How extreme does Sai Kung's weather get?

The hottest, coldest, wettest and snowiest days Sai Kung has recorded — the outer limits of what its weather can do, and how far they sit beyond a normal day.

Based on 21 years of daily weather observations (2004–present), from the Sha Tin station 7 km away. Updated through August 2025 — an all-time extreme only changes when a more extreme day actually occurs, so some dates are old. That is normal, not stale data.

In plain terms

Across the record, Sai Kung has reached as high as 100°F and as low as 25°F. A single day has delivered over 8 inches of rain. Those are the outer edges worth knowing if you are moving here, planning a trip, or thinking about a house.
