The hottest, coldest, wettest and snowiest days Üsküdar has
recorded — the outer limits of what its weather can do, and how far
they sit beyond a normal day.
Based on 22 years of daily weather observations (2003–present), from the Sariyer station 13 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.
The four kinds of extreme
The hottest, coldest, wettest and snowiest single days Üsküdar

looks like.

In plain terms
Across the record, Üsküdar has reached as high as 103°F and as low as 23°F. A single day has delivered over 5 inches of rain. Those are the outer edges worth knowing if you are moving here, planning a trip, or thinking about a house.
