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

78 years with a frost

Across 78 years with a frost, the median last spring frost at Glasgow falls on 10 May and the median first autumn frost on 27 September, which leaves a median of 138 days between them.

In 1996 to 2025 the median growing season was 138 days. That is 2 days fewer than in 1948 to 1977.

Fitted over all years, the growing season changes by +0.9 days per decade at this station.

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

78 years, 1948 to 2025

A day with at least 31.9 mm (1.3 in) of rain is expected about once in 2 years. A day with at least 75.8 mm (3.0 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, 78 years of values from 1948 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: 75.2 mm (3.0 in) in 1985; 64.8 mm (2.6 in) in 2007; 63.2 mm (2.5 in) in 1962.

No change in the annual mean temperature of this station was found against its neighbours.

Climate Twins

2011 to 2025 against 1961 to 1990

Over 2011 to 2025, Glasgow had a mean temperature of 6.9 C (44.3 F) and 346.7 mm (13.6 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Maurine 12SW (United States, 484 km away), Zeona 10 SSW (United States, 446 km away) and Bison (United States, 434 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.
