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

99 years with a frost

Across 99 years with a frost, the median last spring frost at Port Gibson 1 NE falls on 23 March and the median first autumn frost on 4 November, which leaves a median of 223 days between them.

In 1977 to 2022 the median growing season was 232 days. That is 8 days more than in 1895 to 1928.

Fitted over all years, the growing season changes by +1.0 days per decade at this station.

Growing days223 days224 days232 days8 days more+1.0 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

116 years, 1897 to 2022

A day with at least 102.7 mm (4.0 in) of rain is expected about once in 2 years. A day with at least 234.3 mm (9.2 in) of rain is expected about once in 100 years.

25 years188.0 mm (7.4 in)
50 years210.9 mm (8.3 in)
100 years234.3 mm (9.2 in)

The levels come from a generalised extreme value (GEV) distribution fitted by L-moments to the wettest-day total of each year, 116 years of values from 1897 to 2022.

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: 247.1 mm (9.7 in) in 1964; 227.3 mm (8.9 in) in 1990; 202.2 mm (8.0 in) in 1974.

Station Changes

1 suspected

One change was suspected in the annual mean temperature of Port Gibson 1 NE, at 1986. Each is measured against neighbouring stations.

  • Relative to 5 neighbouring stations, the station's annual mean temperature from 1986 ran 0.2 C (0.4 F) higher than in the years before (possible 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.
