Climate Trend

83 complete years, 1909 to 2025
Annual mean temperature at Eureka 1E as warming stripes, 1909 to 2025 One stripe for each of 83 complete years at Eureka 1E, 1909 to 2025. Blue stripes are years cooler than the station's own mean of 13.7 C (56.6 F); red stripes are warmer. The coolest year was 2008, at 12.0 C (53.5 F), and the warmest was 1931, at 15.4 C (59.6 F).

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

83 years with a frost

Across 83 years with a frost, the median last spring frost at Eureka 1E falls on 13 April and the median first autumn frost on 19 October, which leaves a median of 188 days between them.

In 1993 to 2025 the median growing season was 191 days. That is 1 day more than in 1909 to 1965.

Fitted over all years, the growing season changes by +0.4 days per decade at this station.

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

102 years, 1897 to 2025

A day with at least 73.1 mm (2.9 in) of rain is expected about once in 2 years. A day with at least 187.2 mm (7.4 in) of rain is expected about once in 100 years.

25 years143.9 mm (5.7 in)
50 years164.9 mm (6.5 in)
100 years187.2 mm (7.4 in)

The levels come from a generalised extreme value (GEV) distribution fitted by L-moments to the wettest-day total of each year, 102 years of values from 1897 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: 176.8 mm (7.0 in) in 2007; 174.8 mm (6.9 in) in 2019; 172.2 mm (6.8 in) in 1961.

Station Changes

1 suspected

One change was suspected in the annual mean temperature of Eureka 1E, at 2001. Each is measured against neighbouring stations.

  • Relative to 5 neighbouring stations, the station's annual mean temperature from 2001 ran 0.2 C (0.4 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

2008 to 2025 against 1961 to 1990

Over 2008 to 2025, Eureka 1E had a mean temperature of 13.3 C (56.0 F) and 952.5 mm (37.5 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Stockton Dam (United States, 220 km away), Waterloo 6SW (United States, 530 km away) and Mound City (United States, 131 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.
