The hottest, coldest, wettest and snowiest days Sungai Petani 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 Butterworth station 23 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, Sungai Petani has reached as high as 102°F and as low as 66°F. A single day has delivered over 15 inches of rain. Those are the outer edges worth knowing if you are moving here, planning a trip, or thinking about a house.
