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

74 years with a frost

Across 74 years with a frost, the median last spring frost at Dulce falls on 15 June and the median first autumn frost on 14 September, which leaves a median of 88 days between them.

In 1987 to 2020 the median growing season was 97 days. That is 12 days more than in 1907 to 1969.

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

Frost dates and growing season at Dulce
Measure	Median, all years	Earliest period (1907 to 1969)	Recent period (1987 to 2020)	Recent against earliest	Fitted trend
Last spring frost	15 June	16 June	14 June	2 days earlier	-0.2 days per decade
First autumn frost	14 September	13 September	16 September	3 days later	-0.6 days per decade
Growing days	88 days	85 days	97 days	12 days more	-0.4 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

96 years, 1907 to 2020

A day with at least 29.1 mm (1.1 in) of rain is expected about once in 2 years. A day with at least 58.9 mm (2.3 in) of rain is expected about once in 100 years.

Rainfall return levels at Dulce: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	29.1 mm (1.1 in)
5 years	36.7 mm (1.4 in)
10 years	41.9 mm (1.6 in)
25 years	48.6 mm (1.9 in)
50 years	53.7 mm (2.1 in)
100 years	58.9 mm (2.3 in)	Longer than the 96 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, 96 years of values from 1907 to 2020.

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: 63.5 mm (2.5 in) in 1931; 60.7 mm (2.4 in) in 1923; 50.0 mm (2.0 in) in 1968.

Station Changes

1 suspected

One change was suspected in the annual mean temperature of Dulce, at 2013. Each is measured against neighbouring stations.

Relative to 5 neighbouring stations, the station's annual mean temperature from 2013 ran 0.5 C (0.9 F) higher than in the years before (possible change).

Suspected changes in the annual mean temperature at Dulce, against neighbouring stations
Year	Shift (C)	Shift (F)	Strength	Neighbours
2013	+0.5	+0.9	possible	5

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

2002 to 2020 against 1961 to 1990

Over 2002 to 2020, Dulce had a mean temperature of 8.4 C (47.1 F) and 414.2 mm (16.3 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Spokane Intl AP (United States, 1,467 km away), Manti (United States, 480 km away) and Ruby Lake Nwr (United States, 822 km away).

Twin station	Country	Distance away	Mean temperature, 1961-1990	Rain a year, 1961-1990	Climate difference
Spokane Intl AP	United States	1,467 km (912 mi)	8.4 C (47.2 F)	419.8 mm (16.5 in)	0.54
Manti	United States	480 km (298 mi)	8.7 C (47.6 F)	349.3 mm (13.8 in)	0.57
Ruby Lake Nwr	United States	822 km (511 mi)	8.3 C (46.9 F)	326.0 mm (12.8 in)	0.59

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.
