How extreme does Düzce's weather get?

The hottest, coldest, wettest and snowiest days Düzce 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 Adapazari station 63 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 Düzce has recorded — each shown against what a normal day that time of year looks like.

In plain terms

Across the record, Düzce has reached as high as 106°F and as low as 15°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.

Methodology & sources

Temperature & precipitation — 1991–2020 normals computed from 18 years of daily observations at Zonguldak, a weather station, about 86 km from the city centre. The underlying daily records come from NOAA's global station network.
