Frost dates for Sugar Land, Texas
Texas · first & last freeze, from NOAA 1991–2020 climate normals
In a typical year, the last spring freeze around Sugar Land comes near February 9 and the first fall freeze near December 13. One year in ten, a freeze still arrives after March 11 in spring — and one year in ten, the first fall freeze has already landed by November 19. NCEI's own growing-season statistic (days between freezes, percentiled per year) puts the median at 305 days.
Freeze-date probabilities, three thresholds
| Threshold | Last spring — 9 in 10 years past by | Last spring — typical (median) | Last spring — 1 in 10 years later than | First fall — 1 in 10 years by | First fall — typical (median) | First fall — 9 in 10 years by |
|---|---|---|---|---|---|---|
| 36°F — near-freezing (frost can occur) | February 2 | March 2 | March 25 | November 9 | November 29 | December 20 |
| 32°F — freezing | January 13 | February 9 | March 11 | November 19 | December 13 | January 13 |
| 28°F — hard freeze | December 26 | January 28 | February 28 | November 30 | January 1 | February 2 |
Measured at Sugar Land, TX (USC00418728), 2.4 mi from the city's census reference point, elev. 84 ft. NOAA/NCEI 1991–2020 normals. Read each date column as odds over the 30-year record — e.g. "9 in 10 years past by" means only one spring in ten saw a later freeze than that date.
Frost-free windows (computed)
| Window (32°F ends) | Opens | Closes | Length |
|---|---|---|---|
| Cautious (1-in-10 freeze risk at each end) | March 11 | November 19 | 253 days |
| Typical (median freeze dates) | February 9 | December 13 | 307 days |
| Gambler's (9-in-10 freeze risk at each end) | January 13 | January 13 | 365 days |
Pure arithmetic on the freeze-date percentiles above — the "cautious" window opens on the date only 1 year in 10 still sees a later spring freeze, and closes on the date by which only 1 year in 10 has already frozen.
