Each chart shows one value per year; the dot marks the record year. TXx is the hottest daily maximum, TNn the coldest daily minimum, Rx1day and Rx5day the largest one-day and five-day rain totals, and CDD the longest run of days with less than 1 mm of rain. A year with missing days can understate an extreme.

Frost Dates and Growing Season

31 years with a frost

Across 31 years with a frost, the median last spring frost at Hebbronville falls on 11 February and the median first autumn frost on 6 December, which leaves a median of 297 days between them.

Frost dates and growing season at Hebbronville
Measure	Median, all years	Earliest period	Recent period (1968 to 2010)	Recent against earliest	Fitted trend
Last spring frost	11 February	n/a	12 February	n/a	+1.2 days per decade
First autumn frost	6 December	n/a	5 December	n/a	+2.0 days per decade
Growing days	297 days	n/a	297 days	n/a	+0.8 days per decade

A frost day is a day with a daily minimum at or below 0 C (32 F). The last spring frost and the first autumn frost are the last and first such days of the cold season, and growing days are the days between them. A negative trend for the last spring frost means it comes earlier.

Rainfall Return Levels

89 years, 1907 to 2011

Rainfall return levels at Hebbronville: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	76.9 mm (3.0 in)
5 years	116.7 mm (4.6 in)
10 years	146.1 mm (5.8 in)
25 years	187.1 mm (7.4 in)
50 years	220.7 mm (8.7 in)
100 years	256.9 mm (10.1 in)	Longer than the 89 years of record

The levels come from a generalised extreme value (GEV) distribution fitted by L-moments to the wettest-day total of each year, 89 years of values from 1907 to 2011.

A return level is an estimate. It is least reliable for the long periods, 50 and 100 years, and for any period longer than the record behind the fit, where the fit has to reach past the largest day actually observed. It is not a forecast.

The largest wettest-day totals in the fit: 238.8 mm (9.4 in) in 1971; 228.6 mm (9.0 in) in 1913; 215.9 mm (8.5 in) in 1919.
