a heavy, easily-cracked melon gently. Get it right and Egyptian watermelon travels well by sea with good shelf life. This guide covers the watermelon cold chain from harvest to reefer, and packing.

Quick answer: Watermelon is chilling-sensitive and held warm — about 10–15°C at 85–90% RHnot near 0°C, because cold storage causes pitting, rind breakdown and loss of flavour. Shelf life is relatively good (around 2–3 weeks in proper conditions). Melons are shipped by reefer at ~10–13°C, packed in bulk bins or cartons (mini melons in cartons), and handled gently to avoid cracking and bruising. Watermelon trades under HS code 0807.11.

The chilling-sensitivity rule

Unlike most produce, watermelon is damaged by cold. Stored below about 7–10°C, it develops surface pitting, rind breakdown, off-flavours and faster decay once removed. So the target is a moderate 10–15°C at 85–90% RH — cool enough to slow ageing, warm enough to avoid chilling injury. This is the single most important handling fact for watermelon.

Remove field heat, but moderately

Melons are harvested in warm conditions, so they are brought down from field heat to storage temperature — but only to the moderate target, not deep-chilled. Because the fruit is dense, it cools slowly; rushing it to cold temperatures does more harm than good. Done correctly, watermelon holds its eating quality for the journey.

Packaging formats

  • Bulk bins — large melons loaded into sturdy bins with padding for sea freight.
  • Cartons — for graded melons and protection in transit.
  • Mini-melon cartons — personal-size watermelons packed by count for retail.

Because melons are heavy and can crack or bruise, they are handled gently, cushioned, and stacked to avoid pressure damage. Each melon’s rind integrity is part of the grade.

Loading and shipping

Watermelon ships by reefer at ~10–13°C with airflow and logged temperature — carefully avoiding cold setpoints that cause chilling injury. The relatively good shelf life makes sea freight practical for the main markets. A temperature recorder in the container gives the buyer proof the chain stayed in the correct warm range.

Quality preservation checklist

  • Hold warm at 10–15°C (never near 0°C) and 85–90% RH.
  • Remove field heat to the moderate target only — do not deep-chill.
  • Cushion and stack carefully to prevent cracking and bruising.
  • Ship by reefer at ~10–13°C with logged temperature.
  • Protect rind integrity — it is part of the grade and shelf life.

Frequently asked questions

At what temperature should watermelon be stored?

Warm – around 10-15 degrees C at 85-90% humidity – not near 0 degrees C, because watermelon is chilling-sensitive and damaged by cold.

How long does watermelon last?

Around 2-3 weeks in proper (warm) storage conditions.

Why can’t watermelon be stored cold?

Cold causes pitting, rind breakdown, off-flavours and faster decay – classic chilling injury.

How is watermelon packed and shipped?

In bulk bins or cartons (mini melons in cartons), shipped by reefer at ~10-13 degrees C with logged temperature.

Why handle melons so carefully?

They are heavy and can crack or bruise; rind integrity is part of the grade and protects shelf life.
