The Bible never mentions snow in the Nativity accounts, and first-century weather records don’t exist. However, clues from geography and history suggest it’s possible but unlikely.
Bethlehem sits in the Judean Hills (~775 m elevation) with a Mediterranean climate: hot, dry summers and cool, wet winters. Snow falls occasionally in Jerusalem and Bethlehem—roughly once every few years—but accumulation is usually light and brief.
Josephus recorded a heavy snowfall in Jerusalem during Herod’s reign, proving winter storms did occur. Yet the peak rainy season (January–February) postdates the traditional late-December birth celebration.
Bottom line: a dusting of snow can’t be ruled out, but a white Christmas in first-century Bethlehem would have been a rare event.
