Weather extremes

How extreme does Thakhèk's weather get?

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

Based on 34 years of daily weather observations (1991–present), from the Nakhon Phanom station 5 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 Thakhèk has recorded — each shown against what a normal day that time of year looks like.

🔥 Hottest day
113°F Jun 21, 1993

That is about 22°F hotter than a normal June afternoon in Thakhèk (typical high near 90°F).

How hot and cold it gets, month by month

The shaded band is the normal range of daily temperatures for each month. The dots show the most extreme it has ever been — so you can see how far beyond a normal day the records really sit.

Thakhèk's record heat sits well above even a hot day for the season — June's 113°F is about 22°F beyond a normal hot afternoon. Its record cold is just as far below a normal winter night — the dots mark how rare each extreme really is.

In plain terms

In a normal year, Thakhèk's warmest days reach the mid-90s°F and its coldest nights drop to the low 60s°F. But across the record it has gone as high as 113°F and as low as 40°F. A single day has delivered over 12 inches of rain. Those are the outer edges worth knowing if you are moving here, planning a trip, or thinking about a house.
