Weather extremes

How extreme does Lake Jackson's weather get?

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

Based on 50+ years of daily weather observations (1971–present), from the Freeport 2 Nw station 8 km away. Updated through June 2026 — 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 Lake Jackson has recorded — each shown against what a normal day that time of year looks like.

🔥 Hottest day
105°F Sep 4, 2000

That is about 16°F hotter than a normal September afternoon in Lake Jackson (typical high near 89°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.

Lake Jackson's record heat sits well above even a hot day for the season — September's 105°F is about 16°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, Lake Jackson's warmest days reach the low 90s°F and its coldest nights drop to the mid-40s°F. But across the record it has gone as high as 105°F and as low as 13°F. A single day has delivered over 17 inches of rain or close to 1 inches of snow. Those are the outer edges worth knowing if you are moving here, planning a trip, or thinking about a house.
