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

67 years with a frost

Across 67 years with a frost, the median last spring frost at Ellsworth 1E falls on 7 May and the median first autumn frost on 2 October, which leaves a median of 147 days between them.

In 1992 to 2025 the median growing season was 146 days. That is 8 days fewer than in 1945 to 1981.

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

Frost dates and growing season at Ellsworth 1E
Measure	Median, all years	Earliest period (1945 to 1981)	Recent period (1992 to 2025)	Recent against earliest	Fitted trend
Last spring frost	7 May	5 May	10 May	5 days later	+0.2 days per decade
First autumn frost	2 October	1 October	4 October	3 days later	+0.5 days per decade
Growing days	147 days	154 days	146 days	8 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

72 years, 1945 to 2025

A day with at least 60.7 mm (2.4 in) of rain is expected about once in 2 years. A day with at least 161.9 mm (6.4 in) of rain is expected about once in 100 years.

10 years	99.9 mm (3.9 in)
25 years	123.0 mm (4.8 in)
50 years	141.8 mm (5.6 in)
100 years	161.9 mm (6.4 in)	Longer than the 72 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, 72 years of values from 1945 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: 180.3 mm (7.1 in) in 1992; 145.5 mm (5.7 in) in 2020; 115.1 mm (4.5 in) in 1987.

No change in the annual mean temperature of this station was found against its neighbours.

Climate Twins

2010 to 2025 against 1961 to 1990

Over 2010 to 2025, Ellsworth 1E had a mean temperature of 7.0 C (44.5 F) and 908.0 mm (35.7 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Preston (United States, 122 km away), Montello Wwtp (United States, 272 km away) and Hillsboro (United States, 207 km away).

Climate twins of Ellsworth 1E: stations whose 1961 to 1990 climate is closest to its 2010 to 2025 climate
Twin station	Country	Distance away	Mean temperature, 1961-1990	Rain a year, 1961-1990	Climate difference
Preston	United States	122 km (76 mi)	6.8 C (44.2 F)	834.9 mm (32.9 in)	0.78
Montello Wwtp	United States	272 km (169 mi)	7.2 C (44.9 F)	813.0 mm (32.0 in)	0.82
Hillsboro	United States	207 km (129 mi)	7.1 C (44.7 F)	797.8 mm (31.4 in)	0.84

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.
