The hottest, coldest, wettest and snowiest days Xam Nua has
recorded — the outer limits of what its weather can do, and how far
they sit beyond a normal day.
Based on 23 years of daily weather observations (2002–present), from the Sam-Neua station 2 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 Xam Nua

looks like.

In plain terms
Across the record, Xam Nua has reached as high as 103°F and as low as 30°F. A single day has delivered over 7 inches of rain. Those are the outer edges worth knowing if you are moving here, planning a trip, or thinking about a house.
