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

85 years with a frost

Across 85 years with a frost, the median last spring frost at Blackfoot Fire Dept falls on 23 May and the median first autumn frost on 18 September, which leaves a median of 121 days between them.

In 1966 to 2023 the median growing season was 135 days. That is 35 days more than in 1896 to 1930.

Fitted over all years, the growing season changes by +4.7 days per decade at this station.

Growing days121 days100 days135 days35 days more+4.7 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

92 years, 1896 to 2021

A day with at least 23.2 mm (0.9 in) of rain is expected about once in 2 years. A day with at least 51.0 mm (2.0 in) of rain is expected about once in 100 years.

The levels come from a generalised extreme value (GEV) distribution fitted by L-moments to the wettest-day total of each year, 92 years of values from 1896 to 2021.

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: 46.7 mm (1.8 in) in 1897; 43.2 mm (1.7 in) in 1993; 42.4 mm (1.7 in) in 2014.

Station Changes

2 suspected

2 changes were suspected in the annual mean temperature of Blackfoot Fire Dept, at 1960 and 2003. Each is measured against neighbouring stations.

  • Relative to 5 neighbouring stations, the station's annual mean temperature from 1960 ran 0.6 C (1.0 F) lower than in the years before (possible change).
  • Relative to 5 neighbouring stations, the station's annual mean temperature from 2003 ran 0.3 C (0.6 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.

Climate Twins

1997 to 2023 against 1961 to 1990

Over 1997 to 2023, Blackfoot Fire Dept had a mean temperature of 8.8 C (47.8 F) and 309.5 mm (12.2 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Tensleep 4NE (United States, 411 km away), Scipio (United States, 439 km away) and Midwest (United States, 492 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.
