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

103 years with a frost

Across 103 years with a frost, the median last spring frost at Arad falls on 19 April and the median first autumn frost on 21 October, which leaves a median of 188 days between them.

In 1995 to 2025 the median growing season was 192 days. That is 2 days fewer than in 1897 to 1951.

Fitted over all years, the growing season changes by -1.1 days per decade at this station.

Frost dates and growing season at Arad
Measure	Median, all years	Earliest period (1897 to 1951)	Recent period (1995 to 2025)	Recent against earliest	Fitted trend
Last spring frost	19 April	17 April	11 April	6 days earlier	-0.4 days per decade
First autumn frost	21 October	24 October	18 October	6 days earlier	-1.5 days per decade
Growing days	188 days	194 days	192 days	2 days fewer	-1.1 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

132 years, 1880 to 2025

A day with at least 36.1 mm (1.4 in) of rain is expected about once in 2 years. A day with at least 72.8 mm (2.9 in) of rain is expected about once in 100 years.

Rainfall return levels at Arad: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	36.1 mm (1.4 in)
5 years	46.8 mm (1.8 in)
10 years	53.5 mm (2.1 in)
25 years	61.6 mm (2.4 in)
50 years	67.3 mm (2.6 in)
100 years	72.8 mm (2.9 in)

The levels come from a generalised extreme value (GEV) distribution fitted by L-moments to the wettest-day total of each year, 132 years of values from 1880 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: 75.6 mm (3.0 in) in 2020; 71.0 mm (2.8 in) in 1998; 65.8 mm (2.6 in) in 2016.

Station Changes

1 suspected

One change was suspected in the annual mean temperature of Arad, at 1977. Each is measured against neighbouring stations.

Relative to 5 neighbouring stations, the station's annual mean temperature from 1977 ran 0.3 C (0.5 F) lower than in the years before (likely change).

Suspected changes in the annual mean temperature at Arad, against neighbouring stations
Year	Shift (C)	Shift (F)	Strength	Neighbours
1977	-0.3	-0.5	likely	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

2010 to 2025 against 1961 to 1990

Over 2010 to 2025, Arad had a mean temperature of 12.4 C (54.3 F) and 578.4 mm (22.8 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Cameron (United States, 9,445 km away), Vega 2NW (United States, 9,359 km away) and Drobeta Turnu Severin (Romania, 195 km away).

Climate twins of Arad: 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
Cameron	United States	9,445 km (5,869 mi)	12.9 C (55.3 F)	482.7 mm (19.0 in)	0.85
Vega 2NW	United States	9,359 km (5,815 mi)	12.8 C (55.0 F)	451.3 mm (17.8 in)	0.91
Drobeta Turnu Severin	Romania	195 km (121 mi)	12.0 C (53.6 F)	686.2 mm (27.0 in)	0.92

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.
