Frost dates and growing season in Austin
In Austin the median last spring night at or below 32°F is February 20, and the median first autumn one is December 3 (NOAA P50 dates). NOAA's median length of the freeze-free season is 291 days. NOAA takes that median over each year's own season, so it need not equal the 286 days between the two median dates.
There is still a 10% chance of a 32°F night on or after March 14, and a 10% chance that the first one has come by November 15.
The chance that the last spring 32°F night comes on or after January 23 is 90%.
For a hard freeze (28°F or lower) the median dates are February 1 in spring and December 27 in autumn.
