Do Ice Cubes Melt in the Sahara at Night?

Desert Nights Are Cool—But Not Freezing

Yes, ice cubes melt in the Sahara after dark, just more slowly than at noon. Here's why:

• Diurnal swing: Daytime highs often exceed 45°C (113°F); nights drop to 15–25°C (59–77°F) in summer, near freezing in winter.
• Radiative cooling: Dry sand loses heat rapidly via infrared emission to clear skies.
• Low humidity: Dry air has low heat capacity, accelerating cooling—but also lowering the dew point, so no frost forms unless temps hit 0°C.
• Wind: Nocturnal breezes enhance convective heat loss from the ice surface.

Result: Ice melts all night at a reduced rate. Only in winter, on rare sub-zero nights, might it survive until dawn.
