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
75 years with a frostAcross 75 years with a frost, the median last spring frost at Glasgow #2 falls on 14 May and the median first autumn frost on 24 September, which leaves a median of 130 days between them.
In 1952 to 2024 the median growing season was 141 days. That is 25 days more than in 1894 to 1936.
Fitted over all years, the growing season changes by +2.8 days per decade at this station.
| Measure | Median, all years | Earliest period (1894 to 1936) | Recent period (1952 to 2024) | Recent against earliest | Fitted trend |
|---|---|---|---|---|---|
| Last spring frost | 14 May | 19 May | 11 May | 8 days earlier | -1.2 days per decade |
| First autumn frost | 24 September | 15 September | 1 October | 16 days later | +1.6 days per decade |
| Growing days | 130 days | 116 days | 141 days | 25 days more | +2.8 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
55 years, 1895 to 1995A day with at least 34.9 mm (1.4 in) of rain is expected about once in 2 years. A day with at least 102.7 mm (4.0 in) of rain is expected about once in 100 years.
| Expected about once in | A day with at least | Note |
|---|---|---|
| 2 years | 34.9 mm (1.4 in) | |
| 5 years | 51.6 mm (2.0 in) | |
| 10 years | 63.1 mm (2.5 in) | |
| 25 years | 78.5 mm (3.1 in) | |
| 50 years | 90.4 mm (3.6 in) | |
| 100 years | 102.7 mm (4.0 in) | Longer than the 55 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, 55 years of values from 1895 to 1995.
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: 82.8 mm (3.3 in) in 1933; 81.5 mm (3.2 in) in 1940; 72.4 mm (2.9 in) in 1912.
Station Changes
1 suspectedOne change was suspected in the annual mean temperature of Glasgow #2, at 1943. Each is measured against neighbouring stations.
- Relative to 5 neighbouring stations, the station's annual mean temperature from 1943 ran 0.3 C (0.5 F) higher than in the years before (possible change).
| Year | Shift (C) | Shift (F) | Strength | Neighbours |
|---|---|---|---|---|
| 1943 | +0.3 | +0.5 | 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.
