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

61 years with a frost

Across 61 years with a frost, the median last spring frost at Eldora falls on 27 April and the median first autumn frost on 6 October, which leaves a median of 163 days between them.

In 1991 to 2022 the median growing season was 165 days. That is 3 days more than in 1958 to 1989.

Fitted over all years, the growing season changes by +1.2 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

73 years, 1950 to 2022

A day with at least 67.9 mm (2.7 in) of rain is expected about once in 2 years. A day with at least 158.5 mm (6.2 in) of rain is expected about once in 100 years.

50 years143.1 mm (5.6 in)
100 years158.5 mm (6.2 in)Longer than the 73 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, 73 years of values from 1950 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: 189.2 mm (7.4 in) in 1950; 143.8 mm (5.7 in) in 2015; 133.4 mm (5.3 in) in 1969.

Station Changes

1 suspected

One change was suspected in the annual mean temperature of Eldora, at 2010. Each is measured against neighbouring stations.

  • Relative to 5 neighbouring stations, the station's annual mean temperature from 2010 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

2007 to 2022 against 1961 to 1990

Over 2007 to 2022, Eldora had a mean temperature of 8.5 C (47.2 F) and 989.5 mm (39.0 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Paw Paw 2S (United States, 349 km away), Rockford Gtr Rockford AP (United States, 330 km away) and Dubuque Rgnl AP (United States, 196 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.
