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

80 years with a frost

Across 80 years with a frost, the median last spring frost at Smithville falls on 11 March and the median first autumn frost on 17 November, which leaves a median of 254 days between them.

In 1983 to 2017 the median growing season was 252 days. That is 9 days more than in 1923 to 1957.

Fitted over all years, the growing season changes by -0.2 days per decade at this station.

Frost dates and growing season at Smithville
Measure	Median, all years	Earliest period (1923 to 1957)	Recent period (1983 to 2017)	Recent against earliest	Fitted trend
Last spring frost	11 March	18 March	10 March	8 days earlier	-0.5 days per decade
First autumn frost	17 November	17 November	17 November	no change	-0.7 days per decade
Growing days	254 days	243 days	252 days	9 days more	-0.2 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

92 years, 1918 to 2017

A day with at least 83.9 mm (3.3 in) of rain is expected about once in 2 years. A day with at least 309.9 mm (12.2 in) of rain is expected about once in 100 years.

Rainfall return levels at Smithville: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	83.9 mm (3.3 in)
5 years	122.2 mm (4.8 in)
10 years	154.7 mm (6.1 in)
25 years	206.1 mm (8.1 in)
50 years	253.4 mm (10.0 in)
100 years	309.9 mm (12.2 in)	Longer than the 92 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, 92 years of values from 1918 to 2017.

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: 407.7 mm (16.1 in) in 1940; 327.7 mm (12.9 in) in 2017; 242.1 mm (9.5 in) in 1998.

Climate Twins

2003 to 2017 against 1961 to 1990

Over 2003 to 2017, Smithville had a mean temperature of 20.5 C (68.8 F) and 922.7 mm (36.3 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are San Antonio Intl AP (United States, 137 km away), Sealy (United States, 102 km away) and College STN Easterwood Fld (United States, 101 km away).

Twin station	Country	Distance away	Mean temperature, 1961-1990	Rain a year, 1961-1990	Climate difference
San Antonio Intl AP	United States	137 km (85 mi)	20.3 C (68.6 F)	787.7 mm (31.0 in)	0.68
Sealy	United States	102 km (63 mi)	20.4 C (68.7 F)	994.4 mm (39.1 in)	0.72
College STN Easterwood Fld	United States	101 km (63 mi)	19.8 C (67.6 F)	991.9 mm (39.1 in)	0.78

Twins are stations, not cities. A twin is one of the three stations at least 100 km away whose earlier climate is closest to this station's recent one, so a close match does not mean the two places look alike in other ways. A station move or a gap in a record can change that station's averages. The list describes past climate; it is not a forecast and does not say what caused any change. How twins are found, and a search for any station.
