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

47 years with a frost

Across 47 years with a frost, the median last spring frost at Maastricht-1 falls on 10 April and the median first autumn frost on 2 November, which leaves a median of 206 days between them.

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

Frost dates and growing season at Maastricht-1
Measure	Median, all years	Earliest period	Recent period (1923 to 1952)	Recent against earliest	Fitted trend
Last spring frost	10 April	n/a	4 April	n/a	-0.5 days per decade
First autumn frost	2 November	n/a	4 November	n/a	-0.8 days per decade
Growing days	206 days	n/a	210 days	n/a	-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.

Station Changes

2 suspected

2 changes were suspected in the annual mean temperature of Maastricht-1, at 1923 and 1946. Each is measured against neighbouring stations.

Relative to 5 neighbouring stations, the station's annual mean temperature from 1923 ran 0.2 C (0.3 F) higher than in the years before (likely change).
Relative to 5 neighbouring stations, the station's annual mean temperature from 1946 ran 0.8 C (1.4 F) lower than in the years before (likely change).

Suspected changes in the annual mean temperature at Maastricht-1, against neighbouring stations
Year	Shift (C)	Shift (F)	Strength	Neighbours
1923	+0.2	+0.3	likely	5
1946	-0.8	-1.4	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.
