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

139 years with a frost

Across 139 years with a frost, the median last spring frost at Green Bay falls on 5 May and the median first autumn frost on 8 October, which leaves a median of 153 days between them.

In 1996 to 2025 the median growing season was 159 days. That is 3 days fewer than in 1887 to 1916.

Fitted over all years, the growing season changes by -0.3 days per decade at this station.

First autumn frost8 October10 October13 October3 days later-0.3 days per decade
Growing days153 days162 days159 days3 days fewer-0.3 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

139 years, 1887 to 2025

A day with at least 46.9 mm (1.8 in) of rain is expected about once in 2 years. A day with at least 116.0 mm (4.6 in) of rain is expected about once in 100 years.

25 years90.1 mm (3.5 in)
50 years102.7 mm (4.0 in)
100 years116.0 mm (4.6 in)

The levels come from a generalised extreme value (GEV) distribution fitted by L-moments to the wettest-day total of each year, 139 years of values from 1887 to 2025.

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: 124.5 mm (4.9 in) in 1990; 111.5 mm (4.4 in) in 1912; 104.6 mm (4.1 in) in 2000.

Climate Twins

2011 to 2025 against 1961 to 1990

Over 2011 to 2025, Green Bay had a mean temperature of 8.1 C (46.6 F) and 861.4 mm (33.9 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Milford Gm Proving Ground (United States, 416 km away), Greenville 2 NNE (United States, 271 km away) and Angola (United States, 403 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.
