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

121 years with a frost

Across 121 years with a frost, the median last spring frost at Jackson Exp STN falls on 7 April and the median first autumn frost on 26 October, which leaves a median of 202 days between them.

In 1995 to 2025 the median growing season was 214 days. That is 13 days more than in 1896 to 1930.

Fitted over all years, the growing season changes by +1.8 days per decade at this station.

First autumn frost26 October22 October1 November10 days later+1.1 days per decade
Growing days202 days201 days214 days13 days more+1.8 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

125 years, 1893 to 2024

A day with at least 76.9 mm (3.0 in) of rain is expected about once in 2 years. A day with at least 183.4 mm (7.2 in) of rain is expected about once in 100 years.

Expected about once inA day with at leastNote
2 years76.9 mm (3.0 in)
5 years99.8 mm (3.9 in)

25 years141.3 mm (5.6 in)
50 years161.4 mm (6.4 in)
100 years183.4 mm (7.2 in)

The levels come from a generalised extreme value (GEV) distribution fitted by L-moments to the wettest-day total of each year, 125 years of values from 1893 to 2024.

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: 199.6 mm (7.9 in) in 1987; 181.6 mm (7.1 in) in 2002; 160.0 mm (6.3 in) in 1935.

Station Changes

1 suspected

One change was suspected in the annual mean temperature of Jackson Exp STN, at 1995. Each is measured against neighbouring stations.

  • Relative to 5 neighbouring stations, the station's annual mean temperature from 1995 ran 0.2 C (0.3 F) lower than in the years before (likely change).

Possible change at the station (a move, a new instrument or a new site); the record is kept as measured. A "likely" change has a larger test statistic than a "possible" one. Neither says why the station differs from its neighbours. How changes are found, and the largest ones.

Climate Twins

2011 to 2025 against 1961 to 1990

Over 2011 to 2025, Jackson Exp STN had a mean temperature of 16.0 C (60.9 F) and 1,539.3 mm (60.6 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Water Valley (United States, 177 km away), Huntsville Intnl AP (United States, 217 km away) and Vernon (United States, 219 km away).

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.
